Engine/Transmission (1998.5 - 2002) Recommended Fuel Additive

[krtcummins]

From what the oil companies state, the reason the ULS diesel lost lubrication, is the process that they use to remove the sulfur. Apparently it's some kind of a heat process used during the removal of the sulfur. What I want to know is what is being removed from the fuel that is the lubricant? Oil?

Belief in diesel fuel additives is a religion based on faith. You simply have to choose to believe and ignore all criticism, all opposing points of view, the truck owner's manual. printed recommendations published by the engine manufacturer, anecdotal evidence offered by others, and facts.



Have any of you who practice this religion ever noticed that commercial truck fleets, company fleets who own as many as 100, even 200 trucks, trucks costing $120k or more, all of them fueling every single day and running more than 100k miles each and every year, trucks with 500k mile engine warranties, and all of them required to provide at least 500k miles of reliable service to the initial owner, don't use any fuel additives? Ever wonder why?

I can tell you another reason LARGE trucking companies dont use a lube in fuel your rite. The reason is cost and having to lug around a bunch of additive. Think about the way big truckin companies do business. Most lease their equipment and really dont care. In 300k their going to S can the truck and get another with warranty. So they dont have to have a string of mechanics with $10K tool boxes and that will cut overhead because a parts changer doesn't cost as much. They really dont have to do much but change oil and filters and put some new sneakers on it once in awhile. Thats why Freightliner is so big they sell the V W of big trucks cheap because they are. And buy the time the warranty is up the driver has tore the crap out of the POS anyway so they sell it to Mexico because they have no emmisions laws down there. And the company sticks the driver in a new VW freightliner POS he's happy (we are easy to please) and the cycle starts all over. So if you intend to treat your Dodge that way then thats the way to do it. It must work look at JB Hunt Mega Millions every year. How? read above and that's how. But someone that takes pride in his ride will take care of it. OO's that have been at it awhile dont have a Freightliner POS they have something that will last. When the last time you looked at a show truck that is a Freightliner (that didnt have dingle balls and a fuzzy toilet seat dashboard cover)single truck OO's spend money wisely and take care of what they have and ALOT use additives in their fuel

The process to further refine out the sulphur dropped the lubricity becuase of the loss of the the large long chain molecules that contain the sulphur. These large molecule composites were what provided the lubricity.



The molecules are also relatively volatile and essy to break down so during the combustion process the sulphur was released into the exhaust stream. IIRC, cetane and BTU's also dropped because of the loss of these components. It really was triple whammy to remove the sulphur to meet emissions.

Ive been using stanadyne, not just because of lubricity, but I do get a small increase in power that I can really notice.



Here in Washington State, they mandate 5% bio diesel. Is the bio by itself a good lubricant ? Or is an additive still necessary for lubricity ?

 

[BIGNASTY]

It makes sense for VE and CR's also, or anything thats internally lubed. The removal of sulphur has had the side effect of removing the large long chain molecules and aromatics that provided the lubricating properties in the older diesel.



As fas as big runs running with no issues, doesn't happen. Bad fuel, fuel gelling, etc, happens as does issues with injectors, pumps, etc.



The assumption that big rig fleets don't use additives and run trouble free is naive at best. Quite a few drivers that own or lease their rigs use additives religiously. A lot of companies that own trucks also spec an additive that the drivers are supposed to use when fueling.



Take a look at the selection of the additives available at truck stops. Stocking that much would not be fiscally feasible if they didn't have a huge turnover. Its not unusual to see 1 out of 4 fuel customers walk out with a bottle of additive and its a good bet 2 out of that 4 already has some in their truck.



What is pulbished, not published, reccommended, not reccommended is not even a consideration. That myth has been adequately disproved enough times for most people. Just because Cummins and\or Dodge doesn't take out full page adds and plaster it on billboards doesn't mean its not a good idea or not needed. :-laf

I guess I should have read the posts before I wrote the last one I did I wouldn't have had to type it thanks Cerberusiam thanks allot :-laf

With all the good stuff removed from the new diesel fuel, one might as well buy a gas motor. Costs less to start with and now days gets about the same MPG. I hear the new Dodge trucks average around 14 to 15 MPG. Not like our old second generation trucks that got 21 on the road! I think my truck was around $4000. 00 or so more for the diesel package. I hear it's closer to $6,000. 00 now. Except for power, a new Dodge with a diesel might not pencil out like it used to.

Tow something with GAS and you wont say something like Gas Dodge trucks again

 

[krtcummins]

But if you don't tow,,,,.

But if you don't tow,,,,.

Then buy a Chevy I think they are built better than Dodge.

I thought the Duramax was a good engine?

Drive that gasser around like you drive your diesel and you will see just bad it can get. Heaven forbid you EVER tow more than 6k and those single digit, LOW single digit, mpg numbers take all the fun out of a trip. Not to mention NOTHING will pull with an inline 6 diesel.



For a DD buy a VW TDI or a 4 cylinder gasser and save the truck. I have yet to see a gas engine in a full size truck compete with a diesel for mpg given all things are relatively equal. About the only time you can get close is very low speeds and driving like your scared, then, abiout 60k get rid of it cuz its on the short side of costing you money.

I agree completely with that!

It's not bad now as V8 engines go but it is not and never will be a Cummins.

V8 diesels do NOT develop high torque at idle or max torque at 1500 rpm like the Cummins inline six cylinder and have a service life of approximately 50% of the service life of a Cummins.

V8 diesels are great for fast acceleration but have to be wound to higher rpm than our Cummins to produce torque required to pull a grade. Higher rpm means accelerated wear and reduced fuel economy.

Colorful advertising sounds great but it cannot overcome the laws of physics.

Jetspeed Inc | Flickr - Photo Sharing! These are the OO's that dont mind using ADDITIVE just a little better ride than your basic FLEET TRUCK. They have a few of these trucks that run JET fuel everyday in So Cal. The lens on their marker lights are glass and cost more than most fleet truck engines.

 

[BIGNASTY]

Another bunch that run everyday out of So Cal Banning I dont know but I think JUST A LITTLE BETTER THAN JB hunt or fleet trucks?YouTube - ‪Green Thumb Produce's Red Peterbilt‬‏ and I konw that they run additives for no reason none at allhttp://www.youtube.com/watch?v=U-ClzgZCgsg And these CAT MOTORS DONT WANT TO BE A CUMMINS

 

[BIGNASTY]

These are the truck of my child hood in trucking I dont think this guy will pass the snap test do you YouTube - ‪1969 PeterBilt Truck 900+ HP‬‏ A week's worth of fuel for the Dodge just went out his stacks

Green Thumb Produce has a great deli inside of their store. An Italian family owns it. Great food and great produce. :-laf

When I was in So Cal working I use to stop in and talk to the guys. And have something to eat. They are great people and the trucking Industry should be proud to have them.
