Not even sugar based ethanol? what about the hydro fuel cell? I was reading about this one company who makes them for various cars. I hear it's a direct bolt on process. Also I was curious if it's possible to run Biodiesel in our cars. I was watching this show where J-Lenno showed a concept for a car with a jet engine in it running on biodiesel. Since our cars use aviation technology I was curious if it's possible to make a conversion. Also has anyone heard the news about the RX-9 Hybrid? crazy...

The owner's manual says up to 10% is fine. I think almost all gas has 8-10% nowadays.

More will damage your fuel system, as mentioned, unless you upgrade the sensitive parts. Even then, you can corrode the inside of your engine with ethanol.

And yeah, stick with regular gas, not premium. Premium is 100% useless in your engine and it will leave more gunky deposits. The only thing special about it is that it is required in certain engines, especially high compression or high boost engines. While those engines may be high performance, putting premium in a lower compression non-turbo is a total waste. Even the turbo model doesn't need it at factory boost levels.

I see... Interesting... What about a lower octane? Like 86 or something?

Ultimately, the answer is you want to run the lowest possible octane that can still be used in your vehicle without risk of pre-ignition. Higher octane fuels dont posess any magical power enhancers, they just have a higher resistance to pre-ignition. Basically, you can compress them more untill they auto-ignite. Great for applications like mine where I am stuffing 25 pounds of boost down the motor, unnecessary for stock vehicles.

Also, dont get too hung up on numbers unless you are sure of what you see. Some are RM/2 and some are RON. Make sure you know what the number REALLY means.
