Diesel in Gas engine
my supercrew ran outa gas, someone game me a tank of fuel, said it was gas, but was diesel, I put it in, definitely put in less than 2.5 galon, probably around 1.5gal. Should I let ford fix it or can I put in high grade gas and start it, people told me i could do that. If putting in gas is ok, how much damage will that make to any components? Thanks.

You will experience some sooting that will disappear after a few tanks of gasoline are burned through the engine. The diesel fuel will drop the octane of the gasoline quite a bit so be certain to use the absolute highest grade you can find. Fill with as much high octane gasoline as you can get into the vehicle and then run this tank as empty as you feel safe doing without running out on the motorway. As for clogging a fuel filter, this is not a issue in the least. If your machine uses paper for the gasoline filter then the diesel will cause absolutely zero problems and will pass through the filter unnoticed.
Good luck with whichever method you decide.
If you don't pump/siphon the diesel out it would probably just smoke a bunch and carbon up the cylinders and the EGR valve, that is true, but if you put gasoline in a diesel you get the same as a very low octane condition and get alot of knocking, eventually you get piston damage if it is bad enough..
High octane is like HEAVY fuel, it needs LOTS of air to burn and does not ignite quickly, but does burn hotter..
Low octane is like LIGHT fuel, needs less air but does not generate as much heat either....
Kerosene and diesel is a heavy fuel compared to gasoline, and they both act like a high octane fuel compared to gasoline, they need more air and more UUMPH to go bang, and in a normal gas engine they will cause a RICH condition (soot-unburned fuel) if there is enough of it in the gas.
Either way if it is diluted the engine will handle it, but generally you want the lightest gas you can get that does not knock too much..
too much knocking is damaging, and too heavy fuel is just causing more soot, because the air mix can only burn so much fuel...
High compression engines (diesels..) need higher octane grade fuels to prevent pre-ignition, and usually that higher octane grade fuel is considered lower grade fuel (less refined)

You should be able to get most of the diesel out by a simple siphon. Then fill the tank and you should be fine.
I'm a bit surprised the diesel pump actually fit into your truck's filler neck. The guy must have tried pretty hard to get it in there.
I don't mean to be impolite by disagreeing with you but your information is slightly wrong. Diesel fuel is known as a heavy fuel because it carries 16 carbon atoms per chain as opposed to a higher refined gasoline that carries 8 carbon atoms (hence the name OCTane).
This is the reason gasoline is so much more volatile and has such higher aromatics.
The part that I disagree with you on is this:
"High compression engines (diesels..) need higher octane grade fuels to prevent pre-ignition, and usually that higher octane grade fuel is considered lower grade fuel (less refined)"
Octane pertains to gasoline and not to diesel fuel. Octane is the gasolines resistance to burning - the higher the octane, the slower and more complete the burn and the less likely the fuel is to "pre-ignite" before you would want it to.
Cetane pertains to diesel fuel. A higher cetane will provide a more precise timing of the fuel combustion especially at start-up on cold engines. The diesel engine works on the principle of "pre-ignition" on a system that has no "post-ignition". Diesel fuel has absolutely nothing to do with octane and the high compression of a diesel engine should not be compared to a high compression gasoline engine.
used to be that some garages would actually recommend putting a pint or so of diesel into a full tank of gas as an upper lube. since the fuel filter changes were done every ten thousand miles, a disposeable element inside or just in front of the carb, it was a no-brainer cheap change. so nobody ever noticed the candle wicks and sludge in the fuel filters from diesel. of course, that was back when Dinah Shore was still on the air.
The octane rating of gasoline only refers to 2 compounds, normal heptane and " iso-octane " or 2,2,4-trimethyl pentane...
I was saying that the higher compression engines need the slower burning fuel in order to start burning at the right point in compression cycle, the lighter componants in the gasoline will start burning earlier under those conditions and cause the knocking which would damage the engine. I should have said that the diesel needs the higher WEIGHT fuel rather than higher OCTANE...
As far as the Diesel fuel in the Gas tank, I agree with MR_Shiftright about the Diesel nozzle should not fit in the gas tank, but if it was just pumped out of a drum with a barrel pump...
see y'all
If anyone wants to read some cool pages on gas grades, here's a couple:

It was interesting reading back on some of that material, kinda made me think back to some of those classes....hmmm....what else can we talk about
see ya!

note: that 2nd one you have to copy/paste the whole thing, it wierded out on me
The opening in for the filler on the diesel vehicle is made very small so that you cannot accidentally put gasoline into a diesel tank. As Swschrad referenced above, that is a very explosive mistake. Gasoline in a diesel engine can blow up real nice.
Since the diesel opening and nozzle are very slim, the nozzle will easily fit into a gasoline filler tube.
I am also of the thought that the diesel in the gasoline tank will not hurt. It will lubricate the upper end of the engine for a change.

My tank is 25gal.
It wasn't at the pump. The truck was on the highway, we got a ride to the station, wanted to buy a gas tank, lady said they didn't have any but for $20 we could use theirs, so she gives us their can, it had fuel in it, we asked if it was unleaded, she said yes and we dumped it in.
Thanks.
They should pay you. It was their fault, 100% slam-dunk their responsibility unless the can had DIESEL written all over it (doubt it, huh?)
This is just not a big deal. He needs to learn to take his lumps and move on. You shouldn't call a lawyer for everything. Take some responsibility.
I also don't like people who blame everybody else for life's little knocks. Bugs me, too. But this doesn't fit that category, in my opinion, because it appears that he was mislead by negligence.
You'd figure somebody working at a gas station handing you a can of gas, well, then it probably has gas in it. In law I guess this falls under the "reasonable man" idea.
How about "oh, yeah, that fire extinguisher is full charged, you can count on it" and your car catches fire and Cool Whip comes out? I think you'd have a case.
I watch a TV court program once in a while. Did take two courses in business law. Most of what I remember is that the test cases were almost opposite of what you thought was just. I am a technical consultant for a lawyer and get about two calls a week (which means nothing). We do talk about interesting aspects of the law now and then. Can never get a straight answer out of him. He says going into court is always a crap shoot and "How much justice can they afford?"
Mostly, I can still remember what it was like to be young. Impulsive, impatient, far too trusting, with periods of impaired judgment, and an undying belief that someone else would make it all better. This is the first time most of us sort out life on our own. Some of the things I did defy explanation. I just think the real story, if you could ever get it, would be quite interesting. He could always get me as the judge. Remember, you never learn anything from people who agree with you. Being right isn't enough if you are dead right. I hope our young women readers closely assess the source of liquids that are given to them.
If this happened to me, as stated, I'd go to court right away. This is about the most careless thing I ever heard, giving people diesel fuel in a can marked "gas". I hope they don't sell propane at that station or live ammo with a butt hanging out their mouth.
