Hi guys I picked up my 18plate bps a few weeks ago which They done a service on before handover. I checked the oil the other day on a cold engine and flat surface. And the level was well above what I'm supposing is the max level (see pic ) my finger is where the oil is up too. Im guessing either they overfilled it or that ain't the original dipstick for the car. Can someone advise please and thank you
