As some have said, give it to a farmer or trucker or someone who has an older diesel with the mechanical style pump. Those are very forgiving. Fuel is too expensive to just "dump" it or waste it. Farmers and antique power equipment owners are always looking for free fuel. These new high pressure computerized systems in the new trucks are not forgiving at all, so keep the fuel fresh. Add a stabilizer too. I like Seafoam myself.
