your car warms up to 4 bars at idle? my car has never even gotten to 4 bars after driving it for 15 hrs straight.....
He has AP2, you have AP1. AP2 clusters have more bars for their temp and fuel gauges than we do.

Those of you sitting there idling the car for long periods of time are doing more harm than good

I've been following SpitfireS' suggestion since I first read it a few weeks back.
Start, sit for ~10 seconds, move.
Of course, shift at a maximum of 3k rpm until engine properly heats up.

A few weeks back?
I posted that on Dec 16, with time difference and all maybe 2 days ago.
Anyway..
About that fuel dillution.
Cold engines run richer on fuel, agreed?
Cold engines burn that rich fuel less efficient, agreed?
Engines at idle stay cold longer, agreed?
Engines NOT at operating temp have (only a little) more clearances between piston rings / cylinder wall, resulting in more fuel rich blow-by, agreed?
Therefore idling you engine to operating temp will result in wasting gas, much more unburned fuel getting past the piston rings and absorbed by the engine oil aka engine oil fuel dilution.

Idling for long period of time results in fuel dilution of your oil. This has been a common trait found on UOAs posted on BITOG.com. Excessive fuel dilution will significantly reduce your oil viscosity.
If you take long trips with your car, this extra gasoline in your oil will gradually be removed through your PCV valve but if your trips are relatively short you will get a significant amount of fuel dilution.

I hold the pedal down to the floor and let it bounce off the 6k RPM rev limiter for the first 60 seconds. Then I do 3 (no more, no less) donuts in my front yard. I then, get out of my car and run around it 3 times, while screaming, "I'M A SISSY LITTLE GIRL!"...then jump back in a drive away.

Either I can tell the future, or I've read what you've written before, 100% positive it was from you.

Got data?
Finally, it's just a big waste of gas. Yeah, I know it's not much money, but you are wasting time, money, and gas just letting it sit there. Shift at 3-4,000 for the first several minutes of driving until everything is at operating temp and you're good to go.
Also, those of you who watch the coolant temp are doing yourselves a disservice if you start thrashing the motor at normal coolant temps. It takes the oil quite a bit longer to warm up and if you're flogging the motor right after the coolant gets up there, you're going to be subjecting your motor to significant oil pressure until it thins out at higher temp.
Though, it's just my opinion, so do whatever you want to YOUR motor.
