Messed with my engine. Took a few tankfulls and a couple bottles of fuel system cleaner to get my engine running somewhat right again. Had to change the sparkplugs afterward too. That's how I know deposits built up in the engine. They (sparkplugs) were fouled bad. This Klotz product is a pass for me.

Tried it in my 30 cc RC race boat (2 stroke). Boat actually went 2 mph SLOWER! Ran it 2 oz /gal, and 4 oz /gal.Checked plug and tried different carb settings. Waist of money!!

Update: I tried replicating the effect again but no change, I didn’t feel that increase anymore. I guess this is a pain with EFI cars so to get a consistent advantage you’ll need to tune your ECU for it.Works very well. I drive a 2011 Honda Accord with a K24 / IP Ignition Coils / CAI / removed one catalytic / 2.5" mandrell bent exhaust with Magnaflow and finally, tuned with KTuner. Despite having these light mods making some noticeable difference, the additive makes even more and can feel the extra pull when accelerating.

I use this stuff in all my small engines. Chain saw, snow blower, weed eater. I use it in my 2 cycle atv and boat. This stuff is horse power in a bottle and you can feel it. These hard working small engines defiantly will increase power just like the label says. Helps these small engines start way better too. Makes the Gas more explosive. Read and follow directions. If you put in to much the motor will run on. This happen to me on my weed eater that use to be hard to start. If run on occurs just add gas to dilute. Start with a small amount and work up. Like a chain saw I'd put in one or two cap lid fulls to help start. If you wanted more power maybe 3 or more. Just work your way up a little at a time. In my 90 hp Yamaha boat I run 3 oz. to the gallon.

Definitely woke my Streetglide up with the cam change, compression and porting due to the pour gas that we have here in California. I run around 4.5 to 6.0 oz. per tank. Worth every penny and my programmer compensates as needed for fuel curve. The cooling agent that is blended with it keeps engine temps down also.
