Every morning when I start my car it sits around 1400rpm... and after 1-2 minutes it settles down at 1100rpm, and that's when i take off.

Is this a good or an unnecesary practice? Do I really need to warm up the car?

(btw i live in dallas so it doesn't even reach below 70* even at midnight)

A good rule of thumb is just wait the 30 seconds, and drive off. I don't start beating on it until she gets to operating temp. Thats the way I've always done it. It all depends. Up here in Wisconsin it gets pretty cold in the winter. In winter, I just let her warm up for about a minute and then go. I was always told its a bad thing to let your car idle excessively. I think it may say in the manual never to let the car idle for periods longer than a minute.

When your idling to warm the car up, you really just want to get a good amount of oil into the engine. In the summer this only takes about 15-30 seconds. In the winter, this could take a minute or two. After that, the best way to warm up is to just keep in under 2500 until the car is up to full operating temp. Idling past those periods does nothing for your car but increase toxin levels in the oil.

Cars aren't like people - they don't need five minutes and a cup of caffine before they can stand not to crash into walls.


With fuel injection being so much more isolated from ambient temperatures than carbs, I don't worry about a warmup cycle. I have a big, human-powered overhead garage door that I shut every morning as I leave for work. By the time I get backed out into the street to accelerate away, the engine has had plenty of time to build some oil pressure.

Getting oil into the works before putting the engine under load seems like the main concern. Like the manual says: no long idling warmup is needed in average weather. (But the manual be damned, in Winter I let it idle as long as it needs to before I can stand to touch the steering wheel.

okay...cool... cause the only reason i let it sit is to let it "settle down"... which is when the tach drops to 1100.

Ah, my car idles at 750rpm once warmed up. I think that's were it should be. 1,100 is a touch high.

Mine idles at 750 too. I give it about 5 seconds in the morning before I go during the summer and maybe 25-30 in the winter. I granny shift it (2,500 rpm) until it's warmed up, though.

Are you kidding me? Insert key, fire it up, crank the stereo, push clutch in, put in reverse, floor it, let clutch out, do a backwards burn out down the driveway, backwards drift into the street, clutch in, 1st gear, clutch out, burn out through first gear, get a mad chirp into second, then granny shift at 2000 to work. Works for me!

Actually, until you're engine is in operating temp. your oil goes through a bypass, thus passing over your oil filter. As long as your oil is clean, you don't have to worry about pumping dirty oil. Just remember, the engineers think "dirty oil is better than no oil". I say filter good oil, that's why I try to let it sit until operating temp. as much as I can. Sometimes letting it sit is too unbearable.

I wait about a good minute or two. With a digital rev meter I know when she is at about 750-850 RPM sh eis ready to go or I just look at my oil pressure gauge and when it drops till about 15-20lbs i'm all set. Oil pressure came up and the car is semi-warm then we dump the clutch and blast the sounds.

I start the car, lock it, head in for round 2 with your mamma, and when she's good and done, the cars warm.

What???? If this were true, our oil pressure light would stay on until the car came up to operating temp. The oil pressure sending unit is attached to the back of the block next to the oil filter. So, no flow to the filter means no flow to the pressure sending unit. Where did you hear this from?
