Review: Excellent product well packaged - Excellent price Product as described well packed and great quality have ordered several times highly recommend to anyone who needs this product Review: This will NOT increase hp, torque, or speed - Do not buy this if you are thinking it will improve your vehicle's performance in some way. I made that mistake of ignorance myself when first grabbing a bottle off the gas station shelf. It likely won't hurt your engine to use one bottle per 15 gallons (they say up to 20), but it's just not what most people think it is/does. **edit*- this DID cause transmission damage, knocks, and pings on my naturally aspirated system. I mistakenly thought that my variable octane (87-93) engine and drive train could handle this change in octane. This was my mistake, I was wrong, and this shouldn't be used on a naturally aspirated engine unless the gas has been sitting for ~6 months and has gone stale. Check with your dealer about your specific vehicle make & model.* Octane boosters raise the octane level of your fuel, making it MORE difficult for gasoline to combust under pressure. They get a bad rap as they're sold as performance enhancers, or speed boosters. High-revving, high psi turbo/supercharged engines can benefit from this as it leads to increased efficiency of combustion. High-octane fuel requiring performance cars that only have access to 87 octane gas stations, or fuel that's been sitting around a few months or more can benefit from this too. You can do some research yourself, but if your vehicle does not specifically recommend using an octane booster or a fuel with octane higher than 91 or 93, then it's likely not for you. Maybe if you only have access to low octane gas, but this is an expensive way to boost it by only a little. You're way better off using 93, or 91 octane as your car will take. Using with regular gas if your car takes regular 87 octane gas will do nothing. I use it in a naturally aspirated 3.8L V6 with 104k miles and it was what was causing me knocks around 3rd gear. Typically a fuel system cleaner (and this part is important!) which SPECIFICALLY lists the detergent levels, not just the name of the chemical the detergent used, is a better bet for increasing performance, but still only by a few hp in the best of scenarios on the oldest of cars in the worst of shape over a long time after a lot of uses, and typically is only around up to 0.5hp. This one doesn't even list the detergent I don't think, just that it has 'jet fuel' whatever tf that actually is. It's not fuel for a jet, that's for sure (kerosine is what jet fuel actually is). There are way way better options for boosting performance, and I'm not sure how this would handle in a system that can't take varying levels of octane. Snake oil for many, but it does have it's uses and works for some very specific cases and again, it does not make sense to me yet why. I have some unknown issue, in a 3-year-old car with a ton of miles for the years, which can take variable octane fuels. I likely have some hairline crack in my fuel system somewhere leaking vapor or letting moisture in. **edit*- it was this octane booster which was contributing to my tranmission knocking issue. After stopping use and going down in fuel grade for a month, it's running like new again.* ## Features - Boosts octane - Reduces knocking and pinging - Helps restore performance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004MBFTYK | | Best Sellers Rank | #6,279 in Automotive ( See Top 100 in Automotive ) #3 in Octane Boosters | | Brand | STP | | Customer Reviews | 4.6 4.6 out of 5 stars (1,366) | | Date First Available | February 4, 2011 | | Exterior | [[Not Applicable]] | | Is Discontinued By Manufacturer | No | | Item Weight | 5.5 ounces | | Item model number | 78574 | | Manufacturer | STP | | Manufacturer Part Number | 78574 | | Model | 78574 | | Position | Outside | | Product Dimensions | 1.5 x 2.3 x 8 inches | | Voltage | 12 Volts | ## Images ![Octane Booster, Bottled Fuel System Cleaner Restores Lost Power and Acceleration, 5.25 Oz, STP - Image 1](https://m.media-amazon.com/images/I/71zd-xxe-qL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How many gallons does it treat?** A: 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. Depending on how often he drives the car and fills the gas tank, he uses 1 bottle with each fill up. I hope this answers some of your question. **Q: does this work on a 2 stroke?** A: Does your 2 stroke recommend a higher octane - 89+ and you can't get the fuel? if so, use it **Q: Is this safe for use with catalytic converters?** A: I am using it in a 66 Mustang and a 73 Z28 neither have converters, so not sure **Q: Will this stuff boost 93 octane to 95?** A: Yes, I think it is a gain of just under 2.5 octane numbers when added to 12 or 14 gallons. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product well packaged *by E***N on April 25, 2026* Excellent price Product as described well packed and great quality have ordered several times highly recommend to anyone who needs this product ### ⭐⭐⭐⭐⭐ This will NOT increase hp, torque, or speed *by S***N on December 26, 2022* Do not buy this if you are thinking it will improve your vehicle's performance in some way.
