NEO is good for turbo motors because it has additives to prolong the life of the engine and alot of teams over in japan used it in D1 racing.

I use Kendall 5-20, because of it's low ash formula. Pricy, but the overall longterm results are worth it.

ok folks.



It's time to stop using 5W-20 folks. That **** is like water. I have a good personal relationship with the number 3 Mazda Master Tech in the country. Rotaries are his hobby. The last thing he told me was to start treating the RENESIS just like any other NA rotary. Use 5w-30 or preferably 10w-30 because the 20 will start to severely break down at the higher temps associated with the engine.
