Engine oil OEM Subaru or Motorcraft

OEM Subaru Engine oil

No issues with 5w-30. Switched my 21 Crosstrek to it due to the summer months coming. Little dip in mpg but the engine runs smoother.

Pros: engine runs smoother
Cons: little dip in mpg
Vehicle: Subaru

Motorcraft Engine oil

Rating 5.0

Full synthetic Motorcraft for my Shelby, Roush, SHO, and Focus 1.0 ecoboost.

Ford performance oil filter for the Shelby. Motorcraft for the others.

Why? I had a Ford tech tell me any and all problems they'd ever seen with a Shelby engine involved one that used non-Motorcraft brand in engine or filter.

Pros: no problems with engine
Vehicle: Ford
