SHOULD I LET MY CAR IDLE?
The cold Illinois winters are almost here. Get your shovels ready, your car brushes, install those snow tires, and purchase the bags of salt! Mother Nature seems to always send us one big snow storm every year. When it happens, you’ll head outside and clean off your GM and potentially let it run idle to “warm up” for an extended period of time, thinking this will prevent the engine from seizing. Contrarily to this belief, you do not need to let your car run idle in the cold.
“Unless you are trying to defrost the windshield or warm the interior of your car, idling is not required for today’s vehicles,” said Rich White, executive director of Car Care Council. “In most cases, idling longer than 30 seconds is unnecessary. The best way to warm up your car’s engine is to drive gently at the start. Remember, a vehicle gets zero miles per gallon when idling and the result is lower fuel economy and wasted money.”
When the car is moving, that is when the engine oil moves more efficiently and lubricates the moving parts better. In fact, just letting the car run idly will only remove oil from the engine’s cylinders and pistons which is contradictory to your intentions in the first place.
What Started This Practice?
This practice started decades ago when cars were built with carburetors. Vehicles today are not typically made with these systems anymore. This especially rings true for Buicks and GMCs because these modern vehicles are built with new fuel-injection technology, complex computer systems, and thinner synthetic oils which allows drivers to skip the warming up process before going on the road.
What You Should Do When It Snows
When the snow starts to calm down, head out there and shovel your car out. Do not wait before nightfall to do so because the snow will start to harden over your GM model. If you want assistance in cleaning your car off, you can turn it on. But, you just want to make sure you flip on the rear windshield defroster and direct the heat towards the front windshield. This will make clearing the snow off your car an easier process. Once your car is completely cleared of snow and ice, turn off your GMC, since there is no need to have it run for an extended period of time.
Once you hop onto the road after a huge snowstorm, the first 15 minutes is where your Buick or GMC gets warmed up. While you’re on the road, remember to take it easy in the beginning to prevent any pressure being put on the engine. Moreover, the roads will be slippery, so drive carefully. Take your time driving around and you will keep your vehicle in fantastic health this winter season!
