Unleash your engine's true potential with STP Octane Booster.

Review: Works for me - A bit expensive but definitely works ... I use one bottle every 3-4 fills and immediately notice a difference within first 20 miles.
Review: It works. - I usually just put regular in my F-150 5.0 and every once in in a great while I would hear that telltale pinging. My truck is a daily driver and I get a little over 17 miles per gallon After adding a bottle I can't make it ping on regular so it works as advertised with my truck. For fun one v weekend I added 2 bottles of this and 2 bottles of another brand that starts with an L to about 29gal of just bought super and 3gal of regular gas that was already in the tank. The truck ran like a beast. It would downshift sooner than it ever had and it ran better than when it was brand new. After running through all that fuel and filling the tank up with regular it took about 40 or 50 miles before the computer turned the truck back into a lazy slow shifting slacker.

### ⭐⭐⭐⭐⭐ Most effective octane booster for the money
*by M***L on September 26, 2023*

this is by far the best buy on octane boosters on amazon. I have a tuned Turbo Mazda 3 and it KNOWS when it get gas that isn't up to snuff. will pull timing and fall on its face insted of building boost. throw a bottled of this in the tank and most of the time all is well again. Ive been finding the 93 is rarely acutely 93 anymore this helps to make up the difference. the only thing i dont like is the dumb marketing on the bottle.... made from jet fuel. come on marketing team...
