do you have to pump prem. into the evo or can u pump reg.

 

pump premium if not your car will run like s**it 91-93 is the normal. Dont go below 91! My sister has a supercharged grand prix and puts 87 in it and is supose to put 93 and her supercharger is going out. So thats what will happen to the turbo.

 

of course premium only...you want the most out of your F/Ied 4 banger right? It also burns slower than lower octane gases anyways. Just turn down the boost and no more lead foot

 

I use 93 only but I made the mistake of putting 87 in once or twice

 

all i can seem to get is 91. so that is what i run, once in a while i make it to the nearest city and find 93. the more the better.

 

The Higher the better. I filled the FORD ranger with premium by accident. but never the EVO with regular.

 

in oregon you dont even get to pump your own gas, so i have never made the mistake of putting something else in.

 

93 during the week. 114 on the weekend.
