BOOSTane Premium Octane Booster 16oz, Anti Corrosion Against Ethanol, All Internal Combustion Engines, hot rods, Classics, Performance (8 Pack)

No orange tint to the plugs after 20ish tank fulls of fuel. Running 24psi on a gt40r with 93 pump fuel and boostane with 16 degrees of timing up top. I get around 97 octane with 5.3oz per tankful (14ish gal). Works great. Zero knock. Ill always run this in my limited use car.

I always run 91 octane in my 2025 Ford F-150. When I pull trailers my truck needs 93 to maintain optimal performance. That's where this bad boy comes into play as it's near impossible to find 93 octane in the Phoenix area. I mix it in with one tank of 91 and it makes it 93 octane. Magic in a bottle. F-150 truck owners should not run anything less than 91 octane.

Decent price and has kept my gen 1 Paxton coyote together with knock sensors desensitized. Haven’t needed to replace plugs or o2s yet like some mention, just gives them a “fresh off of mars” color.

Great for tuned cars

Recommended to me by my engine tuner. I have a 2008 6.2 liter gasoline HUMMER H2 with a Diablo Tune. My programmer said to run 91+ octane, which is no problem in Texas. I usually run 93 octane. We made a road trip from Texas to Alaska, all the way to Prudhoe Bay, in June of 2025. The highest octane gas in Alaska is 90 octane, and some remote places only have 87 octane (@$7.50/gallon). So this Boostane came in handy. With a 32 gallon tank, it only takes 1 ounce total of Boostane to raise the entire tank full from 90 to 91 octane, and 8 ounces total to raise the entire tank full from 87 to 91 octane. My two complaints are, number one, you can smell the fumes from even the factory sealed bottle. And it seems even with tipping the open can upside down and shaking it, it's dang near impossible to get it all out. Even after several attempts, there is still maybe 1/2 ounce left in the can. I would purchase again.

This works Great at Lake Powell, the gas pumps on the lake only have 87 octane so it comes in handy for the boat when we fill up. Our Surf boat needs 91 Octane to run good. And this was less than buying at the dock.

Felt increase in power and response immediately.

It's good can't tell if it works lol

Great product and fast delivery

The web site and easy calculator enables me to buy regular 89 octane fuel and easily increase the octane to be the same as 94ultra premium for an additional $6.00. Extra a fill up (based on adding 1/5 of a bottle of Boostane per 60 litres)Vs and extra $18.00 in up charges for 94 ultra fuel. Saving $12.00 a fill up is well worth the time. Plus my car has never performed like it does even using pump 94 Ultra premium fuel.

Work very well on my bmw m5 2019 push all the way on the powerband and you feel the car gain some timing and push better. Take 4-5oz per tank for 94 octane very good !!

Works perfectly well. But... Watch out: It is ONLY 14 OZ, not 16 OZ! Also, SIZE of the bottle is not convenient at all. The tank of my car is about 70 liters (around 15 gallons). I found that 4 oz of BOOSTane is enough to do the job. So, I have to find a way to dispense it into several portions to use it. Considering how toxic is the substance (IT LETS THE PLASTIC LIKE A JOKE!!!) it is a hassle to do this. Otherwise, absolutely recommended!

Used this on my MK7 GTI running a Neuspeed Power Module piggyback tune. Was able to use the 100 octane setting and there was a significant difference. Great product will definitely buy again.
