My preferred is Amsoil 10w30, the good stuff. Seem to burn less of it off when driving hard.

Pros: burn less oil

I would recommended shell ultra 15w50 . KV100 is 20 which is thick as fuck and won't shear down quickly. Mogul 7100 is thin and will shear down to 40 grade and internationally considered garbage oil. Shell is made of group 3+ base oil so its going to perform better.

Pros: performs better

Cons: shears down quickly

It’s probably placebo but I feel that I burn less with Amsoil. That said with current prices I’ve gone back to my default of Castrol.

Pros: burn less oil

Vehicle: Honda S2000

On an old e36, 5w30 full synthetic no matter the brand would often cause some leaks. Switched to some thicker Rotella oil made for diesels and suddenly no more leaks.

Pros: no more leaks

Cons: caused some leaks

Vehicle: BMW
