Diesel

Diesel
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....

RE: Diesel
divide it up into a small part of the newer batches.....at work we have back up generators that are only fired up once a month for 20 minutes as a test and some of those tanks haven't been filled/topped up for over 20 years.
Nothing is fool proof for a sufficiently talented fool!!!!

Thanks and yes despite what some think, it always puts a smile on your face when driving it.

RE: Diesel
In older cars ,you can run them on any thing ,but the newer car have sensors to check the fuel ,the new pumps don't like change,so it could cause a prob just not worth it .but yes you could mix it with new fuel

RE: Diesel
cloudy / milky or black slimy bits is anaerobic bacteria which can clog fuel filters, a drop of gasoline or acetone in the jerry can should help the cetane level. or you can simply blend it 50 n/50 with fresh diesel. crap diesel may also show signs of lacquering eg a hard varnish like coating on the sides of the fuel can.

Fuel stored in sealed containers like good quality jerry cans ( with NATO spec coated insides) should not be able to absorb moisture or air so any growth will be anaerobic and less messy than aerobic fungus mould, diesel is not as refined as petrol and has less volatile organic compounds to settle out or evaporate, I would just mix it with fresh diesel.

RE: Diesel
if you are in any doubt I would ditch it, you don't want to bugger up your engine, its not like its post SHTF and you don't have access to fresh stuff.
Some people that prefer to be alone arent anti-social they just have no time for drama, stupidity and false people.
