It works, works really GOOD
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

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

This is a really good product
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

If you have a GDI vehicle, get this!
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!

Really works
This actually works, Toyota 86 recomends a 93 octane and living in California you only have a 91 octane

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.
