Default Fuel octane additive ??

When traveling and you can't find 91 octane fuel, what octane additive actually works and is recommended for the 1540 engine?

acetone is reported to work well and require less than an oz for a full tank. i have used it with great results. about $15 a gallon.

Harley sells a fuel additive for exactly this purpose.

Not sure how well it performs, but I hear it works well as a paint stripper.

I never found an octane booster that did anything except waste money and foul the plugs. But if keep compression below ten to one I have been able to run 87 w/o any significant problem that a little more fuel would not solve.

Acetone is not an octane booster, it's a solvent. At best it will clean your injectors, at worst it's highly corrosive. Use what the pros use - toluene or xylene in 10% concentration will raise your octane from about 91 to 94. Don't wast your money on store-bought octane boosters, when they say they raise your octane by "several points", they mean from 91 to 91.4.

Toluene or xylene cost less than 1/2 as much as LUCAS NHRA OCTANE BOOSTER. And they are easily carried in MSR 33 oz fuel bottles that you can buy at any camping store. YES I AM A CHEMIST!
