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....
So many vehicles go into Jiffy Lube or Rapid Oil type places and just get whatever they have on tap. I'm not so sure if they even know what they have. But a clean oil change is most likely better than some that rarely change their oil at all.
Just my thoughts, Brian
