Do the octane boosters work?

Very few engines need more than premium gasoline. You may want to fill with premium the tank before your night out as well as your night out-to give the computer a chance to adjust timing to the new octane level.

IF you need more than 92 octane, most octane boosters are repackaged toluene/xlyene (which you can buy at paint stores by the gallon cheaper than at autozone by the ounce).

I like to mix 1 gal "octane booster" with 1 gal gasoline in a 5 gal can before dumping it in the tank and filling up (this helps mixing and keeps the undiluted chemicals away from hoses/paint etc.

Every time I work out the costs, I cannot make low grade gasoline into 92 octane cheaper than buying the 92 octane to start out with (except for using low grade gas with a water/methanol "on demand" injection system)

Manganese based octane boosters do seem to work and do cause orange-brown deposits with some minimal effect on the catalytic converter and O2 sensors. Seem to be best suited to a "once in a while" type of use.

lol I posted that link several months ago (march/april), but the threads got closed for some reason; some moron (you know who you are) thought I was advertising for some chemical company. :rolleyes:

but I've been using it ever since, with no problems. I also have xylene, but use that mainly for other chemistry applications (extractions, isolations, etc.), I just fuel up with 89.
