I told him to fill it up, he started using regular.
ended up getting 3 .11 gallons of 87, filled up the rest with 93.
should i be worried?
I'm gonna buy a 107 octane booster, in the mean time.

 

your fine...use the Lucus Octane booster.

 

You should be fine without the octane booster, just stay out of boost untill you fill up next.

 

That would make me so mad. But I guess he was trying to do the right thing and save you a little money, probably thought it was just a lancer.

 

Thats what happens when you take the spoiler off.

 

u have nothing to be worried about. use to do it all the time to save money

 

They need to look at the gas cap before filling her up

 

are you serious?

 

haha I know. What are you thinking?

 

No worries, if the ECU sees knock it will just pull some timing, but my guess is the car will run perfectly with only 3 gallons of regular in there being diluted by 93 (remember, these cars were designed to run on 91).

 

They were designed to run on 93. Check your manual.

 

Mine clearly says 91 is acceptable. Minnesota doesn't even have 93.

 

they can run on 91... look how many are in CA

but not 87..... you just cant run that crappy fuel in your car. if you cant afford premium, then maybe you cant afford an evo (not directed to the OP)

 

filling it up yourself ftw

 

well... its kind of your fault for not pumping your own gas.
