Just got the change oil soon light...1200 miles after the dealer "changed" it. Im at 38000 and plan on doing OEM oil filter and fuel filters. I have had good experiences with schaeffer's in gas engine and my 6.0 but just want to make sure the 6.7 isn't as picky as my wife when it comes to lube. Any advice would be greatly appreciated, maybe even links to fuel filter replacement and oil change. More then capable to do it myself I just like to research so I don't have any unexpected surprises. Thanks in advance!
