Diesel

[Devonian]

OK, so I've been a dumbass and not rotated all of my fuel stocks, I have a rogue jerry can of Diesel which is probably about 3 years old.

So the question is how do I know if this is still good to use?

Looking at it, it is still clear and there no signs of any growths or anything, so still 'looks' ok to me, but is there a way to test it? or if it is 'off' does the colour change or go cloudy??

Be useful to know for after an event as well if you have to scavenge fuel....
