I have a 93 stock except for exhaust . Has about 36 k on it
I keep it in SC
I havent checked the timing , I believe it is whatever came stock .
Id like to know what gas I should be using
I have been using 93 , dont know why just have
Should I switch to 87 ? Does it make any differance ?
W stock timing, I run 87. Putting 93 in it doesnt hurt it, but you're not gaining anything out of it
If it's not tuned for 93 octane, I would just stick with regular. You'd just be wasting money, IMHO.
87. no need to spend the extra money in fuel that doesnt improve much. and btw. if thats your car. then damn good buy.
