S4M31 Posted May 16, 2021 Report Share Posted May 16, 2021 I bought a 2900 psi ryobi pressure washer recently, and added some high quality sae 30 oil like the manual said (the oil was a little old but seemed fine.) I ran it once for about 15 mins, shut it off. Then, came back the next day, and ran it for about an hour, shut it off and checked the oil. The oil was a good bit lower than it was when I added it. It showed no signs of burning oil at all when running. Started up a bit rough, but ran fine and didn't smoke at all. What would be causing this? And is it a big problem or should I just top off the oil? Quote Link to comment Share on other sites More sharing options...
