I have a 2018 P500 with about 2000 miles. On my last ride (about 500 miles) the first day we rode about 75 miles and I burned about 1/2 quart of oil. When engine braking down moderate to steep hills I did occasionally smell oil. I checked the oil on flat ground and refilled to the full line. Over the next 5 day and 425 miles the P500 didn't burn anymore oil. Has anyone ever heard of an engine start burning oil then stop burning. Can an oil ring get stuck then unstuck? I checked the airbox and didn't find any evidence of oil getting pushed through the crankcase ventilation hose/PCV. Are there other possibilities for oil burning?
