    [1].best seller !!, [2].quick arrived, [3].Exactly as described, [4].I would be happy if the accessories were wrapped in cardboard or something to prevent mechanical damage and a fragile warning was affixed to the envelope because heavy cargo is not treated with respect.

    Works great

    Stopped the pinging in my 1969 Cadillac DeVille. I tried many octane boosters but Klotz works the best. I use 1oz for every gallon of gas. Be careful when pouring the product. It’s splashes everywhere.

  • Great product and easy to use

    This product is easy to use. Just pour it into your tank prior to filling up . My car ran smoother and felt like it had more power. I will buy more.

  • Klotz the real Octane Booster!

    It's a great feeling when you can count on a product to do what it claim's. Klotz give's me that confidence especially expensive engines that need high octane fuel. I know when I pour in Klotz I don't have to worry. It's a good feeling and it always performs great when I use it at the track! I just love it.

  • True octane booster.

    I have tried many other so called octane boosters on the market. They usually boost by a very small percentage. Why you are using it in a modified engine it will prove to be very disappointing or disastrous in the results. Klotz is the real deal. I can run up to 10 additional lbs of boost in my turbo engine(performance intercooler and downpipe) and get the results that I want. Do yourself a favor and buy a bottle and try it. You will not be disappointed.

  • Solid product, safely raises octane, NO MMT

    I enjoy using this booster due to the fact that it contains NO MMT, which seems to leave an orange coating on spark plugs and out my exhaust when I use products that contain it. My car runs smoother and stronger and when combined with some e85 for an e30 blend, it's a powerhouse. Besides 100octane from the pump, this is the best way to raise your octane.
