: Engine operating temperature

09-25-2009, 11:32 AM
I noticed my 750i takes about at least 10 minutes to get to normal operating temperature. Seems like about 7-10 miles before it reaches normal temp. Seems really long. Any comments?

What is/are the weather temperature(s) that you've niticed this delay? Does it varies in the morning, afternoon, or evening?

Seems the same whether morning/afternoon or evening. Hmmmm

hmmmm...mine doesn't take that long but i know when i got the car around April and i was using the heater the car warm up faster compare to this time when i'm not using the heater.

When you start the car do you hear the engine rev a little higher and the drop (last a few seconds)?

Yes the car does rev little higher and then drops. I timed how long it took today. It took the engine 15 minutes to get to normal operating temperature. Obviously this is not normal.
Can I ask you or anyone how long it takes for yours to get to normal operating temperature?
Thanks so much

I have had my 750i for only 3 days. It does seem to take awhile to warm up but I noticed the temp gauge is for oil temp not coolant temp. Also my previous 550i didnt even have a temp gauge so I have little basis for comparison. This may be normal.

Oil temps will take longer to reach normal range.
