Owner reviews for engine oil

I really like Castrol oil. I used the VW High Performance twice, and it was fine, but I still preferred Castrol.

Anything is better than nothing. I've tried most big oil brands but overall I like the Shell Rotella stuff most.

I use the red bottle in mine. I've found that it leaks/burns the least.

I have the VR-1 race oil on my MR2. Apparently some people said it made my car spit flames.

The approach to go with 10W40 is absolutely right - from my experience the best oil for that kind of engines! Take an expensive Castrol Magnatec Oil and it runs well.

I use the T6 as well and like it a lot. Other people in this forum have recommended in the past as it’s additives are supposed to be good the 4.0’s. Always worked well for me, it’s reputable, not the most expensive and if the additives do actually help, thats only ever a good thing.

My tuner recommended Eneos 5w40

Can't go wrong with [Shell Rotella T6](https://rotella.shell.com/en_us/products/full-synthetic-and-blend-oil/t6-full-synthetic.html). Full synthetic, JASO-MA certified and cheap.
