I’m just wondering what you guys think would be the better of the two for use in the Ford 4.6.
I’ve run the MC 5W20 Semi-Synthetic in my 05 Police Pkg Crown Vic since new (3K OCI‘s - car currently has 55K miles) with excellent results, however, the current sale at NAPA has me considering giving their 5W20 Full Synthetic a try.
The NAPA specs look good but there doesn’t seem to be any UOA’s with the NAPA (or Synpower) 5W20 posted.
