What kind of pump oil for simpson gcv190

Most of the time but not ALWAYS...30 weight Non detergent SAE is used in most pump but on the smaller engine Hondas as well as the larger pumps such as the dual pumps that run automatic car washes take a special gear oil or hydraulic oil....This is why I asked for the model of the pump. It is not always safe to assume it is 30 weight non detergent. I have repaired too many from people putting 30 weight in and it being the wrong oil.

Hello Jeff, (I commented/replied earlier, but don't see it?) Anyway... Thank you for that info! I have learned something today. I truly appreciate folks like you that share their knowledge, and will offer correction when deemed necessary. And I, always welcome correction if needed. I own multiple washers both electric and gas, hot and cold, 1800 psi / 1.5 gpm to 5000 psi / 5 gpm and I add Non detergent as instructed to all of them. Once again, thanks for the clarification.
