Hello everyone. I have an '02 and was wondering if it is neccesary to warm up engine before pulling off? I developed this habit due to my previous jeep being a '91 and I also had a '86 chevy silverado. Just wondering what you guys do.

I usually go out and start my vehicles then let them run while I go take out the trash or pick up the trash cans ect. But one thing I never do is start a vehicle and shut it off without letting it warm up. Funny thing is my Ram van and wifes Pilot can sit and idle for minutes without the temp. gauges moving. My 2011 Jk temp. gauge moves after a few seconds.

My dealer told me to warm it up for a few minutes b4 driving. I dont think its necessary, but do it anyway. I guess I feel today's engines are better designed and made and think the "warm-up" is a dying practice. My reason for this thought is from my previous cars '05 X5 and '08 G8 where the manuels state theres no need to warm up the car.

I follow the rule BMW gives you, since I have never seen anything else in a car manual before. They say to not let it warm up, but to start driving mildly after only a few moments. This prevents carbon buildup. You can drive normally after it reaches OT on the road.

Works for me, but sometimes the cab is cold as hell. :).

The concept of warming a car up, is primarily due to the carberators of yesteryear. A 'cold' car simply wouldn't run right until the air around the carb was of sufficient temp so the air/fuel mixture was right.

In today's fuel injection, the computer controls all of that, so it's much easier to run 'em cold.

Yes, there are some issues with wear and tear, but in my lowly opinion, you have more wear during startup due to lack of oil (until the oil pump starts) than due to heat expansion rates of dis-similar metals.

So simple common sense comes into play. Drive the car like you want it to last. Gentle is always better than abusive. Easy is always better than hard.

Now once they're up to operating temps, then have fun.
