Diesel Ecodriving
Our engines don't have to fight against the vacuum from the throttle plate a gasser has so they are more efficient, but also don't warm up as fast. I have noticed my car gets much better mpg when everything is fully warmed up. My VW diesel has 3 extra glow plugs that heat the coolant when the engine is cold. The coolant heater glow plugs turn off at approximately 180 degrees. I have left them operational for quicker warm-ups but added a plug-in coolant heater to help the engine get to temperature quicker and the glow-plugs to shut off and reduce the load on the alternator. Metrompg did a test of these engine heaters in his car. These could help diesel mileage when the engine has to cold start. I try to resist the urge to run the heater for the first few miles until the engine is warm. Grill blocking helps too.
