I get it. You may not wanna hear this. You love that automatic car starter. Stepping (or rather, sitting) your way into an already warm car makes winter that much more bearable. But should you do it? The answer to that is ‘mostly no’. Read on below.
Back when vehicles were made with carburetor engines, they did benefit from being warmed up beforehand. (note: the last carbureted vehicles in the US are from 1990, so if you’re still driving one of those around, kudos to you and keep doing what you’re doing.)
But today’s cars don’t need to be warmed up before driving. Actually, according to Road and Track:
“It takes longer, wastes fuel, and actually increases the wear and tear on your engine.”
So, sorry, but warming up the car beforehand doesn’t really make sense.
So what have we learned?
1 – there’s no value in having your car idle to warm up
2 – ….unless your car is way old and has a carbureted engine
3 – you’re probably still gonna let your car warm up first
