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

This really works. I absolutely love this stuff, because I get an extra 2 to 3 mpg per tank using it.Unfortunately, as the price continues creeping up and up, the sellers, or the manufacturer, or someone out there needs to realize it's becoming more and more likely that I'm going to reach for the "Super" pump. When the cost starts to negate the benefit, I'll stop using this, and start using the 93 pump instead.Luckily, the last I ordered, it was still under $40 for a 12 pack. That was less than 2 months ago. Now it's almost $50. I can't recommend it as highly as I once did because of the price increase.

Use this in my tuned vehicle. Way cheaper than runner 93 octane here. Was getting some spark know on 87, but add a bottle of this to every other tank full and no spark know.

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!!
