Engine oil OEM BMW or FUCHS

Using it for 5 years, changing oil avery 8000-10000 kikomiters, enjine souns good (as for disel car)

I recommend checking your oil level at 3000 miles because some vehicles burn oil. BMW and Audi especially, at 1500~2000miles I will top off.

Fuchs Titan pro 5w50

Last oil change I've decided to try what my friends run and bought FUCHS GERMANY: TITAN SYN MC 10W-40 and put 2k km on it, I'm pleased, it's nice greasy and cheap

Been running Fuchs 5W40 lately, N52 with 130k kms

I use Fuchs Titan SuperSyn 5W-40 - widely considered to be the lowest-consumption oil for the M54 engine, and it's very cheap.

BMW used to recommend you changing oil basically every time you blink, back when consumers paid for 100% of all maintenance. But in order to be more competitive, they began offering 3 year included free maintenance on all new vehicles.

I've posted my UOAs on TDIClub and BITOG. The factory fill was additive depleted at 5400 miles. The Fuchs 507.00 in the next fill was good for 7-7500 miles. It might have gone longer, but I changed it out in advance of a long trip. Bottom line is that preliminary evidence is that the 507 oils are inadequate for extended OCIs in the 3.0L motor.

Oil consumption is a common problem. My original E92 consumed a quart of oil every 1K miles. My current car does not.
