Default Gasoline in crankcase oil

At my last oil change I had an oil analysis done. It showed gas in the oil. Where are the places I should look for the infiltration? Could it be coming from the mechanical gas pump? I have no gas or oil leaks on the outside of the engine.

Normally that means the fuel pump has an internal leak. Change it out and change the oil and filter again

could also be from running too rich, wipe your finger in the tail pipe, do you get a black non oily film on your finger tip?
Does your fuel milage really suck?
Is the motor hard to restart when fully warmed up?

I would check compression on all cylinders. Worn rings can allow fuel bypass on the compression stroke, especially if it's running too rich.
