okay my car had been sitting for about 2 weeks because the radiator mest up. so i fix it and it starts up right away after two weeks of just sitting on empty i filled up the tank w/ 86 octane gas because i just was being cheap but it is killing my gas now...is it the 86 octane ? was it sitting too long? should i add a fuel treatment additive? i have both of my fans on at all times could that be it???? please help im going broke!!!

yup 86 octane gives me crappy gas milleage, ecu retards timing due to knocking.. your car is overcooling.. did you resolve that issue? overcooling causes horrid gas milleage and alot of carbon build up which sometimes can be irrepairable... fix the thermostat aand dont drive it. Use 91 octane gas. Anything lower will make your car explode! ok not explode but it makes engine knock. Mix that with overcooling .. not that good.

*edit*

when i drive her hard or well at least a little.. i get around 25 mpg.. so u may be ok?

well its rated at 23mpg from factory (which I usually get with mine) so I dont know why you're complaining when you're getting more than 23

^^ that is a very good point.

i typically get the same mpg no matter how i drive and its right around that average +/- 1 or 2 miles

hmm actualy i find that when i run 91 0ctane premium is always the best to rn good milage but its hard to find 94 in canada id so hit that up... its just i think i read befor ehat japan klze's actualy take standard liek 91 in japan im not sure what there ratings are .. but im sure if u do a search u can find the right octan level but doesnt 86 octane run a little weak im sure it can do tha tjob just not that well
