Handbook shows oilpan capacity with filter as 6 quarts(5.7 liters). Before changing the oil I warmed the engine and then drained the old oil and removed the filter. With the engine cold put I in the new oil but the most it would take when the oil level was at full on the dip-stick was 4 litres. I ran the engine and checked level when it was cold and the level was the same. As far as I know the difference between US and UK measurements would not account for the difference. The old oil which I drained was 4 litres. Any info' appreciated.
