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.

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

good product, fast shipment.

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

Tried this as an alternative toy usual octane booster and it delivered the same performance gains on the track with less volume added to my fuel. I also love that it comes with a funnel to attach to the can for mess free adding it to my fuel.

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.
