I'm using Castrol GPX 5W-20, non-synthetic (per Mazda's recommendation).

There's a lengthy, ongoing debate about what kind of oil to use. Some like non-synthetic ("dino"); others believe synthetic is better. And to further complicate things, Mazda recommends 5W-20 in North America and 5W-30 everywhere else. Search and you'll enjoy countless hours (or days) reading about the RX-8 and oil.

what kinda sick #$%^ are you?

Either that or you just simply made a substantially bad financial investment on a dead animal carcass.

at any rate, it makes references to searching.
