When I look in my oil cap is has a milky substance

That is usually caused by the crankcase vent being plugged, so check the venting system then usually changing the oil a few extra times will clear it up, also run a good grade of engine oil, one made for air cooled engines. I think Autozone folks were thinking of what the used car guys called lot rot, it was from just sitting on a lot and just getting started up and ran for a few minutes then shut off.

I got this in my old beetle when I used Pennzoil- there is some kinda wax in that oil- it went away when I started using better oil like Valvoline or Castrol- it may take a coupla oil changes to disappear completely- your air cooled engine must have more frequent oil changes because the oil is acting as a coolant- so keep up on the maintenance- like checking that crankcase vent- and the oil filter- etc. etc.
