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.

no
Petrol is made out of crude oil which is a natural resource. When the crude oil is refined, petrol is produced in addition to other by-products like diesel.
Is a combination of oil product such as diesel and petrol
Provides petrol for cars!
it is a bad thing of oil
Yes, but you do so at your own risk. If the manufacture recommends synthetic oil they have a reason for doing so. Turbo engines, or high performance engines benefit from the use of synthetic oil. My advice is to use synthetic if that is what the manufacture recommends.
Synthetic 10w/40.
Use only what the manufacture of that diesel recommends.
3liters of synthetic oil 10W40
You cannot tell by looking at the oil. Owners manual will tell you. You can use synthetic even if it came with conventional. But if the manufacture recommends synthetic then by all means use it.
10w 40 semi synthetic is what you need
5W/30 Semi-Synthetic Multigrade
NO!
10W40 semi synthetic.
Answer1.4 petrol engines are listed as 15W/40 semi synthetic 1.4 Diesel engines are listed as 5W/40 semi synthetic or 5W/30 fully synthetic
There are a few different engine sizes in the Nisson Almera petrol range but they all take a Semi-synthetic 10w/40 Engine oil.
