    I'm going out and playing in the dunes this weekend and was thinking of throwing some octane booster in the tank when I get out there. Are there any negative affects of using the stuff even just for one tank? or any brand recomendations?

    There shouldn't be any negative effects but there shouldn't be any reason you should throw it in your tank either.

    I used to run VP Red in one of my old scooters, but that was only because I had 13.5:1 compression. Higher octane makes for a more even detonation which is critical when you have one giant piston with little to no extra room on the combustion chamber...Now, on a big ol V8, I don't know what the benefit woudl be...also, the problem with the additives is that to got from 91 to 105 octane meant I needed to treat a LOT of fuel, adn it was no inexpensive. You gotta figure the water down figure would be HUGE on 20 + gallons of fuel...in othe rwords, you woudl need a lot of additive for just a little return.

    I don't really need it I thought I'd just play with it and see if it helps the truck run a little better. The sheet on the motor recommends 98-102. and like mentioned in california all we get at the pump is 91.

    what comp. ratio you running? Are you planning on having your foot in it a lot?

    Posted the same time as me.......
    It looks like with that recommendation you must be 10.5 or higher, is this a street motor?

    octane booster has nominal effects on a full tank of fuel... "increased by 5 points" "treats up to 20 gallons"

    means it ups the octane .5 over 20 gallons... so you'd need what, 20 bottles for 10 full octane points on 20 gallons? and at 6 dollars a bottle? 120 bucks? just buy some racing fuel.. find a speed shop in your town or on your way out to the dunes..

    You're better off to get a little VP racing fuel and mix it into the tank of fuel. Also as far as octane booster, it takes more and more of it to get the next increase. Kind of inversely proportional. The first can gets you a 0.5 increase in octane rating, the next can a 0.4 increase, the third maybe a 0.3 increase etc.

    Your octane boosters like hot 104 are just petroleum waste products mixed with kerosene packaged in a pretty bottle.. refiners have to do something with the leftovers from refining gasoline, and hazmat is too expensive, so they sell the waste to companies called converters ( STP is the biggest).. if the stuff was any good, why not leave it in the gasoline to begin with?

    As has been said, the octane increase is minimal, but the other downsides are btu loss ( from the lower energy kerosene ), metallic deposits and emissions you get when the mmt is combusted.. oh yeah, you'll also get a sticky sooty residue that does wonders for ring sealing and your cylinder walls.
