We have mineral oils, part synthetic oils, full synthetic oils, 0w20, 0W30, 0W40, 5W30, 5W40, 5W50, 10W60, 20W50 oils. We have approvals from different brands for different oils for different engines. So, let's break all these down and make everything simple for everybody. Oils have 2 viscosities - one at cold - 0W, 5W, 10W and one viscosity at 100 degrees Celsius. The principle behind all this is pretty simple - the oil is pretty thick, and as it runs through the engine, it heats up, and its viscosity decreases. As viscosity decreases, oil pressure decreases. At some point, if the oil is too thin, or too thick, you don't have enough lubrication. And here is a real world example - Subaru recommends 0W20 for the BRZ. It's a thin oil which will save you fuel, it will start at any temperature because it's thin, it's a 0W oil, and if you drive it in normal conditions, it's just fine it's great. Keep in mind, the BRZ has a 2.0 NA engine which produces 200hp or 100hp per litre. The BMW M3 e92 has a 4.0L V8 NA engine which has 420hp or 105hp per litre, which is pretty close to the BRZ in terms of power per litre. BMW recommends 10W60 oil which is a thick oil. Why? Because they know that this car will frequently hit redline at 8,000 rpm, and it will be driven in severe conditions, on a race track, drifts, etc. 0W20 Mobil 1 at 40 degrees C the oil has 44.8 cSt at 100 degrees C the oil has 8.7 cSt 0W40 Mobil 1 at 40 degrees C the oil has 75 cSt at 100 degrees C the oil has 13.5 cSt 10W60 Castrol Edge at 40 degrees C the oil has 160 cSt at 100 degrees C the oil has 22.7 cSt The 10W60 would probably have around 10 to 13 cSt at 130 degrees C in racing conditions, and that's the main reason why it's recommended for the M3 e92. If you take the M3 to Nurburgring with its 10W60 oil, no problem. If you take the BRZ to Nurburgring with 0W20, you are pretty likely to destroy the engine. Engine oil temperatures will get as high as 135 degrees C. The 10W60 will be fine, but the 0W20 won't. It will be like water - no oil pressure, boom, no lubrication. Engine oil temperatures, on average, vary from 90 to 105 degrees C. On a racetrack, they get as high as 140 degrees C, so we need a stronger oil. On the other hand, if you try to cold start the M3 at -30 degrees C with the 10W60, you won't have lubrication. The oil is way too thick. M3 owners who live in extremely cold areas should be using 0W40 during winter and 10W60 during winter. The BRZ with 0W20 will start at -30 C without a problem without damaging the engine. Now, let's make a quick summary. No matter what car you have, you don't need just one oil. Manufacturers recommend the one that saves fuel and helps the car run properly under normal conditions. Now, normal, has many meanings. Racetrack - thick oil - like a 5W50 or a 10W60 Cold areas - thin oil - 0W30 or 0W40 Fuel saving - thin oil - 0W20 or 0W30 Average driving, average temperatures, not too extreme - an average oil - 5W30 The most frequently recommended oil is 5W30, and that's because it fits most needs, but not the extreme ones. So basically, each specific oil satisfies something. It depends on how you drive, what you drive, where you drive, and what you do with your car. So, let me know in the comment section below if you have any other questions about oil viscosities, I also have 2 videos on using the right oil for BMW and Audi, so if you own a car from Volkswagen Group or a BMW, go ahead and watch those as well.
