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

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

Liqui-Moly Molygen 5w40 every 3k-ish miles for me. I like Castrol, just prefer the LM. The quality is supposed to be fantastic.

Pros: quality is fantastic

Vehicle: Volkswagen

Mileage: 3000 km

Worry less about the now old 502.00 spec than the actual oil itself. It's API SN/CF and has MB-Approval 226.5/ 229.31/ 229.51. Even though 505.00 and 505.01 are diesel engine specs, it should be fine in your older car. One of my go-to oils is Shell Rotella T6, which is specifically for diesels, but it's a great oil.

Pros: great oil
