Warm up or drive off?
Hey guys...Just curious if you guys warm up the car before driving, or just get in and go? I remember one of my last car, I babied it, and always let it sit until the needle got to the normal operating temperature, and the RPM dropped.
I just wanted to know what you guys do...BTW It's about 80 degrees here during the day, not sure how much of an effect that has.

I wait until My RPM drop under 1k and my Temperature gauge is up almost half way before I drive the G.
Well the weather helps the engine warm up faster. In the winter my car takes forever just to warm up and get under 1k rpm. I think everyone should warm up there car for at least a min before driving off to let the fluids and stuff run through the engine.

Do you just sit in the car while your waiting?

The book says let the car warm up at least 30 seconds prior to driving. That's what I do. I don't think is necessary to wait until normal operating temp - that's just a waist of gas and excessive idling builds up more carbon deposits. I have historically never kept a car past 3 to 4 years so I have switched my routine from buying into all the hype to just doing what the book says as far as oil changes and other maintenance. It's a lot less expensive that way and quite frankly, changing the oil every 3K to 3.5K is a way to line the pockets of everyone from the oil companies to the oil change shops. Especially if you are putting full synthetic oil in your motor.

That what I do also, even in the winter. 30sec to about 1 min in the winter and take off. But I keep my RPM's low till the engine fully warms up.
That how my father taught me and I have been doing since I got my license and I'm currently 44 years old.

g37brad, I think it really depends on the manner of driving after you start the engine, and the ambient temperature of the engine prior to starting.
Warming up by idling used to be the dogma of older engines. But with good engines nowadays, driving off with the engine rpm in softer range would be OK, and once the temp needle is satisfactory, you could drive at higher rpm ranges. The nice thing about our 3.7 VVEL engine is that it would not take that long to reach optimal working engine temperature. (~3 blocks for me at late spring). Also, the thermostat in most modern engine are quite good to keep the water jacket heated up fast to optimum temperature. The engine coolant fluid also has a high specific heat coefficient and not only could it take in more heat from a hot engine, but it would also keep the heat longer. Also, modern engine coolant fluid has anti-corrosion properties.
When I would most likely do an idling warm-up for ~2-3 minutes is winter season when pre-start engine temperature drops significantly, and usual immediate soft driving in low rpm may not be enough in this particular cases.
Idling an engine longer than necessary would only add to your overall fuel cost & leave more carbon footprints by your car. One advantage when you do have to idle your car by choice like in winter, is that it can be the opportuned time to listen to the engine & note for any weird noices, clanks, hiss or pins. I noted that the cold idle G37 has a brawnier exhaust note when the engine is initially cold, then it changes sound when the engine heats up.
