How To Boost Octane From 91 To 93
If you’re on the West Coast, where 91 octane is the highest pump fuel available, running a vehicle designed for 93 octane can be a challenge—until now. BOOSTane Octane Booster provides an affordable, easy solution to achieve 93 octane and maximize your engine’s performance. Here’s how to use it:
- Step 1: Check your tank's fuel level and consult the BOOSTane mixing chart (on the can, our website, or iOS app) to determine how much BOOSTane you’ll need to achieve 93 octane.

Step 2:
-
If your tank is empty: Pour the recommended amount of BOOSTane into your tank first, then refuel. This ensures seamless blending.
- If your tank is already filled: Add BOOSTane directly to the tank, start your engine, and drive normally. Your fuel will naturally mix as you go—or activate your fuel pump if applicable.

Step 3: Drive with confidence, knowing you’ve upgraded to 93 octane.
