Red oil light flashes when idling

    The main cause is the oil having a lesser viscosity when heated up, when the engine is cold the oil is thicker and creates more pressure at start up than it does when hot. When the oil gets hot and thins out a bit ,combined with a low idle when stopped or turning at intersections the pressure may drop below the point that the switch needs to stay open and thus keep the oil light off, as long as the oil level in the motor is ok your oil pump will still keep sufficient pressure to keep things going till you put your foot down again ! I will only worry if it wants to stay on all the time or if your cruising at speed and suddenly comes on !
