Do you let your Caliber warm up before driving it on a cold morning? How do you determine that the engine is warm enough?
gwilson said:I read somewhere awhile back, I think it was a CAR & Driver article, that about 45 seconds to 1 minute is enough time for a car to warm up. Anything more is just wasting gas, according to the article. I'll see if I can find it.
Edit(a few minutes later):
Did some Google searching, and here is a quote that sums it up nicely...(it's not from Car & Driver but this seems to be the consensus, and this was the answer with the best description)
"In modern vehicles, you do not need excessive warm up time. The minimum that the manufacturers recommend is 30 seconds. Simply enough time to get the oil flowing throughout the engine. If you wanted to wait any longer, you could wait for the car to drop out of fast idle. That is usually an indication that the engine is warm enough for proper operation. Manually increasing the idle above the already fast idle is not recommended."
Same with mine.........doesn't get even near the halfway mark. I only warm up for around a minute or so, just to get the oil flowing. But if I got snow or ice to remove, I will warm it up the whole time untill I'm done cleaning it off.Fingernipp said:
Revving your car up while it's cold makes baby Jesus cry. Don't do it.My45 said:i really hope you guys arent giving you car a long time to warm up, its a waste of gas, and really bad for the environment, all those extra emissions!!! a car only ever needs 30 seconds to warm up and to run properly, especially a brand new car! it might rev higher for a few minutes, but you can drive it. Living in Ontario during this cold spell right now, i can tell you it was -21 C thismorning, and i let me car warm up for a bout 30 seconds before i backed out of my driveway, and it ran fine.
