Engine oil FUCHS or Motorcraft

I ran motorcraft for like 70,000km's and switched to amsoil 5w50 after that.

Fuchs Titan pro 5w50

I’m using Motorcraft 5W-20 Synthetic Blend in all my Panthers with 2500 mile change interval and no issues.

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.

Mann filter.

Fuchs Titan 5w30

I was having some issues with shuddering when the engine warmed up. Put in Motorcraft 5w20 synth blend in my 2015 XLT 5.0 and it’s been running like a champ

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

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.
