question for guys who use older dair pumps. mine is a bb4 piston pump. i usually use tractor supply dairy pump oil, but haven't been able to find it locally so i got a different brand (can't remember the name). i changed my oil yesterday. it looked ok, but figured i'd change it before it warms up and the sap starts to really run. the new oil seemed a little bit thicker. filled up the pump and ran it for 10 minutes and noticed it started looking cloudy. so i figured i must have had some water in there, however the old oil i had just drained didn't look watery at all. refilled the pump with the new oil again, and same thing. cloudy/a little snotty looking. I repeated the process one more time. i didn't have any more oil after that, so i figured i was at the sugar house and i'd let it run and keep an eye on it. within probably an hour, to an hour and a half the oil clearing up and looked "normal/clear". any idea what's up with that? could the oil be to thick or perhaps the wrong type of oil (it says it's for piston and vain pumps)? no sap in my moisture traps and the old oil didn't have any frozen on top of it... so i'm doubting i have sap/water in the pump, but i guess it is possible?
