I have no idea what it is or what it contains. I can't locate it on a web search.

Oh, sorry, I just found out it was DEF or diesel exhaust fluid I put into the fuel tank. Any help would be appreciated!

2 and 1/2 gallons
Once we realized what I did, we drained most of the tank and then added 10 gallons of diesel. We changed the filter and it still wont start.

Was it run with this stuff in the tank?

Oh. I just read more of the fact sheet and this stuff is supposed to be injected into the exhaust stream before the catalytic.
