Well, I did the unthinkable, while unthinking. Maybe it was a senior moment. Anyway, VERY LATE last Thursday night on my way home with an empty tank I stopped to fill up my diesel tank. Went inside to pay, then back to the pump and filled my tank with RUG (regular unleaded gas).

It drove home fine (only 1/2 mile), but Friday Morning when I tried to start it, it ran VERY rough and would die if I shifted into gear. I used another car for the day and looked at it Sat, with same results. Finally Sunday morning I had this horrable thought that maybe I got the wrong fuel, so I found the receipt and sure enough, it was RUG (just so you don't think I am completely incompetent and unworthy of owning a MBZ diesel (1985 300SD), I just bought this about 1.5 months ago and it is my first diesel vehicle, and this is my 4th tank of fuel - 3 out of 4 is not that bad in baseball, actually I am batting 750, lol).

Back to my problem - I'm thinking that I should syphon out as much as possible from the return hose under the hood, then try to add diesel through the supply line (both have hose clamp). I hope 5 gal is enough diesel to add to get it running so I can go back to the gas station to fill-up again - this time with #2 diesel.

Any comments or suggestions would be appreciated. Please remember that I already have a wife that is more than willing to point out the error of my ways, so any jokes, putdowns, etc. are ok, just add something positive also. She was not able to do the latter.

Thanks to all, and I hope all the rest of you that have done this will learn from my lesson, even tho you were not brave enough to post and ask for help. Actually, tho, some of you may have, but I did not find your thread when I tried to search.
