gas in oil?
After I got my new motor last year, I ran 93 octane all the time until my mechanic at the mazda dealership told me that I had gas in my oil because my car wasn't burning the 93 completely because it had more chemicals and **** in it than 89. So he says put 89 in it so I have ever since and never had gas in the oil again. But now I have an intake, dp, and cb so I figure I would try 93 again but the same thing happens, any suggestions on this, do I need an upgraded ignition or something???

Always use premium in turbo cars. 89 is too volatile to be used in high pressure situations. And never use 89 in 3rd gens. Dun worry about the gas in the oil, do oil changes more frequently if u are still worried. Its cheaper to change oil than rebuild an engine

Sounds to me like your mechanic wants you to blow your engine so he can rape you over the coals! Turbo cars (actually, any hi performance vehicle) needs the added octane to reduce the likelyhood of detonation. With 89 octane and high boost, high intake air temp, etc, the likelyhood of you popping an apex seal is greater than if you use the higher octane. As for the fuel in your oil, it is fairly common, but if you have alot you may have leaky injectors. Just make sure to change your oil every 2-3 thousand miles.
