We just purchased this unit at an auction & we have been servicing this unit. The actual screw compressor itself it gives some options of what can be used for oil. It says a synthetic oil is an option (Sullair AWF (1), or SAE 10 SE,SF, SG, CD. Just wondered what others have used in the screw portion? They say the recommended change interval is 250 hrs. for the regular SAE oil & about 1,500 hrs for the synthetic. They also say that if switching from the SAE to the synthetic it would require a complete flush when switching over. I wonder if a complete flush & that waste of oil is necessary?
