I have a 1996 Roadsport with a k series supersport engine. I have changed the oil using Mobil 3000, 15w 30 fully synthetic, filter and foam sump insert. When the car is running hot the oil pressure drops to very near the red mark on the gauge on tick over then moves to around 2 bar when running at normal road driving is this ok ? Im driving to Italy this summer and it worries me!
