is petrol as unique as a fingerprint?
Out of curiosity, I have heard petrol has trace of it from where you brought it. But I've wondered if the trace within petrol is unique enough to tell exactly where it was brought from right down to the exact forecourt it came from or is it just specific enough to tell the place that sold the petrol in the first place ie tescos, sainsburys, shell etc.

When you add petrol to the tank it mixes with whatever was already in there - no way to trace that mix.

Petrol comes from refineries. There is a huge one near me in Fawley, Hampshire (co-incidentally on the news today due to theft of fuel). All the petrol retail firms in Hampshire and surrounding counties fill their tankers there. So it doesn't matter whether it is Tesco, Asda, Esso, BP etc etc they all sell the very same fuel. People who believe there is a difference in the fuel at filling stations just have no idea. So, you may be able to identify the refinery's fuel but not the filling station's.

It's traceable to the retailer but not a specific site.
Individual additives which petrol retailers use are added at the point of loading the tanker at the terminal.
