    Big difference in engine cooling efficiency

    Engine Ice doesn't make your engine run "colder," so not sure of those claims. Engines are made to operate in an optimal temperature range, so what this does is allows your engine to dissipate heat a WHOLE lot better. In other words, whereas stock coolant may boil over when riding slower trails where the engine is working really hard (rock climbing, etc.), Engine Ice handles it more efficiently and dissipates the heat better. Under those loads, the reduction in temperature is really a prevention of the INCREASE in temperature by up to 50-degrees. I can tell the difference already. The radiator fan doesn't come on nearly as often, and my temperature gauge rarely, if ever goes above 2 clicks now (used to hit 3 on an average ride). I think the engine is benefiting from this better coolant. And for the price, you really can't beat this upgrade in cooling efficiency. :)

    Good coolant

    Used to replace coolant that was in a bike I recently bought. I was having a problem boiling over every ride, since I changed my coolant I have not boiled over once.
