Engine oil FUCHS or OEM Subaru

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.

Fuchs Titan 5w30

Well, some manufacturers do have way shorter oil change intervals than Euro manufacturers. The Subaru severe driving interval is 3000miles/6 months, and I do lots of short trips in a desert climate so I usually try to be around 3-4000 to stay on the safe side for warranty and whatnot.

My experience with oil consumption - 5W30 VW - First oil used by me in this car - 2000km - 200 ml added 5W40 Fuchs Titan Race Pro S - Now in the engine - 1000km - Same level as it was at the revision

Fuchs Silkolene. Good stuff.

My 15 S4 has seen 3 oils in <10k miles. The factory fill was Fuchs. Dealer first change was PP Euro and my latest change the other week was with M1. I've run M1 0w40 Euro in my B5 forever and have had 0 issues with it. Saw no reason to not continue running it in the B8.

Dark oil is actually a good thing believe it or not. It means that the oil is doing it's job and holding all the contaminants in suspension. In fact if my oil would look clear at the oil change I'd be very concerned and most probably change the brand.

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.
