Haven't had any problems until now. 17,000 miles on the truck. OEM fuel filter (new dual pleat) has 7,734 miles on it. Nicktane Cat fuel filter has 6,225 miles on it.

Filled up this morning. Drove about 1 hour to work. About half way noticed the very minor fuel knock I always thought I had was a little louder. Didn't think much of it.

Started the truck at lunch because I had to go back home and noticed it cranked just a little bit longer than normal. Noticed this because there is normally very little crank and it starts right up. Didn't think much of it.

About halfway home I have a brief period of stumbling / surging followed by some loss of power and noticably louder knocking. Continues with less power and the louder knocking the rest of the way home. Now I'm worried.

Got home and hooked up the Innova scanner and found no codes.

Added 16oz. of power service and got in to take it around the block. Turned the key and it cranked about 5 secs. and displayed 'SERVICE 4WD' on the DIC with no start to I turned off the key and waited a couple seconds. Turned the key again and it started after a little cranking, no message. Took it around the block and got on it hard. It sounded o.k. and power seemed o.k. but it still sounded like it was knocking. Checked fore codes again and nothing.

Took the wife's car back to work. Will check it out more when I get home.

I'm thinking it was bad fuel but the station I filled up at is only a couple months old. I'm hoping the power service will help. I will check the OEM filter for water when I get back. Anyone have any ideas? I'm stock except the finger stick, egr block and MBRP 4" turbo back.

Injectors??

Sucking air at your new filter connections???

There is no smoking and there was no smoking when I had the stumbles so I'm not sure its the injectors. Wish I had a predator so I chould check the injector balance rates.

I thought about injectors right away but the harder starting / power loss is making me think maybe water in the fuel but I didn't get a wif message on the dic.

I'll run it this weekend to see how it runs and take it to the dealer on Monday if there are still problems. I'm hoping its bad fuel and will clear up when I run out this tank.

I thought about air too but I've run the Nicktane for 3 months now with no problems. I gues its possible something could be working its way loose.

There is plenty of guys in your area that could loan ya a programmer to check injector balance rates.....does Mcrat live close to you....pm him and he might be able to hook you up.

Mark give me a call. Sounds like you might have a cracked block or broken piston. But seriously, maybe an injector has waited to show its ugly face until now. I have a predator you can use for a while so that if the knock is intermittent you can check the balance rates when its acting up.

I would try priming the new dual pleated filter. they have been finding some with pinholes in the bottom causing them to lose prome slowly. it sounds more like air to me. it also sounds like you need to check the injector balances as well.

Sounds like it could be bad fuel, you said you filled up in the morning.

The same thing happened to me and fortunately i had amsoil/dahl fuel filter water separator and had to drain water from the separator every 50 miles. Truck never had fuel knock before and during the bad fuel sounded like an old dodge. My filter is 2 micron and changed it and stock filter after next fillup and never had problem again. I would run it as close to empty, then change filter. hope this is all it is for you. there is alot of crap being sold as diesel and they are proud of the stuff to boot.

Thanks for all the suggestions. I started it up and took it aroung the block on Saturday morning and it ran o.k. It was still knocking but it ran o.k. Went out to run errands and it ran o.k. except for the knock.

Well, I finished my errands and was ready to leave an - crank no start. Called Clyde (Socaldieseltech) to ask what he thought and he said to pump at the filter and start. I pumped and started a few times and it would run then quit. I opened the bleed screw and bled some off then pumped some more and it started. Glad I kept trying. I was about to give up an tried teh last time and it worked.

Knocked pretty bad on the way home. Started up fine a couple times today and I can hear a little knock while idline. Didn't drive ti today. Taking it in to the dealer on Monday. Have to go for some other stuff anyway. We'll see what it is. I think it may be an injector. I think the fill up may be a coincidence but the losing prime is confusing.

Clyde - thanks for offering the predator and helping me out on the phone. Maybe I'll be buying the Predator sooner rather than later!

Problem found - knock explained. Took it to the dealer. Was losing prime because of a leak in the oem filter assembly. When the took off the filter they smelled gas. Well, I had filled it up on Friday night and I damned sure didn't put gas in. Went to the receipt and sure enough it says diesel. Put in 21 gallons. There was gas in the diesel tank at the station.

Called the station and, suprise, other people called. But get this - the people that called had filled up with premium and had gotten premium with diesel in it! I was the first to call about gas in diesel.

The station is a recently built Shell station just off the 15 on Ontario Ave. in Corona. If you went the on Friday you may have gotten gas too.

Mine is in the stealer for the similar problem. Filled up from near empty and after 10 miles it ran rough and eventually died and would not start. I might get some info on Monday. Mine is at Nabers in Costa Mesa

As I understand, the gas going into a diesel is not as big a deal as diesel going into a 'gasser'.

Lets hope the big name 'Shell' stands by their name and buys you a whole new fuel system for starters -- ala injectors, pump, drained/cleaned fuel tank, etc.......http://www.dieselplace.com/forum/images/smilies/grd.gif

I would definitely consult with a pro from GM [district CSR or higher] and or a 'Deceptive Business Practices' attorney.

Speaking of attorneys, if they threaten to not do a http://www.dieselplace.com/forum/images/smilies/censored.gif thing, then I would THEN contact your state Attorn. Gen. as well as the media for starters.

People tend to change their positions when the ole media shows up on their doorstep [TRUST ME]http://www.dieselplace.com/forum/images/smilies/rockon.gif

I sincerely hope this has a happy ending.

I would like to start by saying that this was proabably an honest mistake and doing what has been mentioned here is very extreme. I would feel comfortable that whoever is responsible for the error will take care of it as necessary and recomended by the manufacturer.

There may be some out there who remember about 10 years ago Chevron had an issue with the flashpoint of the fuel which was too low and caused a very hard starting issue. This error effected most of the west coast. Chevron, once it determined the error did what was necessary to correct the problem, WITHOUT ATTORNEYS, WITHOUT ANY OF THE OTHER THINGS MENTIONED HERE.

What some do not know is that at the very same time, somehow at a warbirds airshow, JP5 got substuted in place of AvGas. This also only affected the aircraft which fueled up at that airshow. Fortunatly no aircraft made it into that air, but several P-51's and a couple od DC-8's burned up their engines on the runway while taxiing. Chevron wrote each plane owner a blank check for repairs of those planes.

I hate shell, but I am sure that the company will take care of this readily, Just give them a chance. OK

Hello.

With all due respect, I believe you are right. They will repair it.
Shell is a HUGE NAME.

There are some caveats to this problem though. AKA -- If they are Private Owned vs. Corp. owned. They MAY not want to file a claim if it is private. BUT, it will be in their best interest if they do.

Also, take a look at my composition. It is an 'if-then' structure.
If the liable station chooses not to fix it, THEN........

I hope you understand?

It happened to me sir. [Different Station]

Long story short, the Corp. SUED the PRIVATE owner.

And you better believe that I did everything mentioned in my post to FINALLY get it settled.

Why? Because the SOB didn't want to admit Censored

'nuff said.

Just another thought for you here, you may not be dealing directly with either the station you got the fuel at, or shell. I say this because the cause of the mixed fuel was probably due to an error by the delivery tanker driver. But I suppose it could have been a mistake at the terminal where the fuel was loaded into the tanker by a loader, or even a improper pipeline delivery to the terminal. :confused:

I know...so may choices, but again I am sure shell will stand behind thier product and work out who is really going to pay between themselves. ):h

Do you know if this problem affected only this one station, or did it affect every station in yourt area??

John

This is the only Shell in the area so I am not sure if others had the same problem but, according to Shell Corporate, it was the tanker driver that caused the problem. He pumped diesel into the premium tank at the station and premium into the diesel tank. Bad day for me but a much worse day for the gassers.

Well, Shell is paying up but they screwed this up too...in my favor!

They said they needed 2 estimates. I gave them the work order from the Chevy dealer and another estimate I got. Chevy charged me $364, plus the $56.78 for the fuel that comes to $420.78. The other estimate I got was $516.72.

On teh stuff I sent them I clearly said they needed to pay me $420.78. They are paying me $516.72! They screwed up and paid me from the higher estimate!

You sure they screwed up? I'll bet they did that on purpose..........

I tend to doubt is was on purpose. I can't see them being willing to pay anymore than they have to. Based on the feedback I got from the people on the 800 number this sounded like it was a fairly common thing. I'm not sure they would like to be blowing that much money. If they did do it on purpose, great, but I'm sure not going to ask. If they did pay extra on purpose this will be the first time I've ever gotten anything other than an 'oh well' for any customer service screw up anywhere...
