***OIL PRESSURE WARNING SOLVED***BMW E90 with same issue. Intermittent Oil Pressure Warning light for around a year. No performance issues or strange noises.Started when slowing down coming off highway and then progressed to when driving around town as well.Tried a can of Wynn's Super Charge Oil Treatment and after a few days light stopped coming on around town but still after highway driving. Bought another can and poured that in and six months later no warning lights. Guessing will have to do this again after next oil change but so far so good. Car running and sounding better also.
