Royal Purple Max-Boost – 16 fl oz Can is a high-performance octane booster with fuel treatment that increases gasoline octane, reduces emissions, and enhances engine performance while stabilizing fuel. Max-Boost is formulated with MMT, which delivers the best octane enhancement to help eliminate engine-damaging detonation, pre-ignition, and pinging or knocking from low octane gasoline. Max-Boost is formulated for engines equipped with carburetors, port fuel injection and direct injection, as well as turbocharged, supercharged and nitrous-injected engines. Safe for use in leaded and unleaded gasoline’s, and alternate fuels like gasohol, reformulated gasoline, and all ethanol blends. Max-Boost is safe for oxygen sensors and catalytic converters. Performance engine oils contain higher levels of phosphorus as an anti-wear additive, which can accumulate in catalytic converters and reduce their effectiveness. Max-Boost protects against phosphorus poisoning of catalytic converters.
- Replaces lead additives for protection of non-hardened valve seats
- Raises octane rating up to 30 points or 3 numbers
- Restores power and fuel economy while cleaning deposits from fuel injectors
- Reduces power loss due to knock-retard in computer-controlled vehicles
- Reduces engine knocking/pinging and stabilizes fuel
- Max-Boost is a racing formula and is not street legal.

Okay here is what u need to understand most cheaper octane booster claim to raise 3-8 points thant is on .3-.8 octane. This product raises it 3 full numbers so 91 octane would be 94 octane. What is not clear and i cant find a chart is how many gallons it does that with it says up to 25 gallons but i assume it is very similar to torco and torcos top claimed rating is with 5 gallons. Torco also comes in a 32oz can vs this being 16oz. I am sure it is either 5 orTen gallons of gas and u get 3 full numbers. I mixed a full can with 10 gallons in my 2010 Z1 Turbo snowmobiles with a 4 stage tune. When i go to stage 2 with 91 octane i get a onow light at higer throttle. With this one can mixed with 10 galoons it only came up once all day so that is a huge improvement! Race fuel is way too expensive to but and race fuel is nothing more than normal gasoline with additives just like 93 octane premium is at the pump. I need 91 octane because it has bot ethonal. This product as with torco contains mmt which is a know octan booster. This product is legit but i would not have more than 10 gallons in the tank when u mix it or use 2 cans. Also u add when empty then add gas to mix it up. Torco is still a but better ounce for ounce but this is a very close second and a few buck cheaper. It also fits in my rear bag on my sled so i can add it at gas stops at on the trails.

Well its not cheep. But it really does what I need it to do. I have a 67 built triymp spitfire that can run on 101 but can only get pump gas. It keeps the pre igniton to a min . I use one can for 10 gall. The funnel is worth keeping for other additives

My car is a 2012 Audi S5 with muffler delete and a AWE air intake. This stuff has my car making a lot more pops and bangs on the down shift and in between shifts. It’s definitely improved my gas mileage also.

I live in NorCal and only get up to 91 octane. I have tried several other brands’ octane boosters in my E450 twin turbo 3.0L V6 with only minor improvement. This stuff works! I enjoy driving in Sport+ now as it’s much more responsive and my mileage has improved noticeably. I will be getting a case of this now.

Used this on my C63 for about 7 years, I now use it on my Charger (about 4 months) I’ve never had any issues.
