Premix your 8, get better gas milage

[Chibana]

There was a post over at another RX-8 forum that this issue is true when using many different kinds of oils that were not designed for pre-mixing in rotary powered cars. Idemitsu claims that fouling is common among people who use these oils, but that they have never heard of this issue happening with anyone using their pre-mix oil. Of course, they have a monetary reason to say that, but I also suspect it's true. I see an awful lot of people using ordinary two-stroke oil and such as premix, and it seems foolish to me. If you're going to do it, use one that's designed for the purpose, and has a lot of racing experience to back it up.
