I have been using Motorcraft Semi Synthetic 5w-30 in my motor home(Ford V10 - 1999)for several years. I am considering changing to Walmart,s full synthetic. Price is nears the same. Any thoughts....

I use Motorcraft 5w/20w Semi-Synthetic in my 2005 E-450 6.8L Fleetwood.34,000 miles. I use Motorcraft 10w/30w Semi Synthetic in 1995 F-250 7.5L 198,000 miles (leaks more than it burns) I have never used anything different. I even use the 5w/20w in the Onan Microlight Generator. Let the flaming begin.
