I'm told it's the same stuff, except it has the sulfur, and it has NO injector cleaner.
It WILL clog your cat, if you have one.
Reason they started the dye was, in the 1980's there was a lot of truck stop owners buying this, and selling it as diesel. Many owners got rich on this. Plus the Govt. don't like it when you dont pay taxes.
If you go to a plumbing supply house (not Home Depot,go where the contractors go)ask for fuel test paste. (I dont know the real name) It's in a small tub. You smear this on a woodn stick, and push it in the tank till it hits bottom. Pull it out and see if it turns green (I think) it'll say what color to look for on the tub.
This will tell you, at least if water is in there.
They do make special additives to remove microbal growth. If it looked like it might have this, I definetly wouldnt use it. MAYBE in the house, depending how bad it looked. If it's real cloudy, it may have growth. The only way to tell is to send it out to be analized.
I've worked places where they had #2 oil sit for 5 years, and it still fired. It was probibally pretty crappy by then, but it worked.
