The winters here in Nashua can be brutal. For those of us who like our solitude and a bit of a chill in the air, that’s not necessarily a bad thing. But we can’t help wondering what it does to our Porsche cars. Here’s a bit of counter-intuitive wisdom from your Nashua Porsche dealer: don’t warm up your car this winter.
That doesn’t seem to make sense. After all, doesn’t everyone warm their car up, turn on the heat, and let everything get nice and toasty before they set off for work on those chilly mornings? They do, and if their car was built after 1995, they probably shouldn’t. If you’re driving an older car — and/or an older Porsche model with a carburetor — by all means, warm it up first. But if you’re driving a 2017 Porsche Macan or even a classic Porsche 930 Turbo from 1977, your engine is fuel injected and doesn’t need to be warmed up.
In fact, warming up your car can actually decrease engine life because it promotes engine wear. Here’s why: when your engine is colder, the engine’s ECU pumps a bit more gasoline than usual into the combustion chamber to get the engine temperature up faster. Letting the engine idle with that higher volume of gas actually starts to break down the oil that’s protecting your engine against wear. Do it too often, or for too long, and you’ve got a higher chance of a major repair bill later. The best way to warm the car up is by driving it.
Of course, we’d also urge you to bring your Porsche car or SUV to Porsche of Nashua. Our Nashua Porsche service center is located at 170 Main Dunstable Road in Nashua, NH. We’ll make sure your oil, antifreeze, tires and engine are ready for the cold days ahead, and check for any other hidden issues that could be lurking under the hood.
