synthetic oil will never break down, it will get dirty and need changed but will never break down and result in engine failure. I was involved in an oil study back in the 1990's when I work for a company in Houston that builds oil drilling equipment. We tested all types of oil. synthetic oil is the best lubricant by far.
Most use Synthetic Oil.
synthetic oil
fully synthetic oil
fully synthetic oil
This truck takes synthetic 10w-40 oil i use castrol oil(synthetic blend)
Synthetic 0W30 if you can find it. If not use Synthetic 5W30
Use 30w synthetic or 10w30 synthetic. 30w is preferred.
Mercedes recommends that each of their vehicles use a certain synthetic oil. The ML350 is recommended to use 5w 30 synthetic oil only.
10w30 or 5w30 conventional , synthetic blend, or full synthetic will do
use BMW Synthetic 5W-30 oil or Mobil 1 Synthetic 0w-40 oil
SAE 10w30 synthetic oil.
look in your owners manual and see what weight oil they recommend and then get that weight oil in the synthetic oil that you like.
