Good afternoon, fired up the +8 for the first time in a few months today. Did the usual oil level and coolant checks all ok. Started almost immediately, allowed it to run for a few minutes to warm up but noticed the oil pressure was just above the zero rather than the 2+bar it usually is during warm up. Could possibly be the gauge, looked behind the dash and nothing seems out of place, the gauge does move slightly when I turn on/off the ignition? But want to be 100% sure before I take it for a run is there a way to check oil pressure/flow? Appreciate any advice on possible causes and actions to take - thank you!
