Normally oil leaking from the top of an engine is a sign that you have a leak at a valve cover. The cover may be loose or the gasket may be defective. Tighten the valve cover bolts to no more than 5 lb/ft of torque. If that does not stop the leak, the gasket will need replacing.
About 4.5 liters.

depending on the engine size it is about 4.5 litres of 10w40 , i would recomend a least a semi-synthetic oil , as this leaves a nice coating on the internal parts of the engine and reduces wear and damage when engine is cold
