As many of us do, I'm always researching oils for my car and truck. I'm looking at different oils for my 2013 F-150 with the 5.0. Owner's manual calls for 5W-20 synthetic blend. My research found me many options, on top of the Motorcraft blend I've been using. My truck has a little over 50,000 miles on her. I came across Sunoco's Ultra Full-Synthetic and Ultra Synthetic Blend oils. I can get a case locally at a great price. Anyone offer input on the Sunoco line of oils? I have been doing 7500 mile OCI with the Motorcraft oil filter. Thanks!
