<![CDATA[Is there a mind boggling difference between 89 and 91 octane?]]>Place I normally goto to fill up, Clarks on 8th st in Moorhead, has 89 octane for sale for like 60 cents cheaper than 91 octane.

I usually put in 20 bucks for everytime i fill up with gas but normally cant to the full mark without goin over 20.

I've put in 91+ the entire time I've owned my car, better part of 5 years, and I dont know, I hardly ever push the car to its limits, so what're the reprecussions if I decide to fill it up fully for 20 instead of leaving a qtr. of a tank left empty?

aka will I die?

But ya, nothing lower than 91 on a turbo engine. Youll notice the loss of power instantly and may even hear ping on accel.

Just sell your turbo kit or swap it with someones stock sti stuff... And I speak on behalf of everyone..
