Understanding the Effects of Winter on Gas Mileage

The Relationship Between Cold Weather and Poor Gas Mileage All internal combustion engines must reach their full operating temperature to operate efficiently. Obviously, it takes longer for an engine to heat up in winter than in summer. From the time you start the engine until it reaches full operating temperature, the fuel system must provide a richer air/fuel mixture to combat the “quenching” effect of cold engine metal. So more fuel is needed to compensate for the “fire” that is quenched, and that’s a major reason why you get lower … Read More
