Whatcha think?

06 with 7,500 miles, Monday I drove the truck 125 miles, it sat for about two hours, went and started truck to return home, bad miss, shaking, blue smoke. Shut it off, restarted, same thing, revved the engine slightly and it leveled out. Drove the 125 miles home without incident. Tuesday morning I started the truck, we're back the the shaking/smoke, revved, restarted several times, no improvement. Called dealer, they picked up truck (on a tilt bed wrecker, I sure hated to see that). Dealer called me yesterday to pick up truck which I did today. The service writer said when they unloaded the truck from the wrecker it was running terrible, they restarted a couple of times and it cleared up, they drove it several miles, all seems ok. The service writer said one of the first things they did was run a fuel sample, said my fuel was just about the cleanest he had ever seen, (I run all my fuel from my aux. tank through a filter before it goes into the main tank) also said 98% of trouble they see with injectors is trash in fuel. I asked him if there was anyting I needed to do to help prevent future problems with the injectors, he said to add one of those small containers of two cycle oil to the fuel tank about every third fill up. I drove the truck home from dealer which is about 65 miles, ran good. I know the "adding two cycle oil to the fuel" has been cussed and discussed here. Just thought some might be interested. bg

98% of the trouble with injectors is because of trash in the fuel... . humm, thats because DC wont use a 2mic fuel filter like Cummins suggest, their fuel pumps cant handle it! So then they come up with a whole line of BS regarding the problem.

My next question would have been, "Where in the Owner's Manual does it suggest I add 2-cycle oil to the fuel?"



The same question I asked a Cummins Southern Plains tech years ago when he advised adding ATF to the fuel in my previously owned '97 CTD. I didn't do it then and wouldn't add the 2-cycle oil now either.

If you want to stick to what Cummins says use the Valvoline/Cummins injector cleaner. Though I think any high quality product (made for diesels) would suffice.



It's funny that they recommend 2-stroke oil since even Mopar has a diesel additive. You might have had a sour tank of fuel but I doubt, it I wouldn't think you would get intermittant problems, I would figure the problem would last for the whole tank of fuel.



The one bad tank I got had a low rpm miss for the whole tank, I never got any water out of the filter housing and it didn't trash the filter but the very next tank of fuel and the problem was gone.



Yes DCX is too cheap to put a suitable lift pump/filtration system on these trucks. It borders on criminal and sooner or later it will bite them on hiney. I myself will NEVER buy a brand new Dodge again.
