Just changed the oil in my 18GK engine for the first time since it was rebuilt. It only needed 3 litres of oil to bring the level up to the full mark on the dip stick. The manual has the sump holding 4.26 litres, filter .57 L and cooler .42 L. Is my dip stick the correct one?? It shows the oil level as 9.5 inches down from the top of the dip stick tube.
