After reading the recent thread about cool running. It started to make me wonder!! It takes me between about 8 and 15mins to drive to work on mainly 40mph roads with a short bit of dual track about 2 miles at 80mph. When I am approaching work my temp is approx 70 ish and rising slowly. Its obviously going to take longer now as it is only 6 degrees in the morning and lots of cold air will mean the car will take longer to warm up. Also with the heaters on this will also take heat out of engine. How long do other peoples cars take to get to 90?????????????? Do you think I need to visit the thermostat fairy??
