We have Motorcraft 5W20 oil in both vehicles but next change will use Havoline 5W20 Synthetic that we bought on sale at Big Lots. Main reason was the sale. Other than that have had good luck with the Motorcraft oil

As someone who has run BOTH Syn and Conventional in the SAME engines and HAS run UOAs for both oils, I am running conventional due to a better (lower) wear metals and cost per mile.

There are enough Amsoil websites on the web without making this a mouthpiece for a non paying shill. I am sick of it.
I'm sick of it as well.
Tim, Amsoil is a very high quality oil, however, it is not the only one. The gap has closed since SM came along. There are a few UOA's that show decent results with Amsoil at longer drain intervals, but most are not that good.
Nothing wrong with using an API SM oil changing it every 7.5k miles.
