R300 k-series, not had the car long, been out today, and noticed the oil pressure at about 30 mph in traffic is only about 2 bar or just over, much the same at idle. Once I got up to about 50 - 60 mph it goes up to about 4 bar, it's the low reading I'm wondering about is that correct. The car has an Apollo oil tank if that makes any difference? Simon.
