Engine oil PETRONAS or Motorcraft

I run motorcraft in my mustang and have zero complaints.

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

Petronas Syntium 5w 30 on a mercedes and audi a6. No complaints at all, and good price

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

The 5W30 full synthetic engine oil works the best for a wide spectrum. Its working temperature range is practical for daily use and it costs less than 5W40.

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 giulietta 1.4 MA is still reliable at 130k km. Never had any problems with engine always used recommended petronas oil. Had to rebuild my turbo once (at 120k km) it had very little play that made my car burn some oil.

found some FORD Super Duty Diesel oil 15w40.....seems to work pretty well! ford aka motorcraft

ive always used motorcraft diesel oil. 10w30 in the winter and 15w40 in the summer.
