What is considered normal oil consumption on the GL450? Any service bulletins regarding this matter?

I have over 80,000 miles on my GL450 and it does not require any oil between oil changes. My change intervals are greater than 10,000 miles.

More than a quart between changes should be too much.

If yours is brand new, you should wait a while.

What kind of oil are you using?

Have you owned it since new?

High oil consumption would indicate en engine overheat or coked compression rings from the use of conventional oil.

Also if you are using a 5w30 or worse a 0w30 these are not an approved viscosity for your engine in North America ( temperature issues).
