Owner reviews for engine oil

When I put Mobile 1 (found a killer deal $$$) in my Golf, I noticed a bit more engine noise vs LiquiMoly. I'd say you'd be fine with both, but the nod goes to LiquiMoly if you want a very quiet engine.

I use it in my MK4 1.8T. Tuned with 212K miles on original engine and turbo. Still going strong, no complaints.

Therefore, although I have used Mobil1 synthetic oil exclusively in all my vehicles for more than 30 yrs, and even though M1 0W40 is VW 502 approved, it is not the recommended viscosity, so I now use Liqui Moly Leichtlauf high tech 5W40.

Rotella T4 15w-40 in my E32 735iL. Been running the E30 on the same oil for 6 years and the E32 for two. They both seem to like them, so I don’t see any need to change things up.

My ALH has only seen Mobil1 Turbo Diesel Truck oil. Car has 330K mile on the original turbo and still kicking.

But the Castrol Syn was good too.

My Good ol' Beast only gets Liqui Moly 5W-40. Has just 127k miles on it. it runs the best on it and is rev Happy too.

I've used Castrol GTX in my E30 for a decade now.

I use Amsoil European spec 0W20 for my '18 440i. It's engineered for vehicles requiring BMW LL-17FE+ so you know it's good

E39 S62 (M5) engine - used both castrol 10W60 and Liqui Moly 10W60.
