When the temp is in the 30s the low coolant temp light will turn off in 1.5-2 miles if I forget to plug the block heaater in. with the heater plugged in it goes off within a block and a half. Which makes a difference in the first to 5 minute bars on the consumption screen. Instead of under 25 then just over 25 with the heater it is over 25 then almost 50.
