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 **Q: How many gallons of gas does this treat?** A: approximately 80 gallons of gas **Q: Can this be used in my jetski. It's a high performance engine and the suggest higher octane which is not available on the river.** A: Yes. You can use it in your jet ski to boost the power/octane. It is still recommended to use the suggested octane level in your jet ski's manual.

For the price, even if you never get to test on a dyno, you will notice a huge difference in throttle response and acceleration once the bottle is fully mixed in the tank and running thought the fuel system. Now this is not for flex fuel vehicles, but does make a huge difference in Turbo powered V6 engines and V8 engines, you will be pleasantly surprised. ### ⭐⭐⭐⭐⭐ 45 MPH punch *by on Reviewed in the United States June 25, 2026* I run a 93 octane tune on my 2017 Camaro SS and a bottle of 104 really perks her up. And bonus MPG which I don’t care about but it tells me my car is burning good fuel. I run this in my 2013 Harley Davidson Breakout as well, same conclusion there. Quality product. I’ve used Lucas, stp, others. I like the 104 the best. ### ⭐⭐⭐⭐⭐ Great for old v8 *by on Reviewed in the United States August 11, 2026* Stops knocking and keeps injectors clean on a well used 30 year old 5.0 l Volvo penta ## Frequently Bought Together - 104+ Performance (10406) Octane Boost - Boosts Octane And Cleans injectors To Improve Engine Performance - Improve Gas Mileage - 1 Bottle Treats Up To 18 Gallons, 16 fl. oz. - STP Octane Booster, Bottled Fuel System Cleaner Restores Lost Power and Acceleration, 5.25 Oz, STP - Lucas Oil 10026 Octane Booster - 15 Ounce --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/6692230-104-performance-10406-octane-boost-boosts-octane-and-cleans-injectors](https://www.desertcart.at/products/6692230-104-performance-10406-octane-boost-boosts-octane-and-cleans-injectors) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-16*
