Yeah, I goofed. Grabbed a jug and dumped about 4 gallons of diesel in a gas engine tractor. I dumped another 9 gallons of gas in hoping that it would dilute it enough to run. No luck. Is it possible to do that or is it time to drain and start over? It is a John Deere 400 industrial.

Back years ago I would run a bit of diesel in my Dodge van as as a upper cylinder lube. But yes you need to get the gas to diesel mix to something like 1gal diesel to 20 of gas

I think I would siphon as much out as you can and start over.

you are way over the limit. u could get away with 10 percent . at close to 50 percent it will not run. and with excess diesel all you will do is dilute the oil with the unburned diesel going past the rings and you could glaze the cylinders if its not running hot enough. , then it will burn oil. too much of a good thing is no good. just get an electric tidy tank pump and pump it out.

The diesel and gas will somewhat separate out in the tank. Diesel will go to the bottom. I'd try to siphon out about 4 gallons from the bottom. And then see what happens. See if it will run then. But if you have already tried to make it run, which it sounds like you did, you'll need to drain the carb and fuel lines and filters. And get the straight diesel out of the lines and carb. You'll probably have to do that no matter what you do.
If that don't cut it, then you'll have to drain the whole tank, along with the carb, lines, and filters.
If you don't believe me about the diesel separating from the gas, dump a little of each in a glass jar (about half and half), and see for yourself.
Your fuel supply comes from the bottom of the tank. So you are essentially trying to burn straight diesel. Dumping 4 gallons in, is enough for it to be pulling nothing but diesel off the bottom of the tank.

I worked in a shop that worked on lawn mowers. About once a summer this guy would put diesel in his rider mower, well we would go and pick it up and bring it to the shop. I would take the gas/diesel home and use a little at a time in my rider. Then one day my walk behind mower ran out of gas and I was so close to being done. I dumped the gas/diesel in the mower and finished mowing. Then the next time I used the mower and it would not start. It took me a minute to figure out what happened, when the engine was hot it would run, but when cold no way.

I don't know if it will separate or not never bothered with mixing and letting set to see. I would just drain off the tank then add more gas to the mix as time went on and use it up. Or you could use some of it in your diesel tractors tank this winter for the antigell that gets beat to death about every 2 weeks on here. We had a gas supply issue 50 years ago, with the local supplier either not filling, or over filling when he was here, so we ran short of gas during spring planting one year. Mom would get 15-20 gallon of gas at the station and I would pour in about 5 gallon of diesel fuel and tractor ran fine on that plowing. would fill then go plow or disc it out then have to refill again did that for a weekend never bothered the tractor and never went to burning oil either just ran a wee bit hotter on the temperature gage on a hot day. This was on an 830 Case. Straight gear transmission.

My neighbor's son filled their diesel Golf with gas. Son estimated it was about 50/50 blend in the tank.
Neighbor drained/purged it all out and got it running again.
He asked if I could use the mix so I took it - three 5 gal pails.
I mixed it 50/50 with new gas and used it all up bush hogging in a Ford 4000 gasser.
It ran fine. Under heavy load the exhaust would blow a whiteish gray.

Probably be about what used to be called Tractor fuel.I'd dump in a can of Seafoam and run it.If hard to start give it a sniff of starting fluid.

I used to run about 10% diesel in our Farmall C, with E-10 gas, and it started and ran just fine, maybe just a little smoke when starting it cold. I did this thinking it would reduce the possibility of corrosion in the gas tank. But then I noticed that the engine oil level rising, and it wasn't hydraulic oil. I think this was common back in the days of running distillate, and that's why Farmalls have the 2 petcocks on the pan, to drain excess oil and refill with new.
