octane booster

for every 5 gallons i use about 1/4 of the bottle (108 octane booster). just the regular 12oz bottle i think not sure how many ozs exactly. each bottle boost upto 20 gal i believe. works great !!!!!
 
99











99% of the octane booster out there is worthless. If you got it at an autoparts store or walmart, its junk.

no matter how much you use your not going from 93 to 104 or 108 octane. you may go from 93 to 93.4 octane but thats about it.
