I hit 5000 miles and 8 months this weekend since my last oil change, so I figured I'd take advantage of the mild temps to do a change today, since I had everything at home to do it.
Last change was in May, 109200 miles, first one oil change for me, as soon as I got it home. New OEM filter and Amsoil 0-20W "OE" grade oil. I check it every few weeks, it never moved.
At 114200 miles now. Warmed it up for a few minutes in the garage, then dropped the shields and pulled the drain plug. Oil was dark as expected, otherwise looked normal. Then I removed the fill plug, and found this:
That goo went all the way down inside that plastic fill riser. I pulled the engine cover, and removed the riser. You can easily see down under the valve cover with that off, I saw no more evidence of that residue anywhere, it all looked normal for that many miles. I drained the oil filter into a separate clear pan, let it sit, saw no milky oil, water separation, or sediment, it looked normal, as did the oil filter.
This truck has never used coolant, the last time I added any was last fall when I had the water pump changed (preventive), and I have a mark on the reservoir at the level when cold, it's never moved. It has never smoked or had a steam cloud out of the exhaust. Engine runs very smooth. I also had the plugs changed when I did the water pump, they looked normal but worn out, they must have been original.
My commute is 8 miles, and I occasionally let it warm up before leaving, especially if it's really cold. I scooped as much of the goo out on a blue paper shop towel, and you could see it wicking water out into the towel. Plain water, not pink. Then I cleaned the rest out with brake clean.
Hoping this is just condensation build-up from not running long enough, as has been posted here before. Seems rather excessive to me though, I'm kinda freaking out. I'll check it every time I get gas from now on, might do another change in 1000 miles just to be safe. Maybe I'll find a longer route to work.
