Works as advertised.
Works to boost the octane of stale fuel. Also works for cars that require higher octane for use. I have a super charged svt cobra that requires 95 octane . I use the booster to raise the octane fuel for maximum performance.

Snowmobile booster
I use octanium to boost my 91 to 93+ octane for my snowmobile. I had great luck with it last year, no pinging or check engine lights and the sled rips!

STAINED MY TANK!
Stained the stock tank on my 2022 Husky TX300i woods race bike. Cant see where my fuel level is now unless i take the fuel cap off and slosh it. Noticed this the first time i ran the Madditive. See my pics... VP i like your stuff but not if its going to harm my factory equipment...

best for stock engines!
I did not know about this product until I saw some reviews about it and had to try it myself. One thing for sure is that it will change your perspective about your vehicle once you drive it. For me It did change on how my car was from before I did not use it to now for every fill up I get on gas so in short it is needed for my car for without it does not have that different feeling and now I use it in my car, it feels alot different WAY DIFFERENT! So thanks VP Racing for making this product and making my car alot more fun to drive!
