I try to stay away from the auto fuel islands just for this reason...I'm pretty careful with details like that but why tempt fate. That would be hilarious if they had unleaded on the truck fuel islands. There would be a rash of Swift trucks getting towed off the fuel island and quitting along the highway with ruined engines. Some guys would even be putting it in the DEF tank and lighting the truck on fire.

The second of my two events including the fact that my son didn't realize what he had done until after he was sitting in the parking lot over a mile away -- the tank had been nearly empty, and he put in over 10 gallons of gas for a partial fill up, and then drove it away until the gas got into the engine, it sputtered, and then just shut down. Had it towed home and went through a thorough cleaning and purging effort before cranking it back up again. Fogged the entire neighborhood like a mosquito fogger for over 10 minutes, but it actually ran better afterwards than it had before the incident. No apparent damage whatsoever... just the pre=pump filter element and engine valley filter was replaced -- nothing else.

The truck towing mine home had 25 gallons put in it by the ranch owners kids and driven 15 miles before it died. It was new enough it went to the dealership for the fuel purging. No parts were changed and it runs fine with over 200K since that incident.
The more I read about this happening, the less worried I am about lasting damage. I'll keep the mixed fuel and add a gallon to the tank on the old tractor every now and then so it's not $120 of wasted fuel.
Thanks for all the feedback. I'll report back in a few days when it's back on the road... again....

I simply can't believe you did this. I, for one, NEVER make mistakes. Just ask anyone here....
But for real, you have a good plan. The great thing is that the 7.3 withstands a lot of our own ignorance and learning curve while we get stuff figured out. Wait until you run in out of oil due to bad injector O-rings, the engine shuts down in traffic, and you spend two days in a panic before trip replacing and diagnosing every scenario EXCEPT that one LOL....I would never do that either.....just telling the story for a friend

My 1st 7.3 and did not understand how they work, sure enough no oil on the dipstick , added a gallon and it fired right up, realized the o rings where shot!

IIRC, the first year of the Powerstroke there were drivability issues. The final fix was replace all the oil dip sticks with a shorter one that added one more quart of oil. Good to know, I'll file that no-start issue in the back of my head and forget about it until I go crazy with trying to figure out a no-start.

I was under the impression that running gas through the system on these would kill the engine somehow. I am happy to hear I was wrong.

I've never seen a pump just for DEF, all the ones that I've seen are combined with a diesel pump.
Years ago a friend of mine bought a diesel that someone gassed up and couldn't figure out what it wasn't running. Unfortunately for him, it was one of those early Chebby's and I doubt that it served him well.

I never heard of adding gasoline but I used to add about 20% K1 if I was going to shut my truck off. It returned enough to keep the tank warm when running.
