I start my car up in the morning with the heater on from last night. It takes about 1 minute or maybe 1/2 of a mile more to warm up to each bar. I understand you can turn switch your heater on to relief heat of the motor. Just curious on what your guys take on this.

 

i haven't noticed, but i would expect this to happen. i think how it works is there's a thermostat that will open/close depending on the temp. so if you are using the heater while the car is still warming up it diverts some of the heat and the thermostat will take a little longer to open.

 

Yeah, it only takes me like 3 miles to get to 3 bars on my car. I don't have the heater on or anything though. It just warms up normally like that, of course I do live in Phoenix
