Royal Purple's 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. Review: I’ve been running the Lucas Oil octane additive for years and thought I’d treat myself to this after what seemed like declining returns from the Lucas in my pickup. After two fill-ups with Royal Purple additive I’m kicking myself for not investing in the right product long ago. At ~4000 ft above sea level, my manual transmission supercharged Tacoma feels like a different vehicle: better throttle response, less engine noise, and better economy AND no more residue on my tailpipe to boot. Driving in town isn’t such a chore anymore and turning it loose is that much more enjoyable - if you’re looking at this and are using Lucas’ additive try it and I bet you’ll be impressed too. Review: I use this in the gas tank of my 2017 Toyota Land Cruiser with every fill. The car runs better & I have had no major mechanical issues. The gas mileage, while not good, is better when I use the Royal Purple 11757 Max Boost Octane Boost.

I haven't used it yet but I'm sure it will be fine. Royal Purple is a well respected brand. I need it for my scooter (moped) as I have REC 90 gas available but the scooter store recommends 93 octane which has ethanol and I don't want gas with ethanol. This will solve my problem. I'll put some in my car from time to time to keep the engine clean and performing well. 1 can would last for several years with the scooter, they get 100 MPG and I only ride it locally.
