Motor oils and everything you need to know about motor oils. Motor oils and everything you need to know about motor oils Oil for Mazda 6 two-stroke engines
6 provides lubrication of rubbing engine parts, protection against corrosion and heat removal from moving elements. Timely replacement of engine oil ensures reliable engine operation, and the life of the power unit directly depends on the quality of the oil used.
How to choose oil and how much to fill it in
You should select engine oil for Mazda 6 according to the parameters recommended by the manufacturer in the Operating Manual. In the process of improving Mazda 6 engines from generation to generation, the requirements for engine oil increased. Before deciding which 6 to buy and how much oil is needed to change, check the car and engine model.
The Mazda 6 GG gasoline engine (2002-2008) requires the following engine oil characteristics:
- oil type SJ in accordance with API classification;
- recommended viscosity 5W-30.
- Analogues:
- viscosity 5W-20;
- oil type SG, SH, SJ, SL according to API classification;
The volume of engine oil, depending on the engine, is 3.5-4.4 liters.
Gasoline power units Mazda 6 GH (2007-2012) use oil:
- Original DEXELIA Mazda oil:
- oil type SL in accordance with API classification;
- recommended viscosity 5W-30, 5W-20, 10W-40
- Analogues:
- viscosity 5W-30.5W-20;
- oil type SL, SM according to API classification;
Engine oil volume depending on the engine is 4.3-5.0 liters.
For petrol engines SkyActyv Mazda 6 GJ from 2012 it is recommended:
- Original Mazda Supra 0W-20 and Mazda Ultra 5W-30 oil:
- Analogues:
- viscosity 0W-20, type SM, SN;
- viscosity 5W-30, type SM, SL.
The volume of engine oil, depending on the engine, is 4.2-4.5 liters.
Types of motor oils
Before deciding 6, you need to understand what kind of motor oil there is.
The international community has adopted a standard classification of motor oils:
- By engine type: for gasoline engines, for diesel engines or universal oil (API classification).
- According to viscosity-temperature indicators: summer, winter and all-season oils (SAE classification).
- By type of motor oil base: mineral, synthetic and semi-synthetic. Oil containing a base produced by chemical synthesis is called synthetic. Mineral - has a petroleum base. When an oil industrialist pours a mixture of synthetic and mineral bases in different proportions into a canister, the result is “semi-synthetic.”
High-tech Mazda 6 engines are filled with modern synthetic all-season motor oil of the SM, SN level with a viscosity of 0W-20, 5W-30.
When to change the oil
After you have figured out what kind of oil to fill in the Mazda 6, the question arises when to change the engine oil. Every oil has its own resource, and even if you filled it with synthetic oil, this does not mean that you can forget about replacing it.
According to Mazda regulations, the frequency of engine oil changes is at each maintenance no less than every 20,000 km or every 12 months of vehicle operation. These are just the manufacturer’s recommendations for the average car enthusiast; in reality, there are external factors that affect the oil change interval:
- driving style;
- duration of trips;
- frequency of machine use;
- fuel quality;
- conditions and area of vehicle operation.
Replacement frequency
The trend among motor oil manufacturers is to improve the quality and performance of lubricants every year. Drivers tend to increase the frequency of engine oil changes. It gets to the point that “advanced” car enthusiasts do this every 3-4 thousand km or 3-4 times a year. How often do you change the oil? In Russian conditions of large cities, experts recommend changing the oil twice a year - before the winter and summer seasons.
How to check the condition of the oil
The textbook way to check the condition of the oil under normal conditions is drop analysis, which involves the following procedure:
- Let the engine run for 5-10 minutes and turn off.
- We take out the oil dipstick and put a drop of oil on a piece of paper.
- After two hours of drying, you can evaluate the result.
How to find out in advance that the oil has become unusable
Deviations in engine operation may indicate that the engine oil is unsuitable for further use. High-quality and correctly selected motor oil is the key to reliable engine operation. Therefore, every owner of a Mazda 6 must monitor the level, quality and timely replacement of oil. After all, you won’t go far without oil!
The engine life directly depends on the quality of motor oils. This is especially true for cars with powerful engines that are installed in the Mazda 6. In addition to good power characteristics, this engine is also very sensitive to the quality of motor oils - you can’t put anything in there. At best, low-quality lubricants will evaporate very quickly. In the worst case, the power unit will fail. You should very carefully and carefully select oil for the Mazda 6, taking into account all the characteristics of its engine. Only then will it be possible to drive for a long time and count on the reliability laid down by the manufacturer.
The Japanese manufacturer gives simple recommendations - in order for the machine to serve for a long time, you need to fill only original products. This is only Dexelia 5W30 or 10W40. But to select high-quality lubricants, recommendations alone are not enough.
When choosing oil for the Mazda 6, it is important to take into account the year of manufacture of the car, as well as its series. Service specialists and experienced drivers recommend using different oils for cars that are used extremely rarely and that have high mileage and are driven every day.
First generation cars
So, for first-generation models, which were produced from 2002 to 2007, manufacturers recommend using mineral or semi-synthetic oils. The owners, in turn, having read autoblogs, change the Mazda 6 oil only using synthetic products, believing that this will be better. And this approach is fundamentally wrong - for cars that are already quite old and have long mileage, you need mineral oil. It will fit much better.
For winter operation, it is better to select oils with lower viscosity - 0W30 or 5W40. In this case, additives must belong to the SM class. In the summer, you can switch to 25W40 fluids. If climatic conditions allow, then it makes sense to use all-season
Second generation models
The second generation of this model was produced from 2008 to 2012. This is where you need to use higher quality synthetic oils. The oil in the Mazda 6 engine, produced after 2011, may be semi-synthetic - manufacturers fully allow this.
The class of lubricating fluids must be SN and higher for gasoline power units, and for diesel ones - not lower than CJ. As for viscosity, it remains the same.
Third generation
These cars were produced from 2013 to 2016. For them, only synthetic motor oils whose class corresponds to SN or CJ-4 are recommended. For summer operation, fill in 15W60, for winter use - 0W60. Recommended brands of oils for Mazda 6 are Shell, Mobil, Castrol.
About original oils
For gasoline engines and cars intended for use in Europe, Dexelia lubricants are recommended. The oil type must comply with API SJ. According to ACEA classification these are A1 or A3 oils. As for viscosity, the instructions indicate 5W30 at temperatures from -29 to +40 degrees.
Alternatively, class SL can be poured and the viscosity should be 5W20. According to the instructions, the recommended oil for Mazda 6 for all countries except European ones should be SG, SH, SL. This is true for first and second generation gasoline engines.
With Skyaktive engines for third-generation cars, the recommendations are different. The instructions recommend using Mazda Original Supra Oil 0W20 oils. Mazda Original Ultra 5W is also recommended. For third generation diesel engines, Oil Supra DPF is offered with viscosity 0W30 and 5W30. These are relatively liquid oils. However, they are suitable for use in both summer and winter.
How much oil does the engine need?
It is important not only to choose the right oil for the Mazda-6, but also to fill it in exactly the right quantity.
So, for L8 or LF power units you need 4.3 liters including the oil filter or 3.9 liters without replacing the cleaning element. However, experts still recommend changing this element during vehicle maintenance. The filter becomes clogged and dirty oil begins to penetrate through the bypass valve. To avoid contamination, the part is changed at the same frequency as the lubricant. For L8 engines, 3.5 liters are required with filter replacement or 3.1 liters without replacement. This is data for Mazda engines of the sixth series of the first generation.
This applies to gasoline units, of which the majority are in Russia. But there are also diesel models on our market. With them everything is a little different. The recommended oil volume for diesel engines is 5 liters with filter replacement or 4.8 liters when there is no need to change this element.
Next, let's look at the second generation of Mazda-6. In this case, the engines are similar to the first generation. These are L8 and LF, respectively, the oil volume is similar. L5 diesel units require 5 liters of oil with a filter change or 4.6 liters without replacement. The manufacturer states that all indicated volumes are approximate, and the amount of oil should be regularly checked with a dipstick.
For third generation and 2-liter engines with a filter change, you need to fill in 4.2 liters, and without - 4 liters. For a 2.5 liter engine, 4.5 is usually poured with a filter, and 4.3 without. The third generation diesel is filled with 5.1 liters. This is if the filter is changed. And 4.8 liters is filled in if the filter does not need to be changed.
Manufacturers' recommendations are, of course, correct and good, but each owner has his own opinion about lubricating fluids. But statistics show that the most suitable brands are Mobil, Castrol, Shell, Zeke and even Xado.
As for Declessia, it is not recommended to fill it, especially if the car is used. The engine will burn this oil in quantities that cannot be considered normal according to the instructions. In addition, the additives there are far from the best, and the price of these oils is very high.
If the machine consumes oil in large quantities, but there are no breakdowns, then it is worth experimenting with the viscosity level. Experienced owners recommend changing the oil in Mazda 6 using semi-synthetic lubricants with a viscosity of 10W40.
The products of the companies "Valvoine", Aral, Neste perform well. These are not cheap oils, but if lubricant consumption is high, you should not fill in low-quality liquids. On the contrary, it is better to protect the engine from possible negative consequences. HighTech 5W30 products perform well - they practically do not burn out and can easily withstand mileage above the norm.
Transmission and oils
The oil needs to be changed not only in the engine, but also in the automatic transmission. Changing the oil in the Mazda 6 automatic transmission is carried out using the original product - Mazda ATF. Both experts and manufacturers recommend using only this product.
But there are also analogs that are no better in quality, but no worse than the original liquid. This is Dextron-6, automatic transmission oil for BMW 7045E, Nissan Matic, Honda 31, Toyota T-4. All these fluids are confidently used in Mazda automatic transmissions.
Mazda ATF-FZ fluid is intended for Skyactive gearboxes. These oils are recommended for automatic transmissions. The fluid has better friction characteristics, as well as a high level of thermal-oxidative stability. This oil in the Mazda 6 box allows for reliable operation of the mechanism and smoother shifts.
How much oil should I use in a Mazda automatic transmission?
Automatic transmissions require 7.2 liters of oil if the change is complete. If the replacement is partial, then only half the volume will be poured into the mechanism. If the car has high mileage and the oil has not been changed, the manufacturer recommends only a complete replacement. The oil change schedule for automatic transmissions is 60 thousand km. But this figure is relevant if the car is operated in mild conditions.
Taking into account the Russian climate and the condition of the roads, experts recommend changing the automatic transmission oil every 35-40 thousand kilometers.
Conclusion
Few people know what kind of oil to fill in the Mazda 6, because the manufacturer recommends only original products. As you can see, there are more affordable analogues that are more suitable for the Russian climate and Russian realities. In addition, analogues are much cheaper.
Every motorist knows well that the choice of oil for Mazda 6, as for any other vehicle, must be made in accordance with the requirements of the service book. However, it often happens that standard parameters do not always reach optimal values.
What kind of oil to fill in the Mazda 6 engine
The sixth Mazda is very sensitive to the quality of engine oil. If it is of low quality, it will begin to actively evaporate - at best. Or it will simply damage the engine. Hence the conclusion: you need to choose the oil very carefully and take into account all its characteristics in order to drive for a long time without repairs.
- 5W-30;
- 10W-40.
However, such parameters will not be enough. To make an informed choice, you need to take into account the series of the car and the year of its manufacture. A new vehicle requires one type of lubricant, while a car with high mileage requires a completely different one.
Mazda, which came off the assembly line between 2002 and 2007, usually runs on semi-synthetic or mineral oil. Quite often, the owners of such cars try to choose the best lubricants for it and fill the engine with synthetics. It's better not to do this. For cars manufactured 10-15 years ago, mineral motor oil is more suitable.
To operate Mazda in winter, you need to use a lubricant with a viscosity of 0W-30 or 5W-40. Moreover, the composition must contain additives with the SM class. In summer, oil with a viscosity of 25W-40 is suitable. For the middle zone climate, you can use an all-season one with a viscosity coefficient of 15W-40.
For cars produced in 2008-2012, higher quality oil is needed. In this case, you cannot do without synthetics. You can also opt for semi-synthetics, but the lubricant class for a gasoline internal combustion engine should be SN, and for a diesel unit - CJ.
The latest generation includes cars manufactured between 2013-2016. They only contain synthetic lubricant, the class of which must be:
- CJ-4.
During the summer months, viscosity values change. 15W-60 is considered optimal. With the onset of cold weather, 0W-60 is poured into the engine.
Of course, everyone chooses for themselves which oil to fill in the Mazda 6. However, statistical data show that world-class motor oils are most often used:
- Castrol;
- Mobile;
- Shell;
- Hado.
If the car has run more than 100,000 km, Dexelia should not be filled. It begins to evaporate very quickly, which does not meet the standard set by the manufacturer. It must be said that SL class additives cannot be considered the best, and you have to pay very dearly for such a lubricant.
Sometimes it becomes noticeable how quickly the car “eats” the lubricant. To solve this problem, it is worth trying to find a more suitable viscosity. You can use semi-synthetics, the viscosity of which corresponds to 10W-40. For such cases, lubricants are often used:
- Valvolin;
- Neste;
- Aral.
Of course, they are quite expensive, but they reliably protect the engine from damage.
The Mazda 6 is suitable for the latest HighTech oil with a viscosity coefficient of 5W-30. Unlike others, it does not burn or evaporate. You can drive it even more than the standard for the replacement.
TNK Magnum Professional C3
This domestic oil, no matter how surprising it may be, ranks first in quality and cost. It is very often poured into Mazda 6, as it practically does not burn out. Similar to Castrol, it can operate on fuels that have a high sulfur content. In addition, the composition includes additives that protect the internal combustion engine from increased wear.

Which viscosity should I choose?
All answers
SAE viscosity is the generally accepted viscosity classification standard for motor oils SAE J300. The numbers hide the viscosity ranges defined by the standard into which a given sample must fit. If the oil is “all-season”, two numbers are indicated on the canister - for “cold start” and for the operating temperature of a warm engine. The first digit is separated from the second by the letter “W” - “winter”. Since almost all modern oils produced are all-season, a combined coding has become generally accepted, for example: 5W (cold start) 40 (operating temperature). In laboratory conditions, the shear force and oil pumpability at low temperatures are determined - this is important for the very possibility of starting a cold engine. The lower the number, the thinner the oil and the more suitable it is for cold start conditions. After reaching the operating temperature (and this is already about 40 degrees and above - a few minutes after starting), the influence of this parameter on the performance characteristics of the oil becomes insignificant. The second value becomes important - kinematic viscosity at engine operating temperature (about 100 degrees). The oil, obviously, should not be too liquid at operating temperature, which increases in proportion to the engine load and can reach 150-180 degrees and even higher. For example, in the area of the piston rings, where the oil takes away a significant part of the heat generated as a result of fuel combustion. A layer that is too thin may be susceptible to tearing: it will not provide the required protection and will lead to accelerated wear. Too thick - it will create a constant excess of lubricant in the area of \u200b\u200bthe piston grooves, which will gradually lead to coking (loss of mobility) of the piston rings under certain conditions - such as low engine speeds, typical of standing in a traffic jam. In addition, it is worth paying attention that the high-temperature viscosity of “40” and “60” differs in absolute numbers by approximately twofold - this means that power losses increase significantly, which, other things being equal, can reach 10%, which also leads to deterioration fuel efficiency - who would like that with thicker oil the car is “dumb” and eats too much gasoline?
Which viscosity should I choose?
In modern reality, we are dealing with a universal all-season oil, with ranges according to SAE 0-25W, and 20-60 for operating temperature. In practice, there are no oils that cover the entire temperature range: oils with extremely low low-temperature viscosity have average high-temperature indicators - 0W40, 5W40. Thick oils, accordingly, are quite thick even at low temperatures - 10W60, 5W50, 20W60. Obviously, for universal year-round operation, all other things being equal, it is worth focusing on medium viscosity ranges, for example 0W40, 5W40 and the like - such oils will ensure reliable engine starting at temperatures typical for central Russia and will provide adequate protection for moving engine parts during operation in operating speed range of a conventional engine: 600-6000 rpm. All this with optimal friction losses, which will provide optimum fuel efficiency, as well as power.
Low-viscosity oils, such as 0W30, or even 0W20, are created to reduce internal losses (fuel economy) and for a conventional engine can only be recommended for a theoretical improvement in fuel efficiency (about 2% in the test cycle), as well as to achieve a slight improvement in power performance at certain operating conditions. Such oils (or rather, recommendations for their use) are typical for cars in the Asian and North American markets and may (or may not) be related to the design features of the engine - the geometry of the oil channels, the location of the oil nozzles, etc. In the second case, there are no obstacles to using other (optimal for a given region) viscosity ranges.
Consideration of the viscosity characteristics of an oil in isolation from a specific sample is practically meaningless - viscosity is only one of the quality characteristics, which in turn has a dependence, as well as a direct and indirect influence on the integral indicator of product quality in the consumer sense - it is always necessary to consider a set of consumer parameters. The oil can be selected optimally in terms of viscosity, but this does not guarantee anything other than cold starting capability and oil film stability.
Oils with a markedly high viscosity (they contain a thickener) provide maximum oil film thickness at high temperatures and high speeds, in exchange for high losses and deterioration in fuel efficiency in standard operating conditions. Typical high viscosity ranges for commercial oils: "10W60", "20W60", "5W50". Indeed, such oils can be recommended to protect the engine in extreme operation modes, as well as in the case of specific modes of use: for example, long-term operation of the engine at maximum speed.
Contrary to popular belief, the so-called. "racing" brands of oils do not always have high viscosity. A typical oil for a high-speed sports engine “for racing” is “15W40” - such an engine starts only after preheating, the “winter” number is practically insignificant. In turn, such a narrow range gives greater freedom when choosing a base for an oil composition. For qualification, extremely low-viscosity oil of the “0W20” type can also be used - to achieve maximum results - minimum power losses. In the case, I repeat, of long-term operation of the engine in the maximum speed zone, for example, during the Le Mans 24 racing, the use of oil with a viscosity of 10W60 may be justified - this is where it belongs. But in a typical civilian engine - no.
Conclusion: for everyday, year-round, even extremely intensive use (not racing, not testing, etc.), oils with a medium range of viscosities such as 0w40, 5w40 and the like are absolutely universal. The use of low-viscosity, or, conversely, too thick oils, with the upper range of SAE 20, 30, 50 and 60 serves to solve a narrow range of problems and can lead to increased engine wear, ring coking, increased fuel consumption, reduced power, etc. I think it is easy for the reader to compare his mode of movement with those described above and make a choice. Certain specificities also occur with strong deviations from the climatic norm - in cold climates, low-viscosity oils are optimal, in extremely hot climates, thick ones.
Motor oils have different classes, quality groups, and differ in viscosity characteristics. The variety of these parameters is due to differences in the types of engines of different car models. In this article, we will describe the recommended engine oil for Mazda 6, the use of which contributes to efficient engine operation.
Depending on the engine type, the Mazda 6 manufacturer recommends using various lubricants.

- Motor oil 5W-20, poured at temperatures from -30 0 C (and below) to +27 0 C (and above), corresponding to API - SL or SM or ACEA with quality group A3/A5.
While the car is under the warranty period, you must use original Mazda DEXELIA motor lubricants with a viscosity of 10W-40 or 5W-30. If the power unit runs on non-original lubricant, then the factory warranty does not apply to the car engine.
The volume of engine oil required when replacing is determined by the type of Mazda 6 engine:
- Auto engines L8 and LF:
- 4.3 l including oil filter change;
- 3.9 l without replacing the filter device.
- L5 motors:
- 5.0 l with oil filter change;
- 4.6 l excluding oil filter replacement.
The manufacturer indicates that these volumes are approximate; the required amount of lubricant must be monitored using the dipstick when changing the oil.
Mazda 6 III GJ since 2012 (Skyactiv)
Gasoline car engines Skyactiv-G 2.0 and Skyactiv-G 2.5
In accordance with the operating instructions for the Mazda 6 car, it is allowed to fill in oils that meet the requirements:
- Mazda Original Oil Supra 0w - 20 is used in the temperature range from -35 0 C (or less) to +35 0 C (or more);
- Mazda Original Oil Ultra with a viscosity of 5w - 30 is used in temperature conditions from -30 0 C (or less) to +35 0 C (or more);
- An alternative motor oil that meets API standards - SN or SM with a viscosity of 0w - 20, is used in the temperature range from -35 0 C (or less) to +35 0 C (or more).
- An alternative lubricant corresponding to API classification - SL or SM or ACEA with quality group A3/A5 with a viscosity of 5w - 30 is poured at temperature conditions from -30 0 C (or less) to +35 0 C (or more).
The volume of lubricant required during replacement is:
- Engine Skyactiv-G 2.0:
- 4.2 l with oil filter change;
- 4.0 l without replacing the oil filter unit.
- Engine Skyactiv-G 2.5:
- 4.5 l with oil filter replacement;
- 4.3 l without replacing the filter device.
Diesel power units Skyactiv-D 2.2
According to the information provided in the manual for the Mazda 6, it is necessary to fill in original motor fluids with the following characteristics:
- Mazda Original Oil Supra DPF 0w - 30 if the air temperature outside the car is from -35 0 C (or less) to +35 0 C (or more);
- Mazda Original Oil Supra DPF 5w - 30 if the thermometer reading is in the range from -30 0 C (or less) to +35 0 C (or more);
The quality of alternative lubricants must meet the following parameters:
- according to ACEA classification - C3, with a viscosity of 0w - 30, used in temperature conditions from -35 0 C (or less) to +35 0 C (or more);
- according to ACEA standards - C3, with a viscosity of 5w - 30 is poured if the air temperature is from -30 0 C (or less) to +35 0 C (or more).
The volume of lubricant required when changing the oil is 5.1 liters with an oil filter change and 4.8 liters without replacing the oil filter.
The manufacturer of the Mazda 6 states in the manual that the use of an oil that does not meet the requirements reduces the operational period of the particulate filter; long-term use of such lubricant may result in damage to the DPF filter.
Conclusion
The recommended engine oil for Mazda 6 contributes to the vehicle's fuel efficiency and improves engine performance. According to the manual, the manufacturer selects the lubricant viscosity to ensure stable engine operation at different temperatures. It is recommended to buy low-viscosity motor oils for the winter, while thicker, all-season oils are poured for the summer at a moderate temperature range.
The suitability of a lubricant for a particular type of engine can be determined by the tolerances on the lubricant canister. In addition, when making an independent selection of motor oil, it is worth paying attention to the base fluid base; it can be synthetic, semi-synthetic and mineral.
If the machine is under warranty service, then only original Mazda lubricants can be used, otherwise the warranty does not apply to engine maintenance.
