Re: 318 and 44 loader: hy-gard or low viscosity hy-gard
PA318 is correct use the low viscosity. Make sure you clean the filter well, and get all the gunk that settles below the filter. I used kerosene and and oil change pump to clean it all out. I think you will find that the milky oils is coming from an air leak.I thought it was water in the oil, but after changing it, the new oil got milky right away. My 44 was leaking at the intake to the pump where the return hose meets the pump. sucking in air frothed the oil. Let us know how it works out....pictures?
