when i first got mine, i read only to use PAG oil...... then i found this is the required oil when its used for a/c purposes. now, after 4 years of use, what i do is when i change my oil in my motor, i save that oil and use it in my york 210. i religiously change my oil every 3,000 miles so its not black and tar like, its still has the golden hue to it. i drain my oil trap twice a week and what drains out, i replace with equal amount. usually holds about 8-10 ounces.
