I presently own a 2003 Honda Civic and 2003 F150 w/ 5.4L engine. 5W-20 is the factory recommended oil for both vehicles. I anticipate putting 25,000 miles per year on the Honda and 10,000 miles per year on the F150. Could someone recommend oil and oil change intervals for me based on my usage? I have been using Motorcraft 5W-20 in both vehicles due to its availablilty, but is there something out there significantly better? Thanks.
