will octane booster work

Okay i cant find any 93 in my area so i was wondering if i buy 91 and add octane booster if it would be okay. i have around 185-190 compression. if so what kind of octane booster is the best?

You'll be fine with 91 octane gas.

I ran an engine with single cooling, 3 degrees advanced timing and 205 lbs compression on pump gas for years with no signs of detto.

Octane boosters are garbage and will only drain you wallet and disintegrate your expensive exhaust hose over time. Avoid them at all cost IMO.

I found some 94 on sunday, filled my turbo 626 with it and got 29 mpg where i usually get 23-25. I am going to see how my ski likes it this coming weekend.

Is there any way to boost the octane cheaply (i am thining about my car....i dont want to put additives in my ski)???????

the adative you should be looking for is "tylene" (not sure of the spelling). that is what the smell is whenever you smell race fuel. it is also what is added to race fuels to increase the octane rating. so if you use a booster look for one that has tylene in it.

Mindful of the evil reputation of octane boosters in general, toluene is a very safe choice because it is one of the main octane boosters used by oil companies in producing ordinary gasoline of all grades. Thus if toluene is indeed harmful to your engine as feared, your engine would have disintegrated long, long ago since ordinary pump gasoline can contain as much as 50% aromatic hydrocarbons.

Toluene is a pure hydrocarbon (C7H8). i.e. it contains only hydrogen and carbon atoms. It belongs to a particular category of hydrocarbons called aromatic hydrocarbons. Complete combustion of toluene yields CO2 and H2O. This fact ensures that the entire emission control system such as the catalyst and oxygen sensor of your car is unaffected. There are no metallic compounds (lead, magnesium etc), no nitro compounds and no oxygen atoms in toluene. It is made up of exactly the same ingredients as ordinary gasoline. In fact it is one of the main ingredients of gasoline.

Toluene has a RON octane rating of 121 and a MON rating of 107, leading to a (R+M)/2 rating of 114. (R+M)/2 is how ordinary fuels are rated in the US. Note that toluene has a sensitivity rating of 121-107=14. This compares favorably with alcohols which have sensitivities in the 20-30 range. The more sensitive a fuel is the more its performance degrades under load. Toluene's low sensitivity means that it is an excellent fuel for a heavily loaded engine.

Toluene is denser than ordinary gasoline (0.87 g/mL vs. 0.72-0.74) and contains more energy per unit volume. Thus combustion of toluene leads to more energy being liberated and thus more power generated. This is in contrast to oxygenated octane boosters like ethanol or MTBE which contain less energy per unit volume compared to gasoline. The higher heating value of toluene also means that the exhaust gases contain more kinetic energy, which in turn means that there is more energy to drive turbocharger vanes. In practical terms this is experienced as a faster onset of turbo boost.

Chevron's published composition of 100 octane aviation fuel shows that toluene comprises up to 14% alone and is the predominant aromatic hydrocarbon. Unfortunately composition specifications for automotive gasoline is harder to pin down due to constantly changing requirements

I agree that there are a few additives out there that can stabilize or make the octane rating go up. I was referring to most of the crap that is sold in chain automotive stores that has a flashy label and a high price. Many of these contain MMT which can damage rubber parts over time. Personally I have been buying Citgo 110 by the 55 gal drum or I can get Renegade 110 from a local pump.

how much a gallon for the sunco 110?? Ive got VP fuels at work,just looking to compare the two.

I pay $7.50 a gallon for the Sunoco 110 at the pump here in town. I mix it half and half with Avgas 100($5 a gal.).
A month ago the Sunoco 110 was $5.95.:rolleyes: f'n bastards...

Displacment and high compression are fun!
Alot of power tires you out faster, so its all good IMO!:bigok:
