Torco Accelerator. I've tried it all and this is most convenient, cost effective way to run high octane. Little over 2 oz./gallon to raise 93 pump to 100 octane.

 

DO not exceed 30% toluene to gas (no lube needed)

 

Toluene for sure. Just got the evo but I ran it in my Lightning for 50,000 miles. I use an ounce of Marvel Mystery Oil with each gallon as a lubricant. What people don;t realize is gasoline is 30+ percent toluene to begin with.

As for price, shop around. With a little work you can find it for around $5 a gallon or perhaps a little less. You may have to buy it in a 5 gallon quantity. Paint stores or chemical supplies are the places to look.

If you add Toulene, just make it 10% and then add an OZ of "Marvals Mystery Oil" for lubricant. With 93 octane you will have way over 100Octane.


Don't forget people. If you car is tuned for 93, and lets say you pump in 104 octane. your car will more then likely be slower or the same as it'll now be excessievly rich. It may be smoother though. So turn up the boost at least.
