Kevin,
I guess this will be one of a hundred = responses,=20 however -
1.Tracy's way of doing his PSRU is = OK.
2. Motor oils is likely to get = contaminated with=20 2-stroke oil if your using it (most are) and carbon particles from = the=20 combustion process which act as an abrasive.
3. Motor oils need to be changed after = 12 months=20 even in low use situations.
4. Heavy duty of the gears ( as in = aviation use)=20 may need pressure directional spraying, whereby most gearboxes have = splash=20 lubrication.
 
An ideal situation would be a separate = cooling of=20 PSRU oil with synthetic lube oil, with pressure fed directional spraying = of the=20 planetaries and their bearings from it's own pump and reserve/=20 cooler.
 
Just my opinion.
