my local auto parts store had some stuff on clearence for $1.00 and I bought a bottle of this stuff. I was thinking about putting some in my P650 to improve cooling system performance.

It says on the bottle. - reduces operating temperature - prevents overheating - lubricates cooling system - For: towing vechiles, trucks, suv's and passenger cars.

Is this stuff similar to the ATV cooling system additive that highlifter and other places sell?

Any info would be appreciated.
