2005 F250 SD Tubo Diesel - Gas in Tank

So my wonderful Son decided that while dad was out of town that he would drive my truck, and being the good Son that he is also decided to put fuel back in so I would not be on empty. The problem is that he put Gas back in instead of diesel. He figured it out quicky and only put in a couple gallons and did not turn the key back on, had the truck towed home.

So the question is would I be safe in just draining the tank since the truck was not restarted and the key was not turned back on? I'm guessing it was close to be on empty. Thanks

2 gallons in tank of diesel is nothing. Real truckers used to do it as a anti-gelling protection before other additives become easy available. Just top it off and drive.

I would toss in a few gallons of diesel lubricity additive and forget the problem existed.

Lubricity Additive Study Results - Diesel Place

HE RESULTS:

These results are listed in the order of performance in the HFRR test. The baseline fuel used in every test started at an HFRR score of 636. The score shown is the tested HFRR score of the baseline fuel/additive blend.
Also included is the wear scar improvement provided by the additive as well as other claimed benefits of the additive. Each additive is also categorized as a Multi-purpose additive, Multi-purpose + anti-gel, Lubricity only, non-conventional, or as an additive capable of treating both gasoline and diesel fuel.
As a convenience to the reader there is also information on price per treated tank of diesel fuel (using a 26 gallon tank), and dosage per 26 gallon tank provided as “ounces of additive per 26 gallon tank”.

CONCLUSIONS:

Products 1 through 4 were able to improve the unadditized fuel to an HFRR score of 460 or better. This meets the most strict requirements requested by the Engine Manufacturers Association.
Products 1 through 9 were able to improve the unadditized fuel to an HFRR score of 520 or better, meeting the U.S. diesel fuel requirements for maximum wear scar in a commercially available diesel fuel.
Products 16 through 19 were found to cause the fuel/additive blend to perform worse than the baseline fuel. The cause for this is speculative. This is not unprecedented in HFRR testing and can be caused by alcohol or other components in the additives. Further investigation into the possibilities behind these poor results will investigated.
Any additive testing within +/- 20 microns of the baseline fuel could be considered to have no significant change. The repeatability of this test allows for a +/- 20 micron variability to be considered insignificant.

Thanks for the quick response, sound much better than dropping the tank especially since it's raining today. LOL. Thanks

I would buy 3 or 4 jars of that, toss it all in at once.

It is top rated.



FYI, it is pretty normal for a small amount of water to get into the fuel (even with filtering).

Ditto for bacteria, scum, etc.

All diesel fuel systems are designed to tolerate a bit of crud --- the manufacturers like to scare the daylights out of users about the need for pure / uncontaminated fuel.

But the reality is, the systems take a lot more than advertised.

Just don't abuse it...

If it were mine, I would drain the tank. Do you know for a fact that only a couple gallons were added, or was it more like 4 or 5? As far as lubricity goes, add a quart of ashless 2-stroke oil, I've noticed on a double dose of XPD that my truck starts harder.

This was a pretty common occurrence when I was working in Afghanistan. The military has to use the locals to pump fuel at the POL, so you'd often get petrol in your diesel tank. Go figure.

First 2 gallons in a full tank of diesel won't do any harm. If you put much over 50% gasoline the engine will not run. Contrary to popular myth a diesel engine will not blow up if run on gasoline, it just won't run. Diesel fuel actually has more power (or BTU) per liter and is more flammable.

More BTU yes, more flammable no. You can drop a match in a bucket of diesel, try that with gasoline...

Well if it were my truck, I'd probably want to try to get the gas out of the tank. If I had the right tools, I think I'd try to disconnect a fuel line after the pump and use it to pump out the gas, then replace it with diesel, put in some lubricity agent and go.

But... I don't have a fuel line tool, and the nearest automotive type store is 45 miles away and the truck is my only vehicle right now, so I'd have to bum a ride, etc. I don't have any two stroke oil, but I could probably get some of that at the Merc, which is just down the street. I do have Opti-Lube, because that's what I'm using for an additive.

So most likely, I'd get someone to ferry me to the Merc to see if they had the two stroke oil. If they didn't, I'd do two doses of the Opti-Lube. Then I'd get someone to ferry me to the garage and back with my 5 gallon cans until I got the truck full of diesel. If I thought that their was gasoline in the upper fuel filter bowl, I'd probably try to figure out how to get it out, then do the key on/off thing to purge the air and start it up and run it out.

There is the perfect world, and the real world. In my opinion.

You can drop lighted match into the bucket of gasoline and it will die as well.
Than we do have "stuff" sold in California that is hard to burn mixed with air and using ignition spark. When I drove gasoline car, I always recorded about 15% better mileage on AZ gasoline or other state than CA.
One of the reasons I switched elusively to diesel powered vehicles, even I had to sacrifice my lovely wagon for sedan, since there are no good diesel wagons sold in US for last 15 years.
Coming back to diesel fuel lubricity, lot of experts advise 3% bio-diesel for that. OP might just add couple of gallons of bio to the tank. Suppose it is available in other states, but not in CA.

Thats because it has a flashpoint of 120 deg F. Meaning it doesnt emit vapors until 120 deg and we all no vapors in a flammable or combustable liquid is what fuels the fire, not the liquid itself. Diesel isnt even considered a "flammable" material. Diesels a "combustable" material lol.

Now away from fire science and back on subject haha. My question is cause this has always concerned me. On a 6.0 since the OP and me have that perticular motor, what would you do if you put gas in it and started the truck. Now i know it wont blow the motor, but from a injector stand point, can it harm them??

If you get too much gasoline in the diesel mix, the stability of the fuel mix under compression goes up to the point you will have a no-fire condition. In other words, too much gas = no run.

Now, if there is smaller amounts of gas in the mix, allowing the engine to fire, that could cause some damage in the long run. Gas doesn't have the lube properties of diesel.
