Icemark,

I know its not necessarily FC specific, but its good info. Can we at least archive this?

 

if you want better performing gas get race fuel. pretty much anything that has lead in it. Leaded gas is better, it lubricates alot better. i have never ran it in a car let alone a rotary engine but have ran it in all my dirt bikes and four wheelers. it doesn't just make a high comp. motor run better it made my 22 year old un rebuilt beat to **** xr250 run 10 times better and feel more powerful. but very expensive. Something like 3 dollers a gallon for VP red. http://www.vpracingfuels.com/vp_01_f...D8023427AF40B5
check out the site it will tell you about the fuel and what it's best used for. good stuff

 

dont run leaded if you still have cats!!!

 

OK I've read all of these posts but they don't seem to mesh with my personal experience. I have an 89 na with a streetport and notice a rather large difference in idle quality and overall motor 'happiness' with the silver vs. the low grade gas. Could this be becuse of the porting, if so why?
