Diesel Freshness

[Barchetta]

How long can diesel be stored with a stabilizer added to it?

Background - I am getting a hot water pressure washer that is going to use diesel for the burner. I will not be using the burner on a regular basis so I don't want to have diesel that's going to go bad on me.

Any thoughts or ideas?

I had a couple 55 gal drums of red-dye sit for about 6 months before we used them and I didn't notice any difference,

how bout a 500 gallon tank??? I'm considering it when I move back to the farm since I can get it delivered at that days prices with no charge to use the tank, then use it for the next 4 months or more until I need more. Would be nice considering I'll be driving an hour each way again and fuel prices seem to only be going up, but wouldnt be for me! (Not to mention I could be running farm diesel.....if I can get a locking fuel cap and maybe fuel door, then "forget" my key at home with the tank!)
