Spooge from certain oils is not necessarily a bad thing. It shows that oil is migrating completely through the motor intact. It's not burning in the motor, so therefore not leaving carbon deposits behind. From my experience with Amsoil Dominator, a high flashpoint oil, PV parts and exhaust port surfaces are little more than stained, and can be cleaned with a rag after many hours of run time. Really the only negative is faster silencer packing saturation, and more so with a spark arrestor type. Longer cans like the Stealth are worse. To me this is a non-issue, I happily repack knowing that the motor is well lubed, clean, and the PV will not stick. JMO.
