Doesn't sound unreasonable. Let's say 50 hours, one pint of oil gained (16 oz)..
50 hrs at 8 GPH = 400 gallons. 400 oz of mixed oil. Only 4% of the oil gets scavenged into the sump. Rest is burned or goes out through exhaust.

The fuel vapors are blown overboard and only minute traces of oil are left behind. Multiply it by few million repetitions and you end up with extra oil. That’s my theory?

Bulent,

If that’s the case then, for every oz. of oil in the sump there was a gallon of fuel that went overboard in vapors with a mixture of 1to128.
