Gradual increase in oil consumption
I've noticed a steady increase in oil burning over past couple years. 1200-1300 miles between adding quarts a couple years ago to now 700. What are the most likely suspects? Seems to be more consumption/burning than leaking while idle because at one point recently it was not driven for awhile and I noticed no change in oil level at all. Plus this decrease in oil efficiency has been remarkably steady and gradual.
2006 525XI, 140,000 mi, and I use 5W-30 synthetic. |
How did you check for leaks and if so, where all did you look?

I've never heard of the N52b30 with a burning oil issue

You're going to have to remove a few covers.

Remove under carriage cover and check to see if there's oil on the bottom of the engine. You'll know immediately because oil will be on the covers. Check front of engine from top to bottom. Crank shaft seal is a very known leak spot on the N52

The n52 is definitely burning oil. I have 211,000 miles and every 2-3 k I need to add a half quart. Try adding liqui moly ‘oil saver’ at oil changes. There’s no leaks that bad I’m sure

You’re kidding right?
