10 year old petrol?

I would drain it out.

That sounds like better value for money for me Fuel would've been cheaper then, so will go further

the fuel came with the car

The Midas had not been on the road since 2000. When I removed the tank, it still had 7 1/2 litres in it. Works my Dad's chainsaw and my Father-in-law's lawnmower just fine

Looked like this:

It tends to polymerise with age, i.e. small molecules join up to make large ones, so it goes thick and gooey, and gums up pumps and carburettors. What you actually need to worry about is the contents of the pump, carburettor and fuel lines, as they may be almost solid, and will need to be stripped and cleaned.

If the fuel in the tank is still thin and runny, and not full of water or rust, it will be ok, once the rest of the system is cleared out. If there are signs of water, add some alcohol (methylated spirit) which will dissolve the water, and the resulting mixture will be combustible. Not on injection models though, as I hear that some seals do not like alcohol.

It also oxidises as you can see from the photo above, it is quite a lot darker than fresh fuel

Oxidation, rust particles, or both? Definitely a bit off colour.
