Wife drives a 2014 Lincoln MKZ, that uses the 5-20 ''Motorcraft'' as she has the dealer service it every 5K miles per Lincoln. [ 3.7 v6, 6 qts. ] I recently got a new 2016 F-150 5.0 and it also calls for the 5-20--every 7,500 miles. This one lists 7.7 qts. capacity, so I will probably actually go the 7,500 miles between OCI and I have always read good ratings on the ''Motorcraft'' oils, just wondering who actually makes it. I am also ''old school'' and will most likely do the first change at 1,500--2,000 miles.............always have.
