Gas in Oil

[ShortlineBob]

I just changed oil on my 2018 PCM H6 engine 6.2 and found gas mixed in my oil I drain out of my engine

Is that a direct injected engine? How often do you change the oil?

Time for a compression check to see if you have some bad rings. If the compression is good you could have sticking injector or an injector(s) that is open all the time. This will allow way too much fuel in the cylinder and the fuel will eventually make it to the pan. This will also cause the engine to run rich and if so you may notice a raw fuel smell in the exhaust, white smoke at start up, a miss and/or poor fuel economy.

Having fuel in the oil is not good. If the concentration gets too high you'll get what's call cylinder wash or bore wash which means the lubrication to the cylinder walls (and then bearings) will not occur properly and well you can guess what happens next.
