What % synthetic is the synthetic blend? I have seen numbers ranging from 15% to 60% tossed around the 'net, but nothing definitive. I am approaching 2000 miles on my 2012 F250 and am wanting to change it real soon. My plan is to buy a 5qt Motorcraft jug of 5-20 Synthetic Blend from Walmart and 2qts of Motorcraft full synthetic from Pep Boys plus a Motorcraft filter. This July I will be towing my travel trailer to west Texas and want to change the oil before then.

 

Good question on the ratio of blend.... curious as well.....

 

BB, did you check to see what the local stealer charges for the change? Where I bought mine, they do it for 17 bucks and change.

I cannot even think of getting my creaky ole body under there at that price.
