Re: FS/FT 1986 Mazda Rx7 FC3S
I don't trust you because I have read the manual and you obviously have not. Anything more than 87 octane on a stock FC motor actually is more likely to cause problems, and will actually result in less HP.
See the octane rating has absolutely nothing to do with BTU or power output. The only thing higher octane numbers do, is make it harder to pre-ignite. It makes the burn slower. Higher octane does not contain any additional power or performance unless the motor was designed or tuned to run on a higher octane (and even then the additional power is only a result of higher compression or boost along with computr processing).
In fact (more so on a non-turbo) you want the gas to ignite as easy as possible. Lower octane on a rotary with less than a 10:1 compression actually burns cleaner and faster than a higher octane.
So using higher octanes on a stock motor will result in increased deposits on the rotor faces(which could result in pre-mature engine failure), less power, and less money in your wallet.

Re: FS/FT 1986 Mazda Rx7 FC3S
how do u think u can tell me what makes MY car run better....r u behind the wheel.....NO!!! just because its ur belief that 87 makes the car runs better doesnt mean its true....premium gas is a big controversy with rotary engines.

homie any real rotary owner knows premium is the way to go. ask anybody with a decent rx7 if they put shitty gass in it and c what kinda awnsers you get. stock or not rotarys are way diffrent from a regular engine.... lets just say they got a taste for premium
