It certainly has been awhile since I checked the forum, I plan on checking it more often. I hope everyone's summer is going well.
ACTcarwashlover - I know around here (Minnesota) you can find 30W non-detergent oil at Walmart's and Fleet Farms. If your still looking, please feel free to give me a call and I can research your area of where to purchase it. Below I have added all my contact info.
at the moment it appears to be running quite well on ISO 68 oil Which is normally used for high pressure pumps here, I’ll see if I can try and give you a call later tomorrow although be forewarned that it might be at a really unusual hour due to time differences As I’m In the same time zone as Sydney Australia
