Is it bad to take off in your car without letting it warm up?

Question

In the morning its about40-50 degrees.

Answer 1

It is actually better NOT to warm your car up before you go. Most 90 and newer cars are made with much lower oil pressure than older vehicles and because of that when you start a vehicle and let it sit at an idle in park the oil pressure never builds high enough to send oil into the top end of the vehicle so it actually causes more wear on the engine and causes taps and knocks from lifters early on in the engines life. So jump on in and run. Hope this helps.

Answer 2

Older car Engines needed a minute to pump up the oil to the valves etc, modern cars do not have the same problem.
It is always best to let an engine warm up before driving off, that is why taxi Engines last longer than other peoples cars because they do not stop/start as much.

Answer 3

"... I turned off my engine at the stoplight, which earned me a curious glance from my passenger and the comment “Don’t you know that turning your engine off at lights causes more pollution and engine damage than just letting it idle?”

Not only did I not know that, I suspected he was wrong. A quick dig proved two things: first, that idling your engine is wasteful; second, that warming up your car is unnecessary, even counterproductive..."

However, I will admit to warming up my car in the mornings of Idaho's winter. Sometimes my windsheild has too much ice on it, that I can't get all off. So I turn on my truck to use the defroster.

Answer 4

Question: How long should I warm my car up before driving?

Answer: In almost all circumstances you should NOT warm up your car before driving. This is the most destructive time for the engine and its related parts The quicker it warms up the better. Your car will warm up much faster driving than just sitting there idling and you will save fuel.

Answer 5

I'm in a climate where it can get to -60 F.
just getting it started can be an art form.
if you worm up the Eng, the transmission is still frozen.
a good hard working engine can do more damage to its frozen tran's.
so, worm up the engine and be nice to your tran's by driving gingerly until it generates its own heat.
have a nice winter !
P.s. your 40. to 50. degrees are nothing to be concerned about, "You" are cold,
but your "Car" likes that temperature range best

Answer 6

It is usual to warm up an engine until the temp guage just starts to move then drive off it means the oil is around the works and doing its job and the engine will last longer.

Answer 7

I always let it warm up at least one minute or tell it ideals down .
I have a 1988 S-10 blazer and it has 403,000 plus miles on it .
I bought it new only major work on it was the transmission at 375,000 mile .

Answer 8

It's better to drive the car it warms up faster,If you have temperatures that low install a block heater.

Answer 9

No because when you start moving it gets up to its proper operating temperature much more quickly. Don't take off like a rabbit but avoid sitting there wastefully idling.

Answer 10

it depends if you have an old car with a carburator you cannot just take off when you want because the choke will shut the car off
