Fuel Question

redneckmexican · 02-06-2007, 06:57 PM

I just recently bought an 06 dodge 2500 4x4 and i was thinking about a trip to mexico. i researched the fuel and they are still running 500 ppm sulfur diesel.. would that be okay to run in this truck.. planning on keeping plenty of fuel supplement on hand for it, but should i be leary of running it around in mexico? thanks for any help..

Probably run better and also get better mileage

the 500 ppm sulfur is that low sulfur? or is low sulfur diesel less ppm?

From wikipedia:
The allowable sulfur content for ULSD (15 ppm) is much lower than the previous U.S. standard for Low Sulfur Diesel (LSD, 500 ppm), which not only reduces emissions of sulfur compounds (blamed for acid rain), but also allows advanced emission control systems to be fitted that would otherwise be poisoned by these compounds. These systems can greatly reduce emissions of oxides of nitrogen and particulates.
...
Sulfur is not a lubricant, however the process used to reduce the Sulfur also reduces the fuel's lubricating properties. Lubricity is a measure of the fuel's ability to lubricate and protect the various parts of the engine's fuel injection system from wear. The processing required to reduce sulfur to 15 ppm also removes naturally-occurring lubricity agents in diesel fuel. To manage this change the American Society for Testing and Materials (ASTM) adopted the lubricity specification defined in ASTM D975 for all diesel fuels and this standard went into effect January 1, 2005. [3]

There may also be a minor decrease in the energy content, by about 1%. This decrease in energy content may result in reduced fuel economy. To achieve the sulfur requirements for the new fuel standards, diesel manufacturers include an additive to keep the fuel flowing smoothly, and to prevent engine damage. A relatively cheap lubricious additive is biodiesel.

So in my old dodge doesnt like the new fuel. I get alot less smoke(boo hiss) and about .5 mpg less. But it also could be the winter fuel... anywho there ya go.

Thanks alot and off to mexico i go then.. lets just hope it dont get stolen!!!!

so just going to hi-jack this thread for a similar question. I am looking at buying a first gen Super Duty PSD in the next few months (more likely 6 months but whos count besides me right?). Anyways, I have just started researching Diesels more...so please flame 'lightly'.

A guy who is all 'pro-gasser' and anti anything diesel, told me that with all this new ULSD fuel going into affect the older generation diesels will have issues with the new fuel. Things like leaky fuel system components, bad milage, etc. This has me a bit concerned but seeing that he's anti-diesel I figured he's just trying to convince me to buy a gasser instead. None-the-less, if I go with a first gen Super Duty will what the guy said be true? I'd assume not because I have yet to hear any out-cries from anyone, but thought I would atleast ask.
Thanks,

well im not sure im new to the diesel world too but i heard they are supposed to put extra lube to compensate for the lack of it.. but just incase i still put a bottle of diesel fuel supplement every other tank just in case.

Yes we do. The new engines are desgined for the ulsd. not our older engines. We use the feul to lubricate the pumps among other things. Then new enigines are desgined diffrently. I dont remember the specifics right now as I am too tired.

One sugestion to you is not buy a PSD. Goto a deisel shop and ask them about the reliability and the problems they have. Then ask them about a cummins engine and thier opinion on them. THen go look what they are driving. Havent found a shop yet who likes/drives a PSD. I bet they are out there though.. My .2

I have to agree about the Cummins. If you want to know what is effected by the ULSD in a PSD, go check some of their forums. I know the first gen Cummins are having some problems with seals in the injection pumps because of the lesser amount of sulfur. Other than seal issues and maybe a small loss of mileage, you shouldn't have any issues with the new diesel. But as others have said, a good additive is always smart to run regardless.
