Hey hawaii,

your savings on 20 gallons of regular would be $4. Each bottle of octane booster costs $8 to $10. Despite their advertising, no octane booster on the market, when mixed at the ratio recommended on the bottle, will raise your octane from 87 to 92. Most of them will raise the octane 1 to 3 points.

Have you tried running your car on lower octane fuel without octane booster? Tell me about your car & engine.

Have a safe & enjoyable Labor Day Weekend.

The car is still enroute from the mainland and should arrive in a couple weeks. i will try running less octane and see what happens 1st...maybe it will be fine.
It has a Boss 351 block and heads built by Hall Pantera to Street Brute specs, roller rockers, solid cam and 760 Holley carb.
If your engine doesne't knock when accelerating you don't need additioal Octane. My car has a compression ratio somewhere around 11 to 11.5 to one and it still knocks with 100. I have tried boost and it does not seem to make any difference. Also it is vary hard to mix the boost with the gas in the tank.
I've never found an octane booster that did any good for my engine after its last overhaul - 10.5-1, 2v quench heads & I still had pinging at WOT. Finally, bought some 110 octane racing gas & mixed it approx. 25-30% with 91 octane pump gas. Instantly solved my pinging problem & completely stopped the occasional run-on I was experiencing - car really loves this mixture! The Sunoco 110 I get for $5.25/gal hasn't changed in price for the last year & the distributor tells me it doesn't go up in price when the regular octane pump gas does - go figure?? Sometime in the future I may change out the head gaskets to something thicker to drop my compression a bit but for now I like the performance I'm getting. YMMV.

My experience has been that Av gas (Airplane fuel) is the way to go. Last I saw the 110/130 was about 30 cents a gallon more than automotive grade premium yet is formulated to be stored much longer without ill effects. Of course in can't be legally pumped into a road going vehichle since is not road taxed..........but tell them it's for a boat. I recommend you get to know say, a helicopter pilot who could hook you up.
