if it's a 2.2 crd it takes 7 litres of semi sythetic ( diesel oil ), it's recommended that within Europe the oil meets the standard of ACEA B3 or B4, it should mention this somewhere on the label. Always change the filter too, or 7 Litres will be too much! hope this helps.... Andy

It is important to use the right type of oil in a car to help it run at its best. The PT cruiser vehicles are known to use 5w-20 engine oil.
If your owners manual is still with your Cruiser, check in it. It will state what type of oil to use.
