It works great, for track or daily driver.
Great product. I run two bottles of this Hyper Coolant Super Coolant and all water in my 78 GMC Caballero drag car. Keeps coolant temperatures down between runs. Also provides excellent corrosion protection so you can run all water without any antifreeze or coolant for track purposes. I also run this stuff in both of my Ram trucks and my C5 Vette. Works just as well as Water Wetter but much cheaper.

It works, keeps engines cooler.
My 1972 Oldsmobile 442 Convertible runs hot with the original 4 core radiator and belt driven fan. This keeps it from overheating. I also use this in my modern BMW cars for both the engine cooling and the air charge cooler for the turbos. Especially in my 750 with twin turbo "hot V" where the turbos are in the V of the block and get really hot.

I use one in my motorcycle
I like to use it for a little extra safety for lowering coolant temp, great for motorcycles

A radiator coolant additive that reduces engine temps and corrosion protection!
I use this super coolant additive for both of my vehicles and it works as expected. I would use it again. Check with your manufacturer first to see if its compatible with your vehicles.

Nice Additive
Love this stuff works great helps a little especially when it's very hot out. Make sure you put good antifreeze in your car and add a bottle of this, also change your thermostat to a lower temperature in the extreme summer heat. If you like add a couple extra radiator fans in front of your condenser with a separate toggle switch I added two 8-in fans and my temperature in the extreme heat stays between 180 and 195. It used to go up to over 220.

Didn't notice much difference
My 87 VW Westphalia has been running a bit warmer than I like, even though it's a new radiator. Figured this might help, but really haven't noticed a difference.
