In particular I'm looking forward to running this stuff in my diesel truck. Fleet tests have shown an increase in mpg as a result of running higher engine temps using Evan's. Using t-Stats that maintain engine temp around 215 instead of 180 degrees. No worries about boil over at that and higher temps. The down side, for a fleet with multiple drivers is the education and tight control of the maintenance. You don't want drivers topping off with water just because it's readily available.
But Smoky Yunick knew about all this decades ago, the man was ahead of his time when it came to engine temp research and benefits. And look at the manufacturers today, who have steadily increased engine temp heat range to a higher level. They know it too! 190 and higher is common today. If my temps go up, as a result of Evan's coolant, I think that will be a bonus.
1984, Smoky's Fiero get's 51 mpg and does 0-60 mph in 6 seconds (as tested by Hot Rod). There is NO waste heat, that engine is "covered up" in insulating material designed to preserve engine heat. The man, the legend, holds a bunch of patents, he would have been on Evans like white on rice.
