    X758 Diesel

    Stupid me, before I knew what I was doing I poured about a quart-plus of regular gas in the almost empty tank. Dealer advised to drain tank but said probably wouldn't do any significant damage. So I went ahead an filled up the tank with diesel including the JD C-tain additive. But still wondering if anyone has done this and if their is anything to worry about. I can still have the tank drained if advisable but its a mess doing it and if the risk of damage is next to zero I'll just run the tank till 1/2 empty and then refill. Any one have any comments besides the fact that I'm a dummy??

    If I were in the same situation, I would drain all fuel out of the tank, fill 1/4 full with diesel, then remove the feed line coming out of the tank. Get the in-tank pump to pump fuel out of the tank until you get diesel coming out of the line. Shut the pump off, reconnect everything, add a good lubricity additive (double dose) and motor on. Remember, diesel acts as lubrication for the pumps. Reduced lubricity from gas mixed in could shorten the life of your pump.

    Define "quart plus". I might not worry about a quart in 6 gallons but much more and id $h!can the whole tank. For $20 its not worth it to me.

    Well, quart plus is the best estimate of how much gas I dumped in before I realized what I was doing. Could be more though. I think what I'll do is get a transfer pump and suck the tank as dry as possible and then refill with fresh diesel and the JD additive. At least that way I won't be worrying about damaging anything, the cost of the fuel is not an issue.

    With a bit of diesel fuel additive I think you'd probably be OK to run it. For piece of mind you should probably drain the tank. I wouldn't go beyond using a siphon hose to drain the tank. I keep a jiggle-ball hose around just for this purpose.

    I topped off my front axle with JD premixed coolant one time. Thought I grabbed the HyGard, but I didn’t. Probably didn’t put in enough to make a difference but I immediately drained it and refilled with fresh oil. Piece of mind goes a long ways. If you think you are going to worry about it, change it and sleep well.
