About this item:
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.

5.0 out of 5 stars Boost
This product provided a noticeable improvement in low end torque in a turbocharged 4 cylinder. I did not notice a significant difference on the top of the rev range. It was worth using when it is very hot and humid in Florida.
5.0 out of 5 stars The Very Best in Octane Boosters
I have used Royal Purple products for many years, the formulation of all their products, from break-in oil to heavy duty gear lube has helped all the vehicles I keep up the maintenance on perform top notch, last longer, save my family a good bit of $$$$$$- I started using their "Max-Boost Octane Booster" when I had a brand new GMC 7.4 Lt. (454 ci.) crate engine installed in my 1994 K-2500, after using the break-in oil 3 changes in 5,000 miles, I had ordered 9.5 to 1 compression pistons for my new engine and knew I would need high octane fuel to allow the beast to run at it's best. With a 4:10 gear ratio I was not expecting more than 10-12 mpg.- after 21,000 miles (using R.P. fuel system treatment & Max-Boost) I get 14-15.5 on the Hwy. (if I keep it under 70 Mph) With a manual 5 speed (NV4500) even at 75-80 Mph. I get 12.5-13 Mpg. I'm a bit excessive when it comes to my truck, as I'm disabled and 84 miles from the Dr. office and 75 miles from the nearest Wal-Mart- N.E. Wyoming winters can be brutal, summer can see temps. near 100- long story short, from -40 to +100 this octane booster is the very best (I use no ethanol fuel) 91 octane fuel and R.P. keeps my outfit purring like a tiger- Thanks Bolo and much thanks Royal Purple for all the fluids in my GMC and my 77 yr. young mother's 2005 Toyota Tundra

5.0 out of 5 stars The real deal but need 2 cans for a full tank of gas (15-20 galons)
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.
5.0 out of 5 stars This stuff works
I use pure non-ethanol in my vintage motorcycles that are resto-mods. I put royal purple in the fuel and what a combination for performance. I also put royal purple in my Honda Pilot SUV when I go on a trip. Noticeable difference in all areas.
5.0 out of 5 stars Made my M4 GTS more powerful
Great stuff! I used this with my 2016 M4 GTS and it is flawless. I put this in when my gas was running low and then I filled up my tank so everything can mix in. To be honest I was skeptical at first but it did give me a noticeable performance boost. A bit of background, I was staying in California during the time of testing and the only available gas there is 91 octane instead of the recommended 93 needed for my car. Yes it is not that big of a difference you may think, but my tests show otherwise. I will dyno the car later on to prove my word. The car sounds much more aggressive and burbles more, the engine just sounds much happier when this in the tank. I also tried it with my 2013 Honda Accord in which it didn’t have a noticeable difference. As for MPG, it does not make any difference whatsoever, at least for my cars. I’d highly recommend this for cars which have higher compression ratios that can benefit from high octane. 10/10 in my book, I use this every fill up, got one in my trunk at all times.
