I posted a thread recently about how bad my fuel economy has become and I have a theory about it. Correct me if I am wrong, but the cooler a car runs it also will run much richer, using more gas. With the lower temp thermostat and my adjustable thermostat, the temp needle rarely gets past the C in the gauge.
Also being winter, I am using my heater almost all the time. Doesn't the heater run the fan when it is on too?
My main question is where is a good position on the gauge for the needle to rest at? Or better yet, at what point on the gauge does the temperature become dangerous or overheat?
On a side note, can the color of the motor oil determine if the car is running rich? I told my friend that my oil gets black soon after changing it and he said that it is an indication of a rich condition. On my Mustang, the oil stays nice and clean up until I change it. Thanks for any input.
