I recently got a very bad batch of diesel at a local Conoco station.


The sample looks like there is oil in the bottom of the fuel [lots] And, I have the receipt to prove how much, and when i got it, etc., etc. The problem surfaced [water in fuel] light that came on on the DIC about 12 miles from fillup.


The owner is categorically denying the whole thing.


Dealer said to get it 'back in warranty' they must replace the fuel pump, injectors, filter, purge the lines, drain/clean the tank,etc.........


In other words, by no means is this a small repair bill $$$$$$$$$


First off, does this sound legit? And second of all, without having to go thru all the expensive legal proceedings to get this mutha to claim it on his insur., what would you recommend I do to fix the fuel related problems........?

change the filter, drop the tank and clean. Then persue the owner of the station, get a laywer involved if needed. Its his fuel and he is responsible for its cleanliness. If only a water in fuell light on, change the filter every tank and run some good additive to get rid of the garbage as much as you can..

Go back to station and take a fuel sample from the pump. May help in proving where it came from.

That stuff that your referring to thats on the bottom and looks like oil, is actually dirty rusty stagnated water, by any chance did you notice if the Conoco where you fueled up at had a delivery tanker parked there that just made a fuel delivery, if so that would explain where you got a load of this in your tank, I learned this from my old man who was an owner operator, he told me to never fuel up at a station where you just viewed a tanker dropping a load of diesel in the underground tanks, what happens is the underground tanks sweat inside as the fuel level drops, this condensation collects on the bottom, at times there may be gallons of this gunk laying on the bottom of these under ground tanks, but because fuel oil (Diesel) is lighter then water the oil always stays on top, thats why the draw pipe is cut off about 2 1/2 feet from the bottom in these under ground tanks so as to avoid someone sucking this crud into their fuel tanks, but that doesn't work when they get a fuel delivery, because when they dump the fuel in it stirs the gunk on the bottom up, then someone like yourself comes along and pumps a load of it into your tank, as far as making Conoco pay for it, your going to have a ruff battle, you might be able to get your attorney to get a hold of the fuel delivery records who's times match the time on your receipt and see if any delivery's were being made while you were there fueling up, what you need to do now is do what dmaxalliTech suggested, drain the tank and put new filters on, then dump some good clean fuel in along with a good fuel treatment that will disperse water and clean the injector's, then drive it till your down to 1/4 of your tank, then fuel back up and add some more good fuel treatment and replace the filters again, you may need to do this 3 times before your tank and system purges all the gunk out of it, one other thing do yourself a favor and add a secondary fuel filtering system on your truck, I haven't even received my truck yet and I have my new kit setting on the shelf ready to install as soon as I get it home from the dealer, if you need one dmaxalliTech sells them, PM him and he will fix you up, its the best investment you can make if you own one of these Duramax equipped trucks.

Ok, but in relation to my previous question, is the fuel related components warranty voided because of a very bad batch of fuel?

Actually no. I got some of the last of the tank. I went the next day for a sample to confirm that it was his, and could only muster about $.45 worth from the same pump before it stopped because of no more fuel.


Owner acknowledged that he was out of fuel.


As I stated, I showed him the bad sample taken the next day, and he basically called me a liar. I have all the receipts to prove it too.


Oh yes, I did save the samples.


In regards, to my post, is GM correct in saying that my fuel related component warranty is voided because I got very bad fuel?

first of all, its unlikely you need all them parts.


And as for the owner, he is out of fuel and that just leads more to the arguement of chitty fuel...bottom scraping
