Evans is great coolant for classic cars that aren't run very much IF the car has a radiator larger than it really needs. Lots of cars do have a larger radiator to cope with degradation over time. I ran Evans in my Mini Cooper (original) because the car is notorious for overheating. Evans made a bad situation worse. Not only did the temp sensor say the car was running hotter, but you could simply put your hand on any part of the block and it was quite a bit hotter, like 30 degrees. So much for Evans claims that metal temps will be lower! On the other hand, if your car can run at the thermostat temp all day long with Evans coolant in then you are a winner because the Evans has zero rust and corrosion issues. I don't think that Evans coolant is the answer for cars and bikes that tend to overheat with normal coolant, it just makes the problem worse.
