Pressure Washer Pump Ouk

[Chopper007]

Ridiculous! I have called Royal Purple Compressor Oil Company,also PowerMate Full Synthetic Heavy Duty. Royal Purpal didn’t know squat, PowerMate had me on hold for 45 minutes before I hung up. Also called Simpson which is what this question is about. I have a Simpson 3.5 gallon a minute with 4000 psi washer doesn’t have squat on the info of the pump which they state only use 15w-40 I live in Florida so in my equipment I use Royal Purple and or PowerMate full synthetic I just wanted to know if those are good oils to use with the AAA or FNL inc. pumps? So much **** is made in China and these sale’s people are working and selling a product they know Diddly Squat about! So just want some input? The oil they promote gets dark in a few hours of use! I can’t be the first guy on here who used a higher refined synthetic on his equipment, my outboard gets treated with AMS oil runs great. Sorry for the long question, I just spent 2 hours on the phone with 3 companies who don’t know about what they talk about or selling.

I just run whatever flavor 15w40 i have on hand and change it after 20 hours. Never had a pump failure.

Thanks bud, but I was hoping someone has used 1 or both of these oils I always use. Both of them work great in my compressor’s it gets hot down here and never had a problem. Now I am new to pressure washers and the little homework I’ve done, these Honda engines are great but there is some mixed reviews on the AAA pumps.
