    87 octane vs. premeium is it too late!!!

    So now that i have had my first 02 2.0 for a few weeks i noticed that the car had improper timing feeling. when i got in the boost it didint pull like it should have. with that being said i now have the fear that the 87 octane i have been putting in (because i didn't put two and two together) as well as the 100k its driven before i owned the car that now am burning holes in the pistons. This forum is amazing on the things im finding out about these cars. I will certianly fill it in the morning with 93 and from here on out. My question is am i over thinking it or is there some fuel treatment i can use before i start putting in 93. I know this might sound odd but thats why im here. thanks for all your help p.s. the car is stock but didn't plan on keepin it that way

    Use 91 or higher always... if you use cheap gas you'll be knocking and loose power...

    How much gas is in the tank now? I'd just put some 93 in there as soon as you can. If it's 1/2 empty, then you should be fine just putting in 93 since you'll end up with 90. Don't bother messing with the gas that's already in there. Just don't push the car hard and drive it like a baby until you burn off the existing 87, or the 90 if you're able to fill up 1/2 a tank with 93.

    Octane booster only raises the octane level about 1/10th of a point (or so I've been told) so that would be a waste of money...

    You won't have done any permanent damage, just be sure to not do it again. Once you've gotten a tankful of proper octane rated fuel through she should be running fine. If not - you may have some other issues that are causing your condition.

    word of advice also dont go to cheap gas stations like, el-chepo, or quick stop. I would go with shell. i filled up with 91 octane before a tune and dyno, from somewhere other then shell. and the tuner asked me what gas i had in there. he told me my car was pre detanating. he told me to stick with shell.

    This is totally false information, sorry. Your local no-name gas station has brand-name gas. They just don't pay for the name so they can't advertise what they have. That's how their gas is a few cents cheaper a gallon.

    Negative sir I am correct. Go to racing trendz and ask them. Research what truckers do when 87 and 89 pumps are full and they have left over. Fact is I filled up with 91 at conaco and when they tuned my vehicle it was performing as if I had 87

    If they are doing this, they are violating the law. The division of weights and measures keeps a very close eye on fuel deliveries and distributions. Teflon is correct, no-name gas stations get gas from the same refineries as name brand, they just don't always get from the same refinery. There are only a few fuel companies that own refinerys (exxon/mobil, sunoco, BP, etc...) and these are where the no names get their fuel as well.

    Well all I can vouch for is what I saw from my tuner and how bad my car performed. Either way I choose shell. I probably got a bad batch of gas or something. Who knows

    Believe it or not they wrote me better tunes than a highly respected shop that tunes the vehicle for the pikes peak races. I will admit the shops name is cheesy but like they say don't judge a book by it cover
