Thermostat: 180 or 195?
My Metro's G10 seems to be lacking a thermostat as it will not heat up, so I went out and bought one. I got a 195 degree model on the theory that the engine would run more efficiently at a higher temperature. However, this does have me wondering if I am correct? Would the 180 have been the better choice? I'm curious if anyone has ever done A-B-A testing on this before and if it makes any real difference at all.
