Thermal efficiency improves as the temp goes up also so you get better mileage and power. Want the incoming air really cold and the engine hot! -----Original Message----- From: Forward Look Mopar Discussion List [mailto:L-FORWARDLOOK@xxxxxxxxxxxxx] On Behalf Of Tom Stroup Sent: Wednesday, January 07, 2004 11:42 PM To: L-FORWARDLOOK@xxxxxxxxxxxxx Subject: Re: [FWDLK] Dumb question Actually, it is a great question. You want to run a thermostat that will allow your vehicle to get warm enough to evaporate the moisture and gasoline from the crankcase. These get in there from ambient air and from fumes that get past the rings from products of combustion. If you don't drive far enough, or get the vehicle warm enough, they won't evaporate and/ or be eliminated through PCV or a road draft tube, or whatever your car has. If remaining in the engine, they can lead to rust and corrosion and bearing pitting, etc. Usually, you want around 180 degree thermostat. It takes about a twenty mile drive with that to get the oil up to temp. As you increase the temp, the oil will more quickly oxidize and you must change it more often. Newer cars run 195 or so to have thin oil to pump and have closer parts tolerances to fit closer. Thinner oil is easier to pump, leaving less power consumed, and a hair better fuel economy. The manufacturers are after any increase in fuel mileage. They don't care if your car's hoses and wiring get baked under there.

Thermostats come it various degrees for our cars (i.e. 160,180,190, etc.). What would be the reason for running what degree? Engine temp.? Outside temp.? Heater temp?
