Does the oil smell like diesel?

The other part of that question is "Has the quantity of oil increased as shown on your dipstick"?

I gathered that much from your first post. Are you checking the oil when it's warm? Warm oil will always seem thin compared to cold oil.

What kind of oil did you use
If you’re concerned you can get an oil analysis done through black stone

What’s it supposed to look like?
It’s a diesel. Your engine will turn brand new oil to pitch black in about 20 miles of use. Who cares what it looks like as long as there’s no coolant or diesel dilution in the oil.

Thin? How are you measuring ``thin''?
Make a little viscosimeter: take a bottle and make a small hole, maybe 1/8" diameter, in the bottom. Pour a pint of unused oil in and measure how long it takes for the pint to drain out the little hole. Then take a pint of the ``thin'' oil out of your crankcase, pour it in and measure how long it takes to drain out. If the time is roughly the same, the ``thin'' oil isn't really thinner.
Just make sure that both the used and the new oil are at the same temperature. Let both samples sit in the same room overnight, maybe.
If the used oil drains through the tiny hole substantially faster, then we can start thinking about why the oil got thinner. If you aren't getting diesel in the crankcase, it's hard to imagine that anything would thin the oil in two days, or even two months.
