What do you add to diesel fuel whenit is old? My husband added something to it once because the coach sat for a while.
There are additives that prolong the storage life of diesel, but they must be added before you store it.
Not sure what you can add to "restore" it after the fact.
How old is it?
Has it been stored with the tank full (to minimize condensation)?
Does it still smell like diesel? If not don't use it-- diesel injection pumps and injectors are expensive!
It's been about 10 months. Haven't smelled it yet. Does it smell like normal gas? Sorry' but my husband passed away and I need to get it to Motorhomes of Texas tomorrow.
I don't think 10 months is "too old", but Brett W. may know specifics.
Drive it. My sailboat used diesel waaay older than that.
If you find you need help with it, you can either post where you are, or PM (private message) someone in the same city.
Many of us would be happy to help.
1 year old diesel fuel is as good as what you buy today, when it has sat 10 years, then you think about the issue.

Thank you everyone! I feel much better about getting out tomorrow and driving it again. I miss it! :)
Those additives are to prevent any possibility of algae growth plus add stability to ultra low sulphur diesel fuel. The ULSD with 15 ppm sulphur will only remain within specifications for 3 to 6 months. Does not mean that it won't work but the emissions will be higher because of the ingredients used to replace the sulphur have a short life.
I have used 20 year plus old diesel and the engine ran OK. The bunker oil used in diesel engines in big ships is not that much different than some really high grade crude oil that has been in the ground for millions of years.
