Petroleum is a fraction of crude oil obtained via fractional distillation. It can also be obtained via 'cracking'( splitting the molecule of a larger fraction to gain more, smaller molecules). I do not think you can make synthetic petrol as synthetic means man-made which usually means plastics. I do not think petrol can be made from monomers and polymers.
A Volkswagen Golf Mark 3 N Reg should take 15w40 oil if the oil is mineral. If synthetic oil is preferred, a weight of 10w40 is fine.
5w30 full synthetic. i prefer Mobil 1
