So true. A few months ago my gas mileage started deteriorating but I attributed it to the colder temps. After a while I noticed that my temp gauge had moved slightly (about 1/8 ") to the left of centre so I unlocked my display to check the actual coolant temp, it ranged between 68-70 deg C. Once I changed my thermostat the coolant temp bounced back to 95-97 deg C and my mileage improved by 20%.

I can only guess how much gas I wasted before my temp gauge finally let me know that something was wrong. Now that I know just how much damping is on the gauge (almost 30 deg C) it seems more like an ornament than a source of info. I'll be unlocking my display on a regular basis from now on.
