I've checked the under cap, nothing built up as my 2015 had "milky" residue often under the cap but no engine problems at all for the 40k miles I had it. I know oil expands and contrats depending on heat, as I said to Zig, I just wasn't sure if there is coolant mixed in, if it'd be easier to see on the dipstick when the oil is completely cold.If you're not already familiar with the characteristic, oil will expand when hot and return to normal once cold. You're dipstick will measure differently. Mine moves as much as two "X" up and down the scale.
In addition to the dipstick, you could remove the oil fill cap and take a look at the underside of it. But this can sometimes be deceiving. Milky-looking residue can accumulate, depending on how the car is driven, season and temps.
