Opinions ULSD

[RVTRKN]

Now that most of us are running ULSD, what are your opinions as of now? I have been using Valvaline 2cycle oil 1:140 mix as an additive and can't tell the difference so far. I called Cummins and their take is no additives needed, but just don't trust an $11000. oo motor until it has been proven.

 

[GFreshour]

I just bought an 06, I am worried about anything in any additive. I worry about mexican diesel, dont know about sulphur... ... the new ones will definitely plug up with any additives in my opinion.

 

[MHorne]

i too would like to know more about usld. i have an 05 and either way it looks like i'm going to have to run usld. Are there any side affects of this fuel. and why are diesels being picked on i mean are they cleaner for our enviroment than gas motors anyway?

 

[chuckwilson]

We are all going to be running it with in a year, I have been for last three months, I find Lucus fuel additve works the best.

 

[lethal injection]

Im mixing mine with biodiesel or 2cycle oil when its not avail.

 

[jelag]

I'm going to try this again... seems the last time I hit post quick reply it got dropped...



I've got several trucks and my fuel bill now exceeds $6,000 a month... . I talked with my fuel supplier about 18 months ago about this problem and have started to add back one of the chemicals that do several things... they add fuel lubrication, lower the gel point and add cetane numbers or are cetane improvers... . Lucus, Howes are 2 of the brands we now use... .



I see removing the sulphur as a long term problem and will continue to add back to all my fuel..... and do so in all my trucks... I will not, repeat will not use something that is not recommended by Cummins, or my fuel distributor..... and that includes 2 cycle oil... 2 cycle oil has it place... but not in my engines...



We've been to Mexico and I understand that fuel there is provided by the government Permamex(sp) and over the past couple of years have used 500 or so gallons... with no problems... remember that the same engines we use are sold in Trucks there.....



Well that's my thoughts.....

?????????????????,



Why would you add 2 cycle oil



The CR ISB's were engineered to run the 15PPM stuff, I hope your cat has been removed???.

ULSD hasn't taken over here yet. I can still get good ol #2 with regularity.



Here is my thought... They are saying you will see a 10% reduction in fuel economy with the new and improved ULSD, which begs the questions, if you get less economy which requires more fuel, which dumps more pollutants from the exhaust, did it really help at all? Same argument as driving 55mph vs 70mph - If you drive 500 miles it will take you 9. 1 and 7. 1 hours to reach your destination. Seems that the amount of pollution saved by driving slower is dumped right back out by the amount of time on the road.

I would rather replace my cat than the engine after the warranty is up. Remember its the long term were worried about, so if you go 150K and destroy your engine, EPA is not going care about you. Remember when unleaded became the only gas available and it destroyed the valves in the older engines, EPA did not care. I have thought about and researched this topic for awhile and came to this solution (2 cycle oil) due to the fact that some Cummins engines actually add oil before combustion automatically so I'm told. I wanted to use MMO but was shown it has solvents which would probably make ULSD worse. TX Gooseneck, I bet the tankers are delivering ULSD and not labeling it on the pumps, They are doing this to dilute current stock as used, per the tanker driver I talked too. They only deliver ULSD now and have been for some time, and are not labeled on the pumps. I asked a station owner if the Diesel was ULSD and he didn't even know about ULSD.

I have wondered this same thing, its pretty stupid to make it so our trucks are less effeicient, its either the fuel or the engines, either way we are using more fuel to do the same things. the excess has to be going somewhere. I wouldn't at all be surprised that we are acutally polluting more by the stupid controls put on the fuel and our engines. My '06 does have black soot from the exhaust on the lower quarter panel and bumper. my '02 never did that

I have used Lucas, Marvel and several others but since I dont ahve a good way to really measure the net benefit I am curious as to how people are judging which is best?



There are so many factors that could be impacted like MPG, lubricity, cat problems, engine or injector problems etc etc.



I would like to see some real science behind some testing somwhere to decide which is really the best. But I guess that is an exensive proposition.

I can guaranty that the 15 PPM ULSD will have no long term negative impacts on your CTD, They have tested it and retested it for the last 3 years in our motor research lab.



I will be the ginny pig on this one, I'm not going to use any additives in my 05 I'll let you know.



No flames suits required.

Hasn't ULSD been the only diesel for sale in California for the past 2-3 years? I haven't heard of any ill effects and there has to be a ton of miles driven on the stuff already. Cummins has known for a while that this was coming, certainly long enough to account for the change. In addition, the Bosch fuel system was developed in Europe where the standard has been 50ppm compared to our 500ppm. I think we are OK

This is always an interesting topic to me. I have been running Stanadyne Performance Formula up here since the day I bought the truck. That was 34,000 miles ago. Haven't noted any benefit nor have I noted any detriment. Living here in North dakota it get very cold here in January and February and I buy a 50/50 blend of #1 and #2 diesel. The Stanadyne has kept everything flowing even at 8 hours exposure at 20 below zero. I couldn't plug the truck in she fired right up. Idles a little rough but fired none-the-less. Just me . 02 cents.

Must be that fuzzy TX math giving you trouble again. Time doesn't matter, only the amount of fuel burned.

 

[MEREDOG]

Seems i read a while back that the sulpher has nothing to do with lubricating ?

 

[MegaRocks]

California is all ulsd as of September 1st this year. All states must be ulsd by Jan 1 07' by E. P. A. requirement.



Don't think the ulsd will hurt the common rail engine at all. The 6. 7L engine will not run on anything but ulsd. Today's diesel would plug up the pariculate filter trap in NO time!



Keep addin' your Marvel Mystery Oil and your 2T oil, we'll all see what happens over time!

 

[ILIANBG]

Here in Los Angeles almost every gas station that carries diesel has only the ULSD, and there are stickers on the pumps.

 

[Wayne M.]

Over here we still have 500PPM LSD and I use no additives unless I go on an extended trip. 34K on the clock and no problems (except for a leaky cp3/warranty)



I gotta let everyone here know what has been the norm in NYC. Both the MTA (buses) and the department of sanitation (where I'm a Mechanic) have been using ULSD since at least 2003. They have been paying through the nose for this stuff for the sake of the environment. We have lots of different equipment numbering in the thousands including a few hundred 24V VP44 ISB's used unmercifully in mechanical brooms. There have been no catastrophic or even pattern failures to my knoweldge (and I'm pretty nosy when I see an ISB apart). Everything I see is aging nicely on ULSD. I can see and smell the difference with ULSD. It looks like moonshine or something-very clear, and I am pretty sure the city dosen't spec an additive in the deliveries.

I myself might step up to an additive just to be safe for a little while.

I was talking to one of the Cummins guys at STAR a couple of weeks ago. He said 03 and up, no problems at all. 2002 and earlier 24v should not have any major problems (leaks). 12v 94-98 might have some leaks, and pre 94 will most likely leak. He said they are working on seal kits for the older engines. Apparently the earlier fuel system seals were made of a different material that does not stand up as well with the ULSD.
