I am running for the most part Cat pumps at my Wash's.. Just curious if there is a recommended maintenance schedule / Oil Change Add Frequency that anyone can recommend.

They run like champs.. Just don't want to ever be without them.

Oil change is every 500 hours or six months, whichever comes first.

I've gotten fed up with washed out manifolds, so I replace the seals and valve o-rings once a year before they have a chance to go bad and cause erosion.

Other than oiling the wicks on the pumps that have them, there is no other maintenance.
