Royal Purples new Max-Boost is a high performance octane booster and fuel treatment for racing applications that increases gasoline octane, reduces emissions, and enhances engine performance while stabilizing fuel. Formulated with MMT, Max-Boost delivers the best octane enhancement to help eliminate engine-damaging detonation, pre-ignition, and pinging or knocking from low-octane gasoline. Max-Boost is the best fuel system stabilizer for anyone looking to significantly boost engine performance and efficiency.
I race my car on weekends and the Royal Purple Octane Boost has been a fantastic addition. The 16 fl oz bottles are just the right size for mixing into my fuel. I’ve seen some improvements in my lap times, so I’ll keep using it for sure!

Great performance boost for my car!
I started using the Royal Purple Max Boost Octane Boost in my car and I can definitely feel the difference! My engine feels more responsive, and I love that it's in a convenient 6-pack. Just toss a bottle in and go! Definitely a keeper for any car enthusiast.

Didn’t notice much of a change
I bought this 6-pack of Royal Purple Max Boost hoping for a significant boost in performance, but I honestly didn't notice much difference after using it in my sedan. Maybe it works better in different engines? Packaging was fine, but I expected more from the hype.

Arrived damaged, but product seems okay
The octane boost itself seems fine, but I was disappointed that one of the bottles arrived leaking due to poor packaging. I contacted customer service, and they were helpful, but it was still a hassle. I guess the product works as expected, just check your shipment!
