With that in mind, it is easy to understand that an oil with 5w in the rating will offer better low temperature performance than an oil with 10w in the rating. This is because, regardless of their viscosities at operating temperature, 5w oil will always be thinner than 10w oil.

I just chenged my oil yesterday and the oil and filter were about $38 together al WalMart. Delo was the oil brand and Fram was the filter brand.
There is a difference between 10w40 motor oil and 20w40 motor oil. However, there are not many differences at all. So let us get to know the differences between 10w40 motor oil and 20w40 motor oil in terms of viscosity, fuel economy, and hot weather. Viscosity. The 10w40 motor oil means that the 10w meant winter. It means that the motor oil
10w-30 VS. 15w-50 oil? I read on the back of the Mobil 1 quart of synthetic 15w-50 that is better for turbo and supercharged cars. It is thicker, so it can handle the extra heat better. in my case, my motor is a EJ22T and has 107k, whereas you might not want to use an oil this thick on a newer wrx with alot less miles.
Only use this chart to find an oil equivalent to the manufacturer’s recommended oil for your tractor or truck. You may notice that ISO 46 can replace both 15W and 20W SAE oils. This is because the ISO specifications are broad, and they overlap with SAE weights in some cases. If your tractor or truck calls for 20W hydraulic oil, it may be best
The 10W 40 oil is thicker and is thought by many to be more efficient. 15w40 is thicker at all temps vs 10w30.
