It's become popular to use methanol/petrol mix these days especially with those with multi-map facility. The popular mix ratio seems to be 20%
Are there advantages of using much lower concentrations say, 3-5% as you might with an octane booster, without the need for any map adjustment?

I`ve also heard of people running up to 5% in with the fuel as an alternative to octane booster,although im not 100% certain if this is safe or even a good idea or not mate,tbh i think this subject is best left to one of the mappers/specialists on here to give there thoughts on it,be patient buddy and someone will come to your aid shortly.

 

I believe I read about running sub 5% as a booster also

 

Methanol as Octane booster I wouldn't use,just due most common ingredient of the Octane booster is,MTBE, ETBE,Ethanol or Toluene

About the octane boosters and fuels great post

Methanol lowers the calorific value of the fule, without mapping it will kill your engine.
