I would advise against using methanol as an octane enhancer. It’s corrosive and has a much different stoich than gasoline.Just keep this in mind if you’re considering adding an octane booster. From the Users Manual:
- The use of fuel additives, which are now being sold as octane enhancers, is not recommended. Most of these products contain high concentrations of methanol. Fuel system damage or vehicle performance problems resulting from the use of such fuels or additives is not the responsibility of the manufacturer and may void or not be covered under the New Vehicle Limited Warranty.
Boostane has proven to be extremely effective and I saw no ill effects, nor have thousands of others who use it. I did notice the electrodes on the spark plugs were orange, though I didn’t experience premature fouling, though suspect there may have been some reduction of spark plug life longer term.
