type of gas to use

SideWinderGX · 03-16-2007, 02:05 AM

i was reading to owners manual...and, i dont remember the exact words, but it went something like: unleaded fuel only, unleaded 87 can be used, however for added performance you may use unleaded 91. can i mix both of those fuels? i believe 87 is in my tank. well, i put in 87 last time, so its in there now. will 91 octane have any negative effects on my spark plugs or anything else? i know itll give me better performance but im just not sure if itll mess up anything, or if its worth it. thanks!

This is an age old topic. I'm not going to get into it but to answer your question, no it will not hurt anything mixing 87 and 91. If you want to know I use 93 everytime I fill up, even when gas is above $3 a gallon.

sorry. and thanks.

search button is my friend? :P lemme go try to find some topics on it then. you use 93? manual doesnt say anything about 93...it wouldnt hurt my stock 20 year old engine at all?

Why are you sorry? I didn't mean to sound angry. I guess its just the way I come off.

Nope, 93 will not hurt anything, 87 on the other hand could, and I emphasize "could".

i know, your a rational guy, i didnt think you were mad. its just i dont like repeating topics that i couldve found elsewhere.

really? didnt think 87 would hurt my car lmao. ill drive down to byrne dairy when my car is registered and fill it up with 93 lol. big performance difference? although ive driven it twice so far, i dont think ill know the difference between the two.

93 octane just reduces the chance of detonation. I just use it as extra insurance. Turbo motors tend to detonate on 87 (if you boost the crap outta it like me). And detonation will ruin any motor in no time.
