will it mess up my car?

 

dont bother. actually if you have a reg. ignition or stock comp. you should only run 91 tops...

 

read the back of the bottle, most say they contain no lead. it won't hurt your car if it has no lead, but it won't help much either. i have seen dyno test with different octane levels of fuel, and a low compression engine (10:1 or lower) can actually make more power with a lower octane because the fuel burns faster. high octane fuel burns slower than low octane fuel therefor reducing detonation.using a higher octane fuel than is needed in yourcar also lead to carbon build up.

 

You don't have enough compression to need more than 91 octane, unless you are spraying the car or have a blower or turbo. Don't waist your money.
