This is from my buddy's 2005 F-150 with the 5.4. He has 70,000 on the clock and this is a 6-month 5,500 run on Valvoline conventional (white bottle) 5w-20 and a Motorcraft filter. He's split about 40/60 city/highway driving and it included the first cold half of this winter.
He said that he saw some small red grains of something in the oil when draining it out. The filter has been disposed of, so I can't dissect it. There doesn't seem to be any issues though.
Comments are appreciated.
