Thread: What colour is diesel?

That looks more like filtered waste vegetable oil than diesel.

How old is the fuel. Looks like it's been sitting in there for a long time.

Fuel looks like it's on the way out due to bacteria. Treat the tank with a fuel biocide to stop the bug from growing.

Car is of unknown providence. Not sure how long it has been sitting. I am doing a full rebuild so the system should be cleaned and recharged. Actually smells more like a n m113 bilge

Off diesel has a peculiar smell, like old mineral paint. Good diesel should look like a light beer, not dark like a heavy beer.

Old diesel seems to change it's smell a bit but it still burns fine unlike old petrol. I would try it first before ditching it.

I wouldn't chuck it. I'd strain it through a medium mesh and mix it with some new and re-use.

Years ago I bought my diesel in bulk (44gal drums). It seemed oily to the touch and honey coloured. Now it seems as thought it is "watered"down, thin and colourless.
