Well.. all I can say now.. is that I am a total idiot..
yes any way heres my story
.. I pull up to a Mobil Station here in Irvine CA.. I go to the green pump.. assuming from my past experience that diesel pumps are typically green.. I put my card in.. start pumping away.. decide to fill my SD up.. I haven't done so in a while and it was running on empty.. so I put 17 gallons in.. of what I assume is diesel..add REDLINE then I hop in take off and away I went.. for about 1/2 a mile.. until I hear this severe knocking.. im all hmm.. that's funny.. it was working fine.. so @ a red light I put it in park and rev the engine .. then rev it some more.. still knocking bad.. so I get a green light.. and by this time its running like crap.. so I pull over into a gas station.. which just happened to be next to a Fire department.. so I pull over and get out of my car.. and notice thick white smoke out the back.. knowing something is wrong.. I shut the engine off .. and I just happened to glance at my receipt that I got from the station and it said in big letters REGULAR .. I was about to die.. discovering my mistake.. I figured that I need to get this gas out of my tank..

luckily.. the fire station across the street had a HAZ mat truck out side.. so I swing by and ask them if their is a proper way I can dispose of 17 gallons of unleaded fuel.. and the fireman said that they couldn't dispose of it.. but would gladly take the fuel as a donation.. and dump it intotheir under 2500gallon tanks that they use to fuel their suburbans..
now I only had one problem.. getting the fuel out.. with only a small hand pump and a 5 gallon tank.. and 4 hours later.. I relatively got most of the 17 gallons I put in out of the tank.. I also disconnected the fuel line in the engine bay that leads to the tank and sucked directly from their to ensure I got most of it out.. I then ran the engine .. directly feeding it from a single gallon diesel tank that I store in my trunk.. and it after a couple of seconds it fired and ran fine.. .. I reconnected the fuel lines filled up with deisl and off I was cruzing on the 405 @ 70mph again.. now.. question is did I do any damage? I think I drove a total of a mile.. using regular fuel.. what can go wrong?
is their anything I should do? .. I did add a lot of redline to the tank when I filled it up? and I had run diesel purge about a week before.. ?

Time will tell. You probably are OK..if it's running as before. You might consider having it checked by a competent diesel tech..

Jivesh you are NOT an idiot. It
is clearly a confusing ballot !
There was no expected one to one
correspondence with the green color
and the desired green diesel fuel
candidate....... I'd get a legal
team if I were you!
(sorry I couldn't help it )

Hope your diesel survives.

Thumbs up from me.


It happened to a close friend of mine with his trusty old 240D. He lives 300 miles from me and sold the vehicle before I had a chance to help him do basically what you did. I doubt that you did any damage.

As dingy as I am, I'm shocked that I haven't put gas in any of my diesels.

Good luck,

You should be fine.... mainly since your corrected the problem quickly.

Be thankful it wasn't the other way around. My father did the reverse at a local station. The fuel delivery truck dumped diesel into the premium tank. When dad filled up with premium and drove off, he got about 1/2 mile before the engine gave way. The worst part was, the truck was a new Silverado with a Northstar engine. Needless to say, the gas station bought a new Northstar!

Keep smilin'..... hopefully there was no damage that a filter change won't cure.

In the past 30yrs at dealer I've seen at least 5-10 cars a year with gas instead of Diesel, haven't heard of or seen any engine damage due to this prodcedure. It sure will remove alage from tank. This fuel blend sure doesn't run good in most gas cars either!! Several techs had their gas cars towed in from being CHEAP & trying to reuse gas/diesel blend.
