go to
cat pumps website like I described above for you. They call for 4.2quarts of oil and I personally would look at the rear sight glass on the pump there's a orange dot halfway is where oil should be when level. Drain and fill with 4.2quarts to start. This is one of the easiest things to do at a Carwash. I personally would run factory cat oil in a 5K pump and wouldn't want to risk damage because I was to tight to spend $100 on the correct oil. Hope this helps.
Home Depot Cat oil 21oz bottle each= $9.98
4= quarts = 128ozs
buy 4 21oz bottles should be $70 should get you real close. Cheaper than
kleen rite with no shipping or wait time. Just saying.
