Oil level

Most accurate oil level is achieved by driving car till it reaches 180 degrees+, driving home at less than 2700 rpm the last half mile, park on a level surface, allow engine to idle for a couple minutes before shutting off. Check oil after an hour.

Thank you sir.

Wow! Leave it to a German company to make it so complicated.

I just check it after it sits overnight, but that probably doesn't answer the OP's question.

If you drive at higher rpms all the way to your "pit stop" more oil is left in the heads before the scavenge pumps can send it back to the sump.

How much oil do you think may be unaccounted for?
Problem here is if it significant, like 1/2 quart, then the dip stick will show low and oil will be added resulting in to much oil in the system.

This seems like it would be good practice when changing oil to get as much in the sump as possible for draining.

I check before I drive after car has been sitting all night. I also try and keep it a bit under the full mark and 1 dash under the full mark on the gauge

I would say 1/4-1/2 qt depending on several factors, oil viscosity,age,temp,rpm's right before shutdown etc.

I recently replaced my clutch, flywheel, & oil. The oil drained/dripped for about 2 months.

Can you imagine the 'labor charges' on the repair bill if every shop waited this long for an oil change..?

All depends on MY...

The newest P-cars require motor to be running at operating temp, on idle and a relatively level surface. Once those conditions are met the measurement occurs over two minutes.

Specific directions per MY will be in each car's manual.

Good luck

Not true.

This true.

SOME definitely DO require: motor be running at operating temp, on idle and a relatively level surface. Once conditions are met the measurement occurs over two minutes. Specifically I know this applies to 2018+ GT3 and honestly it's kinda PITA process...

While others:

Displaying the oil level

Information
Under certain circumstances it is not possible to display the oil level. The reasons for this include:

Engine is cold
Vehicle has been stopped after full-load operation at high engine speeds
Engine oil temperature is too high
A message about this appears on the multifunction display.

Vehicle is level.
The engine is at operating temperature and has been stopped for at least one minute.

And from the 2016 GT4 ... - manual page 82


Bottom line again being, specific directions per model and MY will be in the manual. Personally though, I'm analog and prefer an old fashion dipstick.

Good luck

+1 BB, our 2009 S requires the motor running and up to temp to check the oil. It doesn't have a dip stick to check it manually.

Now I am confused.
I have an 02 Base with a dipstick.
I have been told to check it while hot and while cold.
Which is it?
And am I correct in that it should be at the top of the "bar" on the dipstick?
The electronic level indicator is all over the place with different readings under different conditions (car sitting cold all night, engine warm, after filling up, etc.)
I have yet to figure out what is the proper and most accurate way to check the level.
I tried "Pro drivers" method last night, which was an entirely new way to check the oil level.
Any further input is welcome.
