Owner reviews for engine oil

Last oil change (Sep 2022, 100,094 miles), I used Castrol Edge 0W-40.

I run Amsoil in both of mine. Also use all their gear oil and transmission fluid

Better to use cheap oil and change often than to buy expensive oil and run it out to 10k+ miles. Personally I typically use Castrol products and change my gasoline engines at 3k and Diesel engines at 5k miles.

Pennzoil ultra platinum. It is what they put in it from factory and it is one of the best oils around next to amsoil for a lot less money.

Put 100k miles on my mark iv jetta tdi while using the stuff. No problems.

I've used T6 in my MK4 BEW for 5 years now. Regular changes, no issues at all, and at 1/3, the cost of 'suggested' brand.

I use Fuchs Titan SuperSyn 5W-40 - widely considered to be the lowest-consumption oil for the M54 engine, and it's very cheap.

Mann filter.

5w40 liqu moly all the way leichtlauf high tech

I run 5w-40 in my veloster (2012 w/ 140k miles). An engine with that many miles has greater parts tolerance than it did when new.

After not being very impressed with Amsoil 5W-30 after a 5,000 mile oil analysis, I'm going to see how this stuff looks after 5K.
