Here in California we get this crappy 91 octane gas and have to detune our cars to accomodate it. If I throw a bottle of 104 octane booster in with each tankful of gas, can I safely kick up my timing without fear of detonation?
Which is why using Octane Boost is a waste of money IMO. We discussed this in a thread a year or so ago. The general concensus was that to gain an appreciable increase in octane you'd have to spend more money on Boost than you would probably find practical. Adding one bottle to a tank of gas isn't going to do much of anything.MidLifeC said:You would need 1 gallon of 104 octane booster per 4 gallons of 91 octane gas to arrive at a mix of 93.6 Octane. How much do those 12 oz bottles cost?
Good post. I should have read it before posting mine comment above. You said it a heck of a lot better than I did. ;-)WDW MKR said:If you want reasonably priced octane booster that actually works, buy some pure Xylene from your local hardware or paint store. It has an effective octane rating of 114-116. You will need to mix in a few teaspoons of Marvel Mystery Oil to provide lubrication to the injectors and pumps, since Xylene is so dry. You can also use Toulene, which has a slightly lower effective octane rating. The Turbo Buick community has a lot of information on xylene at www.turbobuicks.com . A 1:3 ratio, xylene to pump fuel, is a pretty good mix that nets 98-99oct. A 2:3 ratio can net you 101-102oct, but that's a pretty strong mix. If you're worried about the effects of xylene and/or toulene, just look up that composition of race fuel... xylene and toulene are what provide the bulk of the octane boost.
The bottled boosters don't work as advertised. They can effectively raise the octane rating of a full tank by less than a full point. Very expensive option if you want to actually raise is by a few full points. The stuff that Jim Bell recommends is NOS octane booster. According to the Summit website, a 12oz. container of this crap raises the octane level of 12gal of fuel by 4-7 octane points! People assume they mean full points, when they really mean 0.4-0.7. For 12oz. of anything to raise the effective octane rating of 12gal of 93oct fuel, the booster would need an effective octane rating of 609! The street version of NOS booster is only good for 2-3 points, as in 02.-0.3 octane points.

If you want better results get Torco fuel concentrate, I have been using 2 cans of 32oz on a full tank of 91 octane on 21psi and no problems. It really works.
