Top 10 Nos Octane Boosters
for October 2022

Octane boosters are an extremely popular product in the automotive industry, and while they're commonly used as fuel additives, they're also used for a variety of other things, from adding horsepower to cleaning engines. Octane boosters are designed to enhance the performance of gasoline, adding octane, which is a measure of how clean a fuel is, to the fuel. Octane boosters, also called octane enhancers, are formulated with chemicals that increase the octane rating of gasoline.

In the Different Guide , we test octane boosters on performance, including engine performance, acceleration, and fuel efficiency. We also evaluate ease of use, including how easy it is to add the octane booster to your gas tank, as well as how easy it is to use. Our top pick is the STP 91 Octane Booster, which received the highest rating for performance, ease of use, and value in our lab tests. We also tested a variety of octane boosters, including STP's 91 Octane Booster, Amsoil's 99 Octane Booster, and Seafoam's 87 Octane Booster. Here are the best octane boosters you can buy in 2022:
