Winter Weather Warmup

[Ghostbear]

:w00t:

A small question as temperatures drop. What rpm's do you use when your car is cold and at which oil temp do you start wo work the car?

I try to keep the car below 3k rpms until i hit 70° celsius, after that max 4k rpm till 110° Celsius after which most of the time i switch gears at 5-6k. (If I want to go fast) Most of the time my car is around 2.5-3.5 k rpm.

I think you have it correct. I have been told this is in the manual. Just FYI you...*smile* Any other takers?

PS
I just noticed you call your car the "batmobile"

you might be one person who should look at the mod where the hood has vents. Then it will really look like a batmobile! (maybe you already have them?)

If I could, my1 would fly like Hans Solo

While the manual says not to idle the engine to warm it up (p.98), I can't find any other warm-up instructions.

Since my 128i has no temp gauge, I asked my dealer about warm-up & was told that BMW suggests driving it moderately for a minute or two - and after that anything goes as the engine will then be sufficiently warmed up. Somehow, I don't feel that redlining mine after only two minutes of running time is a particularly good idea!

Tom K.,

I totally agree.

Is that all it says? Hmmm anyway, I was just going on what others have said here. I don't even know where my manual is? (kidding, it's in the east wing, 8th floor, bmw room, 34th isle, second file, next to the pizza I ate last time I put it there.)

Good thing I have a pdf floating around on my iPhone.

I have not really even redlined mine yet.

PS thanks for looking it up. It will make a good search the next time this comes up.

i thought there was something about turbocharged cars where its best to just drive the car at low RPMs after a cold start rather than letting it idle.

That's true for any car.

BMW has stated in the manual even in my 2004 E46 318ci that when you start up the car drive slow until it warms up and don't let it warm up while sitting at idle

I also read here somewhere that after a hard drive, one should not just turn it off, but do a "cool down drive" or let it sit a bit? True?

Not an issue really anymore. The fan will run to cool off the engine and synthetic oil won't ... I'm not sure what the word is ... it won't turn all nasty and gunk up your engine like used to happen in the past. Turbo timers are pretty much unnecessary these days. But after a hard drive (like at the track), yes, you should definitely let it cool down. I always do it after a long trip too, just to be safe.

it's called coking.

the rad fan will cool the motor and we have an oil cooler, but yeah, best bet isn't to push oil through two highly boosting turbos (floored) and just shut the car off... to allow it to run through the system without boost is substantially cooler than even boosting a little bit.

I would always ensure that the last < mile of my trip is done without any boost at all... i mean who pulls into their driveway / garage at 5psi

I always drive easy for the first 10 minutes of a trip and the last 5... just extra measure and easy to do.
