Since I went to Synthetic my Massey is losing power. I have one steep hill to mow, I mow at 2,000 RPM, this afternoon I mowed it and the best it would do was 1,300 RPM. Opening the throttle makes no difference. In the past it would pull this hill without breathing hard. On the flat she's back up to 2,000. The only thing that has changed is the oil.
