Oil is too clean?
I'm new to diesels, but recently bought an '04 F250 SD with about 78,000 miles on it. Not too sure of the service history (looks like coolant puke on the blanket under the hood but could maybe be residue from some kind of steam cleaning?).
My question is about the oil. I'm only on my second fill-up (about 750 miles on the beast), but both times I've checked the oil, it's clear enough that it's difficult to see on the stick. I have to hold it so the light reflects off it and I can see where it's wet.
My understanding about diesels was that the oil gets dirty quickly. If the window sticker is right, there's about 3,000 miles on the oil, assuming a 5,000 mile change interval.
So that's not conclusive, but is there something about the engine or maybe about ULSD that keeps it from getting dirty quickly?
