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.

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

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.

Works as described! Satisfied customer, thanks!

Motor cycle I’m still not to sure, I haven’t rode it that much 🤷🏻‍♂️

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.

Checked this product out very carefuly as most Octane boosters are only so so at best. Lots of independant reviews say it's good. I have been using it to boost the local 91 to 98. 91 is the minimum for the car and 94 is just nit available outside of Toronto or Montreal in my area. So does it work - YES! The car is perceptibly more responsive and accelerates far more smoothly.

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!

Great product and fast delivery

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 !!
