Anyone now of anything like that
But even then why use it? Just buy 93 or 91 octane gas and don't spend $20 on a octane booster.Most/All of the octane boosters you get at places like AutoZone that say they raise the octane by 5 points really mean .5 or 87 will be raised to 87.5.
The Torco costs about $20 for a 32 oz bottle and it takes a whole bottle to raise a 20 gal fill from 87 to 91.
When I brought the subject up months ago because we here do not have 93, you advised me NOT TO DO IT, and the reasons why, I have not forgotten.Beware using any octane booster that contains MMT (most do).
It will coat your spark plugs with brown residue deposits, and is also not good for your cat or O2 sensors.
Avoid long term use, and only use it in emergencies when you cannot fill up with the correct grade of gas (especially if you've tuned your EB).
