Would filling up on 1$ octane booster work? lol gas prices over here are 3.15 it would take me 81$ to fill up and that what is the cheapest and easyest mod there to help mpg? Would a 19$ muffler from autozone + 15$parts help over stock? its a turbo muffler damn gas prices are driving me nuts im thinkin of buying 2 mopeds

 

Octane booster doesn't work. The money you spent on a muffler and accessories would negate the small small gains if you had any over time.

I had a dream of a moped last night.... I like them more and more as the days go by...damn gas prices!!

 

I thought some of those octane boosters might not be too good for the oxygen sensor??
