Unleaded in Diesel
I saw this post at the SuperDuty forum in Yahoo Groups. What do you guys think?
Subject: Accidentially put 7gal. unleaded in tank.
I drove up to a station with diesel gas and pulled up to the pump with the green handle cover. After pumping 7.2 gallons of gas I relaized I was pumping unleaded fuel in the 2004 F250 deisel truck. Once I relaized it I mixed unleaded with deisel fuel in the tanks. I moved over to the diesel pump and topped off with another 8+ gallons of deisel fuel.
Note: I have about 29gal tank, the tank was half full at the time I pumped the 7 gals. of unleaded fuel in. Has anyone else ever done this? Has anyone ever had an issue since they did? I consulted a buddy who used to run/work with deisel engines and he said they would get a couple calls a day regarding this same issue. Some one else putting in unleaded gas into their tank. He claims that it will not do any harm, may smell a little different when it burns, but recommended adding more deisel fuel when ever possible.
Any comments would be appreciated.

Geez. Bad luck. How far have you driven so far? AFAIK, this is _not_ a good thing. 7 gallons is quite a bit.
There are several problems this may cause. First and foremost, if it was me, I would have the tank pumped and not drive the vehicle. Probably cost you a few hundred $'s.
Gasoline will ruin the lubrication properties of the Diesel fuel and can cause permanent damage to your hp fuel pump and your injectors. Older diesel engines had some tolerance for this, but newer ones are much more pickey about their fuel.
_If_ you've already decided to run it out, I would certainly clear out the local auto parts store stock of diesel additive and dump it in. Get one with lots of lubrication.

i'm a retired dealer tech. so here is what we did. pump out as much of the fuel as you can from the fuel tank.. remove the fuel filter blow out the lines. install a fresh filter and prime if possible. fill the tank with pure fresh diesel. add a bottle of fuel cleaner. and run it. chances are very high to your favor that it will be ok. best of luck.

I posted a synopsis of everyone's answers on the Yahoo site. This is the latest response of the fellow who put the unleaded fuel in his diesel truck:
"I have been driving it over 50 miles a day and after 2 days I topped off with more 7 gals. diesel fuel. I also added some Redline additive for fuel lubrication. A buddy of mine who used to work on diesel engines told me that he does not believe it will be an issue. When he had his business they would get a couple calls a day regarding the same problem someone putting in unleaded in a diesel. I found on another web site that truckers add some unleaded fuel to keep the fuel from gelling up.
So far nothing appears to be different while driving the vehicle performance wise. The exhaust smells a little funny but truck still runs great. "
