13 best nos octane boosters

Nos Octane Boosters are a type of fuel additive used in the automotive industry to increase the octane rating of gasoline. Octane is a measure of a fuel's resistance to "knocking" or "pinging" during combustion, which can lead to engine damage and reduced performance. Higher octane fuels are typically required or recommended for high-performance engines or those with high compression ratios.

Here are some key points about Nos Octane Boosters:

  1. Octane Rating: The octane rating of a fuel indicates its ability to resist detonation or knocking. Higher-octane fuels have a greater resistance to knocking, which is important for high-performance engines.

  2. Performance Enhancement: Nos Octane Boosters are designed to improve engine performance by increasing the octane rating of the gasoline. This can lead to smoother and more efficient combustion, potentially increasing horsepower and torque.

  3. Detonation Prevention: High-performance and turbocharged engines are more prone to detonation, which can cause engine damage. Using an octane booster can help prevent detonation in such engines.

  4. Fuel Stabilization: Some octane boosters also contain additives that can help stabilize fuel during storage, preventing it from degrading over time.

  5. Compatibility: It's essential to choose an octane booster that is compatible with your vehicle's engine and fuel system.Always follow the manufacturer's recommendations and guidelines for the specific product you are using.

  6. Instructions: Octane boosters typically come with instructions on how to use them. It's crucial to follow these instructions carefully to achieve the desired results and avoid over-treating the fuel, which can be detrimental.

  7. Cost: Octane boosters are available in various price ranges, depending on their brand and features. Some are designed for regular use, while others are formulated for occasional or specific performance needs.

  8. Alternative Solutions: While octane boosters can be beneficial for certain situations, it's essential to consider other factors affecting engine performance, such as proper maintenance, using the correct fuel grade, and tuning your vehicle's engine for optimal performance.

In summary, Nos Octane Boosters are fuel additives used to increase the octane rating of gasoline, primarily for improving engine performance and preventing knocking in high-performance or turbocharged engines. However, they should be used in accordance with the manufacturer's recommendations and not as a replacement for proper engine maintenance and tuning.

User questions & answers

Question: I put this in my chevy cobalt and i think it made it slower. It sounds different too. How can i fix this? Please help
Answer: One 80oz bottle treats up to 250 gallons
Question: Toyota Highlander, will this product give more acceleration even though I use premium 91 Octane gas
Answer: I was told to pour it in before my winter deliveries. My outdoor tank is 275, but capacity is listed as 266. I'd say I add about 16 oz and maybe more if freezing temps are in the forecast.
Question: Is this safe to use in 2007 Rav4 V
Answer: According to the labeling on the 16oz bottle, 16oz treats up to 40 gallons. Thus this 80oz bottle should treat up to 200 gallons since there are five 16oz bottles in a 80oz container (5 x 40gal = 200gal).
Question: Is this safe for a 3.8 2002 mustang
Answer: Because Diesal 911 ( hence the emergency reference ) means that you already have a problem. It will get you out of a situation in which the fuel has already gelled. I personally use Howe's Diesal Treatment in my vehicles, and always have a bottle of 911 behind the seat just in case

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

User questions & answers

Question: Does this burn sooty ? Has anyone checked their plugs after using this
Answer: I run this in a 2007 Shelby mustang. Burns clean and does not cause any check engine lights to come on, put some in my lawn mower because in was sputtering and the plug went from black to a nice tan color. Does give 93 octane a little extra kick. I am on about the 5th gallon in the car and add it to cheap gas for the mower.if you are going to get it order something to measure the correct amount
Question: Up to 10 numbers means 87 octane will become 97 or near that
Answer: If I remember correctly, it said that it raises the octane 2.5 points per ounce/per gallon. If you wanted to raise the octane 10 points, you'd have to use 4 ounces per gallon. That gets pretty expensive. You might be better off just buying 91 or 93 octane and boosting it from there. I need 93 octane for my Stage 3 Turbo RZR. I add 1 oz. per gallon. That puts me at 93.5 octane. I throw sand 30' behind me climbing steep sand mountains. Does the job easy. Hats off to Klotz!
Question: Can this be used in a 2013 ford taurus 3.5 l v6 n/a that takes 87 fuel
Answer: Absolutely, you will probably notice a fuel mileage increase.
Question: How much of this product do you use per gallon of fuel
Answer: Every oz of Klutz Octane Booster per gallon of gas, raises the octane by 2-1/2 points. So, if you are looking to increase your octane by 2-1/2 and your car holds 25 gallons, then you would have to use 25 oz of Klutz. If you were looking to increase your octane by 1 point and your car holds 25 gallons of gas, then you would only have to use 10 oz of Klutz.

User questions & answers

Question: is this a case of 6, 16 oz. bottles
Answer: yes, 6 - 16 oz bottles
Question: how many oz are recommended to mixed per gallons of gasoline
Answer: Treats "up to" 25 gallons per 16 oz can. So 0.64 oz per gallon. I use half a can with a 12 gal fuel tank. Gives you about a 3 boost on the octane number when used this way.
Question: I have 90 in my area will I need a full bottle to make 93 or half with 18gallon tank
Answer: one bottle treat will 18 gallons or if you want to be precise one ounce per gallon of unleaded fuel. I use this in my Shelby SC Cobra 427. If you are just trying to bump up the rating I would find 93 fuel as it can get expensive to use at each fill up. I run only 93 NON ethanol gas and use it at each tank refill but then my car is primarily a show car. Hope this helps.

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: Why does the title say sce gaskets 135076 gasket
Answer: Maybe you put too much, considering the small fuel tank. Plus spark plugs have been known to foul with any octane boost. I would suggest giving the car a tune up, then run the tank to almost empty, then fill up with premium with no octane boost. Also I use only a "top tier" premium gas such as shell, mobil, valero, exxon, look on the web for top tier gas brands. Their better fuels than non top tier fuels. Keep away from speedway gas, its cheap and will burn too quickly. You'll get better mpg on premium and it will keep your plugs and valves cleaner longer. I only use premium in my 460 hp mustang gt and my wifes 4 cyl subaru. Try it, you"ll see, good luck!
Question: Can i add this to my 2006 honda cbr600 f4i
Answer: No. As far as that goes, neither will running higher octane fuel than what the manufacturer mandates. Increasing octane helps reduce knock/pinging. Higher octane simply makes the fuel more resistance to knock. It doesn't make your car faster, more powerful, efficient, safer, better looking, etc. With all this said, on a hot day under a load (think pulling a trailer up a hill in high temperatures) your vehicle (most anything built 1990s+) will detect knock/pinging and compensate for this by reducing the power output to prevent more serious engine damage. In these events, and or if you hear knocking/pinging from under the hood, utilizing a higher octane and or a supplement that in fact does increase you octane can help with this. If you're not experiencing such symptoms, you're essentially wasting your money.
Question: is this a lead additive
Answer: Hi,If the compression ratio of your engine is less than 11.5:1, you do not need it and it will actively degrade the performance of the engine by promoting deposits formation. this product actually makes the fuel less prone to detonate prematurely buy making it less prone to detonate. If the compression ration is low the engine will not manage to burn the fuel efficiently when this product is used, effectively reducing its power output and formation of deposits. for a high performance engine with a high compression ratio its a completely different story. the engine runs smoother, it heats less, and burns the fuel more efficiently and cleaner.
Question: Is this six of these royal purple roy
Answer: Yeah should be if you are putting regular 87-94 octane pump gas in it

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: 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.

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!
