Question..? What would be the best way to drain the fuel out of the tank? I saw on a previous post that you should put a lubricity additive and replace the fuel filter. New to the site so any help would be greatly appreciated! Thank you!

 

I would pull the filler neck off the top of the tank and siphon it off. There is a ball valve in the filler neck that will keep you from getting a siphon hose in there.

I can get you pictures when I get home if you like.

After you get it out, fill with fresh diesel, change the filter, and some two stroke or power service. Cycle the key a few times, let the pump run, but don't start it. This will dilute the gas.

Did you run it with gas in it? How much gas to diesel?

 

Did you run it? If not, not need to replace the filter. Pump as much out as possible and fill with diesel. FWIW, I'm currently having my injection pump rebuilt, due to a leaking seal. The Bosch tech told me that 2 cycle oil won't do any good for lubricity. If you are paranoid enough about lubricity to feel the need to dump something into your fuel use a product that is made for diesel engines.

 

the bosch tech is stupid!!!!!!!!!!!!!!!!!

 

ill agree the bosch tech dont know diddly

 

Thank you for the info! Yes I drove it from the gas station to the house about a mile. I went to leave a few hours later and it didn't want to start. Just didn't feel right when I backed it out of the driveway. Suddenly I realized what had happened and shut her down immediately.

 

I had about 8gallons of diesel when I filled it up approximately 31 gallons of gas to the 8 gallons of diesel.

Also, can the gas that we take out the truck be reused in another vehicle? Really didn't want to have to waste $80 worth of gas!

 

Lets see, trained Bosch repairman with nearly 30 years of experience or an internet stranger with dubious knowledge and background. I'll go with the tech.

OP, I think you have big trouble. It doesn't matter what kind of snake oil you add to your fuel now, the damage is done. Here is a little info from smeone who knows what he is talking about.

i guess you know the "bosch tech" personally

 

I had a 90's VW diesel. The owners manual stated that you could run up to 90% gasoline to diesel if you were running out and no diesel was available. It said to run the engine at reduced speed, expect lots of knocking and replenish with diesel ASP to increase the centane rating. That injection pump produced far lower pressures than the common rail system in your dodge. However the cylinder pressures are near the same, and a lot fewer moving parts in the common rail that would require lubrication. I would just drain the fuel from the tank, refill with diesel and a quart of Howes Diesel Treat for extra lubrication. Use the water drain to empty the fuel filter and as mentioned above cycle the key to purge the fuel lines of contaminated fuel. Maybe leave the water drain open while key is on to purge lines. Don't put that mixture in any modern gas engines or you will have a bunch of new problems. Don't forget this fuel you're working with is extremely flammable. Good luck. On second thought, also crack all the injector lines after the refuelling process. Then crank the engine at 30 sec intervals [so as not to overheat the starter] until fresh diesel leaks the injector lines. This will stop any more contamination to the high pressure side. I noticed you joined Nov 2010, what day?

 

Please keep the opinions civil, disagree in a mature manner. Please don't make me get involved. Thanks.

What I'm talking about will help out if you have not already damaged the engine. If you've already melted a couple of injectors, it's not going to help you.

I'll stay with my opinion on two stroke, thanks.

I would not try to re-use the fuel in a car, or at least YOUR car

 

Madhat, what is your opinion on 2 stroke oil?

 

That it acts as a lubricant in the fuel and increases the BTU content of the fuel. Granted, not enough to offset the cost of adding it vs power/mpg gains... in this specific case, I would be using it to offset the drying properties in the gas.

That being said, too much of a good thing is bad. Cummins recommends no more than 10% WMO in the fuel mixture, I don't run any more than two quarts at the most per full tank. (that was when I was running JP5). I'll only run a quart every couple of fill ups now that I'm running regular diesel, I'll alternate between that and some power service.

From what I have read, the newer trucks have not had a problem thus far with the ULSD, so there is no real reason (allegedly) to put additives in the fuel for the purpose of lubrication. It's not gonna hurt, tho.


Let the flaming begin.

 

Will the gas and diesel separate if let to sit after a while, like salad dressing?

If so you may be able to siphon the gas off the diesel after you get it drained out of your tank. 39 gallons is a lot to separate.

 

i don't think it will separate since both are petroleum based...sort of like putting 2 stroke oil in your fuel .....it mixes well
