As the temperature here in Alabama continues to plummet (all the way into the low 90s), I thought today's tip might be of some help. Okay, so the tip is actually for the Winter months, but it's one to file away, because a lot of people (me included many times) make this mistake and use up a lot of gas unnecessarily.
Today's tip is: Avoid Excessive Warming Up of the Engine on Cold Days.
You see those people every morning that the temperature is below 40, turning on their car for 10-15 minutes to "warm it up." Usually what they are doing is letting the defroster clear their windshield instead of doing so by hand.
Back to the engine, though. If you have a regular vehicle (car, truck, van, SUV), the engine only needs about 30 seconds to 1 minute to warm up, unless the temperature is insanely cold.
And, remember, when you are letting that car run for a long time, you are getting exactly 0 miles to the gallon!
