Question:	How many gallons does it treat
Answer:	The front of the container states "Treats up to 21 gallons" -- my husband uses this product in our 1965 Mustang, which has a tank size of 16 gallons.

Product description

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.

User questions & answers

Question:	How well does this clean Oil Control rings? Im trying to try everything without taking engine apart
Answer:	It's an octane booster, not a cleaner, you probably need a different product
Question:	Can you use this with 2 stroke engines
Answer:	I would stay away from it. It will foul your plugs pretty quickly and it doesn't really have any added benefit if you ask me.
Question:	Item title says 6pack? Or just misleading
Answer:	Not a six-pack
Question:	am I going to go to jail for using this product? it says street illegal
Answer:	The real answer is yes, you get a fine and you might loose your car… if and only if you add it to your car's tank and while driving it you encounter a police road block, similar to alcohol checking, taking samples of the gas in your tank. LOL, ok science fiction. Reality says that if you are street racing and crash into an innocent driver… if they could find this additive in your gas tank it would add up to another fine, which of course is nonsensical at that given point too lol Yeah, it's marketing… I just had to do the mental process, it was fun lol

Product description

Rislone Super Concentrated Octane Booster increases your fuel's octane rating to stop engine hesitation, knock and ping, while also increasing power and performance. The formula works equally well on classic muscle cars, newer, smaller, harder-working engines, off-road and racing applications. The increased octane allows the engine to run optimum spark timing, which not only creates more power, but also, in many engines, reduces emissions and increases fuel mileage. It's also the best insurance against bad gas you can find.

• Nozzle allows it to be poured into all fuel tanks, including cap less systems
• Maintains optimum engine efficiency and power
• Use with gasoline and ethanol E10 and E15
• 1 bottle treats up to 20 gallons of gasoline
• Will not harm catalytic converters or oxygen sensors

Frequently Asked Questions

Antiknock formulation stops engine knocks and pings caused by low quality fuel.

What is spark knock?

Spark knock, also known as knock, detonation, knocking or pinging in gasoline engines is when the air/fuel mixture in the cylinder explodes separately from the main ignition caused by the spark plug. This usually creates a metallic “knock” sound as the two fronts collide with each other causing extreme pressure inside the cylinder and possible engine damage.

Can I use with any type of gasoline?

Yes, Rislone Octane Booster works with unleaded gasoline, ethanol E10 E15 E85 flex fuels and racing fuel.

User questions & answers

Question:	How many gallons does this bottle treat for 87 to 92 octane
Answer:	It has a blending chart on the back of the can, which makes it really easy to reach the octane you desire..... 87 to 92 = 2.5 oz per gallon, fyi the chart only shows 87 to 91 or 93 so that's just a bit of a eyeball questimate.
Question:	Does it contains MMT
Answer:	Yes it does contain the highest quality methylcyclopentadienyl manganese tricarbonyl (MMT). It is a very effective octane booster that doesn't damage oxygen sensors or catalytic converters so it is ideal for modern cars
Question:	What is the mixture ratio
Answer:	Mixture ratio can be found at racegas.com.
Question:	will raise pump gas by 40 points or 4 full numbers, up to 105 octane",so how much of this to raise 18 gallons to 100 octane? Doesn't give ratio here
Answer:	What is the octane of the 18 gallons you have already? 2 oz of the concentrate will boost it 4 points per gallon. For example, If you have 16 gallons of 93. Adding a whole can (32oz) would bring you to roughly 97 octane. Two full cans would bring you to 101. So on 18 gallons of 93 octane, you would need just over 2 cans to bring you to 100 octane.

• Boosts power!
• Get better gas mileage
• Cleans fuel injectors
• Reduces knocks, pings and hesitation
• Safe for catalytic converters & oxygen sensors

User questions & answers

Question:	I have a 2014 harley ultra limited. is this product safe on v-twin motors
Answer:	Yes. But it doesn't boost your octane anywhere to 104. I buy extremely high octane fuel at an airport nearby, and blend it with fuel from the gas pump. I'm really getting that CLEAN burn this way. A 5 gallon can of 107 0ctane fuel, blended with 92 octane from the pump works for me, and for a while.
Question:	How many gallons of gas does this treat
Answer:	approximately 80 gallons of gas
Question:	I have 2019 bmw 430i with an ecu tune installed, would half a bottle for 14 gallon tank be enough to go from 91 to 93+ octane? the tune recommends
Answer:	So formula is: ((% fuel A X octane of A) + (% fuel B X octane of B)) = Octane of mix. So your case : 14/17=82%, 3/17=18%. Therefore, ((.82X91) + (.18 X110) = 95 Octane I have a 17 gallon tank and I brought 110 octane and got 91 octane from the gas station So 14 gallons of 91 octane , 3 gallons of 110 brought me up to 95 octane. You can plug your numbers in the formula. Hope this helps
Question:	my car is having pinging noise, but it takes 87 octane for gas. can i use this to get rid of the noise
Answer:	Yes but purchasing a higher octane gas would be a better idea.

User questions & answers

Question:	Can this be used on a mini van
Answer:	Sure, It can be used in any gasoline engine that's needs a boost in octane.
Question:	can i mix this with fuel injector
Answer:	Yes. Just don’t mix this stuff with high contents of ethanol fuel. They don’t mix well. That’s about all I know not to mix with lucas
Question:	adding 4 bottles to a 22gal tank will it make you have around a 91+ octan ? needing to know adding tuner to my truck. it has 87 oct now
Answer:	So the truck has 87 octane in it, and you're wanting to know if adding 4 bottles will bring it up to at least 91 octane? (22 gallons) 1 bottle per 10 gallons will increase your octane rating by about 3.6, so yes.
Question:	Can I put this in my lawn mover
Answer:	Are you planning on racing your lawn mower ? If not, flush your fuel system, new filter, make sure your carb and lines are gum free (from the crap ethanol), new spark plug. Fill your tank with (cheap) 89 octane fuel and your mower should run like new. No need for 91+ octane (unless you're racing. If so, please post video).

User questions & answers

Question:	How long can I keep them unused
Answer:	i use one can everytime i fill up; i use only SUNOCO 93 octane gas and add this; it's going in a 2015 Porsche 911-4S; the fuel additive is fresh; sealed and does not get stale. All I can say is i notice no drop off in performance from can number one to can number six; possibly a petroleum chemist could better answer this inquiry, but as for my 911, it runs perfect with or without the additive; i am certain if you add the entire can per fill up, 10 gallons or more, there is not a problem.

• Will not harm sensors or catalytic converters
• Contains MMT
• Increases octane level and restores lost horsepower
• Shelf life 5 years

User questions & answers

Question:	What is the ratio of product to fuel and what level of MMT is obtained at that concentration
Answer:	1 bottle will treat a tank of 20 gallons. I'm not sure what the level of mmt would be. I have to use this in addition to a lead substitute for my 1966 Fleetwood, when those cars were produced in that era gas was 95 octane, so this helps the car runs beautifully. It is also totally safe for fuel-injected engines as I put them in my other cars all the time. I've tried many others that cost upwards of $10 or more per bottle and those are junk, for the money this brand is the absolute best. Hope this helps!
Question:	will this product increase 87 octane

Question:	Can you use on carbureted engines

User questions & answers

Question:	How many gallons of gas does "lucas luc10026 multicolor 15 ounce octane boost" treat
Answer:	13 to 25 gallons. Naturally if you add it to 16 gallon tank your octane will be higher than if you add it to a 25 gallon tank. The key is to add it to an empty tank right before you fill up. And it will work well.
Question:	What is a typical ratio that everyone uses that works
Answer:	Hi Anthony, I use the whole bottle of Lucas Octane Booster with my 20 gallon tank and 93 octane Sunoco for my modified 440 six pack Challenger works great but depending on your engine combination you may get away with using less octane booster I buy Lucas by the case from Amazon (best price) Lucas told me to store this product in a dark place !
Question:	oz to 25 gallons what is the ratio for my 3 gallon tank 5 oz to my 3 gallons
Answer:	Directions say 15 ounces will treat up to 25 gallons, that ratio equals .6 ounce per gallon. You would be fine with 1 ounce per gallon.
Question:	how many gallons of fuel will one bottle treat
Answer:	3 ounces of Lucas Octane Booster treats 5 gallons and will raise octane by 30 points. This means if you add 3 ounces to 5 gallons of 91 octane, you'll have 5 gallons and 3 ounces of 94 octane fuel. Since this bottle is 15 ounces of additive it will treat 25 gallons of fuel if you dump the whole thing in.
