Fuel Saving Tips
In the winter, using the heater/defroster immediately after startup may delay the engine's full warm-up to its optimum fuel efficient temperature by a few min. If you have heated seats, turn them on and turn off the heater for the first couple miles or 5 min., so that the engine may warm up faster. Also, don't let the engine run for a few minutes before driving off. Start, buckle up, put on sunglasses and check mirrors, then drive moderately for a few minutes. This tip works especially well on hybrids.
