I am confused as to why the chart says synthetic but my owners manual says "Premium". They contradict each other.[IMG class=inlineimg]https://www.thedieselstop.com/forums/images/smilies/read.gif[/IMG]
Yes, but your Owner's Guide is 9 years old. The chart on the website is dated 6/20/2010. Apparently Ford engineers learned something during those 9 years.
