Rislone 4747-12PK Super Concentrated Octane Booster, 6. Fluid_Ounces, 12 Pack , yellow

I decided to purchase for my 2025 Ford Ranger Raptor to determine if I could tell a difference in horse power performance, even though I added a performance calibration computer program along with a Process West enlarged air box, to include the 3.5" cross over pipes to allow the turbos to really breath. My comments of the product are not based on anyrecent Dyno testing. I added one bottle to each of the 5-full tanks of gasoline of Sunoco 94 octane fuel. I did this to give the computer to evaluate and "learn" the fuel mixture change. On the 5th full tank full, I added one bottle and hit the road and accelerator. Truly I was shocked that the product made a noticeable change I could feel from behind the wheel. Both from a full throttle start, highway throtle punch and residential road driving acceleration. Again, not a dyno test but if I can edge out a noticeable difference, that's all I was l99king for. Without any details, I must have surprised drivers in their modified vehicles in the performance of this mid-size pick-up when I pulled away in small level straight and drag racing situations that arose. Additional performance parts will be added in the very near future but at least the gasoline octane booster proved its point to me.

Works, as instructions are, can half the doseage and still works well.

Fast delivery . Thank you! I use this to maintain octane of stored gasoline ⛽️ . Seems to help for a year or more of storage!! Cheap insurance for my fuel investment!!

I only received 11 bottles. Not a big deal cause it’s still cheaper than buying individual bottles

Switched to this booster from Lucas. This is WAY better. My GMC Sierra (6.2L) loved it...huge bump in power. I even put it in my Mazda CX50 Turbo - same deal. More power, engine revs nicely. I run 91 octane (no ethanol) pump gas in both vehicles. I pour in one bottle Rislone after fueling up on a full tank. So, it works on turbo engines and non turbo engines

Helps big time

This is a very good octane booster but I'm very disappointed because you cannot buy just a six pack anymore where they did on purpose so I'd have to start buying 12 packs but it is a really wonderful product that won't will not ruin your cat a lot of converter turbo or any plastic parts in your vehicle wonderful octane booster just I wish you would make smaller packages please

Works well on NA and turbo charged vehicles, and increased response on the throttle. Just pour into an empty tank (or near empty)and fill up to get the best results and repeat!... Cleaner emissions over continued use!

I use this religiously in all my harleys to offset lower quality pump gas. Bottle size is perfect fit for my swingarm bag. Usually get 3 to 4 fill ups from a single bottle. Won't ride without it.
