Engine/Transmission (1998.5 - 2002) New diesel fuel

[RRuggles]

Just read an article about the new low emission diesel engines and the required fuel. Will the fuel have any detrimental effect on the older engines? If so, what to do about it?

 

[bbodammer]

The problem is that more restrictions keep getting put on our fuel and engines. They are losing a lot of the lubricity in the fuel because of it. I was told that the fuel keeps getting dryer and therefor much harder on the the older trucks and the VP44. I continue to run standanyne in every tank and have even upped the dose to help lubricate the pump. I'm also reading lots of info on Biodiesel to see what the benefits are. I'm sure others will chime in with their thoughts as well

All the more reason to run bio whether B100 or a mix. I read an about the lubricity of the fuel and they have no clue how the seals, o-rings or gaskets in the fuel system will hold up. Also if you have an 07 diesel it will require the new ULSD fuel and you are not supposed to run anything else. Say for example you find some of the old diesel you can't run it. The fuel pumps will have stickers on them telling you that the diesel is the new ULSD 15ppm, that is required.



Some service stations may even be required to have their tanks pumped dry and cleaned before they can sell the new stuff. The new stuff may be in short supply as refineries change over. Don't look too good for our wallets. Diesel here is around $2. 50 and up, I got B100 for $2. 45 last Friday.

Bring on the BIO!!

Even blends as low as 2% will hugely help lubricity and such.

Why can't we get ULSD with some BIo blended in to make it better for the pumps and such?

I can't see how a mere 2% or 5% bio would totally ruin the cold weather or mpg qualities, and it certainly helps lubricity.

What will these new fuels do to our fuel economy? Will the cost of fuel be higher?

 

[SHobbs]

From what I have read economy will suffer a bit and the price is due to increase.

it's dryer, but there's a new additive.



The 07 trucks will have a sort of cat that will clog up with the old fuel.



there's a big writeup in this month's petersen's 4x4 and offroad. It's on newstands now.

Cummins has an "early warning" posted/dated 08/05. "Lift Pump Leakage due to ULSD".

Read it and weep.

I have seen first hand the affects of the ULSD at my work place. We have been using ULSD since Sept 04. Just a couple of days ago I lost the fuel pump (lift pump) on my 2003 yr model Volvo motorgrader weather it was the fuel or just the life of the pump who knows for sure, it only had a little over 1700 hrs on the grader. The problems we seen the most was with the older fleet yr models of our crew pick-ups, the latter 90's and early 2000 yr models when the fuel was first introduced to us, the newer vehicles did not seem to be affected by the fuel. It was lift pumps leaking internally with only fix was to replace with new one. This problem of a drier fuel seemed to be fixed with the benefit of adding a diesel fuel additive to our storage tanks. Not long after additive was put in problem leaks ceased to exist. No injector pumps were replaced to my knowledge, I usually check with our shop mechanics every so often and ask if any more problems has come up since the fuel additive was introduced, there reply was none so far. As far as mileage goes with the ULSD I could not tell you, there are four of us that occupy the 04 Ford crew-cab and it see's a lot of idling plus the other three occupants do not own diesels and could care less.



I have recently started using B20 bio diesel in my 03 and have found my truck to really run smoother and sounds quieter with no mileage loss, in my opinion it seems that the mileage has increased slightly JMO.

From all the info I have been given, the oil companies all but guarantee the lubricity of the fuel. I have heard statements made that they are using better products to provide lubrication than we can purchase. we'll see. I have my spare vp and lps on the shelf.

 

[59Turbo]

What about adding one or two quarts of new or used motor oil to the tank? Would that increase the lubricity enough?

 

[dpuckett]

From my reading, motor oil, ATF, et al, dont add the right kind of lubricity to the fuel, they just make it thicker. Not sure exactly how it wroks, but I'll keep the motor oil in the engine, ATF in the transmission.

The heck with 1-2 qts how about 25-35% of total fuel in tank. thats what i do. the heck with oil companys and the epa. mix it up and burn it up.



Have had not one problem mixing yet. cross my fingers.
