    High Octane Gas / Octane Boosters

    Guys i was wondering if any of you have used octane boosters or high octane gas (petrol) (racing fuel)

    In South Africa, they sell 95 lead free at the pump and 95 lead replacement.

    I currently run 95 lead free, i was thinking of adding an actane booster (eg. toulene or NOS octane boost racing formula), which will bring my actane level to 102. (racing fuel equivalent)

    Do you guys recommed this ? will it cause damage ? any opinions ?

    Unless your motor has been modified with high compression and/or porting, you will not benefit at all from running higher octane. If your motor is stock, it will run better on regular unleaded. The higher the octane, the slower the burn of the fuel, which helps control detonation. Running high octane in a stock motor will do nothing good for performance. If you were to run 102 or something like that in a stock motor it would probably hurt performance. Because of the slow burn of the fuel, the motor would actually run too cool.

    Higher octane on a stock motor won't help. It will in fact make you lose power.

    So basicly, don't run it if you don't need it. You would need it if you had a high compression or advanced timing.

    8 sided

    Octane is an 8 sided carbon atom which deters flame burn. The trick is to get the proper amount of octane not too much or too little. I run an equal mix of 89 & 92 with 150 lbs of compression
