Hey there, always enjoy your videos. What kind of pump oil do you use on the Simpson Aaa triplex pumps? They call for 15w40 but most oil and pumps call for 30 wt non detergent, which is cheaper and more readily available. Thx
Thanks for watching. So from what I remember the Simpson Aaa are 15w30 non detergent so you can buy any non detergent weighted oil from the auto parts store. I would use what the OEM recommends. I only buy the "pump branded oil" if it's on sale and is the same price as a weighted oil that is recommended. Usually Walmart has the best prices on oil. I hope that helps.
