Fellow 6.7 owners, In April, DW & I purchased a 2015 F250 with the 6.7 diesel. Gotta say I love how it tows our trailer. Goes down the road like it is not even back there. My question is about...
I've had two 6.7s and they seem to go along way between regen. One thing I noticed, and you can call me crazy, but when I bought the 2011 it had a number of free oil changes, so I used the regular Ford diesel oil. After the program was over I went to Mobile synthetic for diesel, 10 w 40. I noticed right off how much further I could go without needing to add DEF.
