I am looking for first hand experience in octane boosters. My engine builder says 91-92 octane. As the subject line says, my local marinas only seem to carry mostly 87. After some research, I have decided to keep some BOOSTane (Marine) octane booster in the boat. According to the mix charts, I should be able to use 1/3 ounce per gallon (one ounce per 3 gallons) to boost 4-5 boost numbers (from 87 to 91/92).
Has anyone successfully (or more importantly un-successfully) utilized this product as described?
Thanks!

seen it work for some people only needing a. little bit but I like the real thing I'm surprised your marina is not using recreation no ethanol fuel it is all 90 octane in Ohio on my lakes and is called rec fuel so no ethanol

Must be state by state (or region by region). I know there is 90+ at some marinas but the ones "local" to me Perdido Key, Fl./Orange Beach, Al. have mostly 87 (non-ethanol).

I have been using Boostane for several yrs and while I will say I would rather just have 93 it has worked for me just fine. I'm running 750 hp with carbs and really need the 93 if I'm planning on running very hard.

Thanks...and I guess you mix according to there mix chart? Do you throw in a little extra for good meeasure?

Remember, when sn ictane boostet says ‘points’ it’s a tenth.

Example: raises 5-7 points means .5-.7. 87 will become 87.5 - 87.7 .

Boostane doesn`t work like that .

I agree and learned this in my research...BOOSTane says Octane #s (not points).

SB is correct...tenth of points, not full numbers. This has been thrashed on almost every High performance site in existence.

Don't believe the hype from the snake oil.

Just go to your local FOB airport and buy 100LL and mix accordingly.

There are websites with octane mix ratio calculators.

Toluene also works. S&F has some good discussions of mix ratios.

So you`re saying that the boostane chart is false and the company is practising false advertising? How did you come up with this? Do you have an octane tester?
