Does anyone have any information concerning the new diesel standards and what they may do to an older engine?   Have heard so many different things not sure if there is anything to worry about or not.

Thanks for the lesson...............

In July I attended the fire safety seminar at the Life on Wheels conference in Idaho. During this course, the instructor indicated that the changes in diesel fuel that the new standards will require, include the addition of solvents to the diesel fuel. He indicated that this may have an adverse affect on the various plastic/rubber hoses, internal and external to the engine, and may, long term, require that they be replaced! I would assume that the same would be true if your rig includes a diesel generator.

I attended a Cummins Engines seminar at the FMCA rally in Charlotte, NC last month.  Here's what I learned about the new emissions standards:

1.  The new Ultra-Low Sulfur Diesel (ULSD) at 15ppm will be available at the pump starting Oct. 15.

2.  The ULSD is backward compatible which means it's ok in older engines.

3.  They expect a 1% loss in energy content which will mean no noticeable performance loss, but potential for "minor" MPG loss.

4.  No change in lubricity performance which means no fuel additives are required.

5.  Engines changing from the old 500 ppm to ULSD could experience fuel system leaks due to rubber/seal shrinkage.  They inidicated that most potential leaks would be around the lift pump and I believe they said they would cover leaks under their warranty.  However, not sure if they will cover if the engine is out of warranty, probably not!

wmalefyt,

Thanks to the info.  I wonder if Cummins will come out with a conversion kit to replace the old seals with new as a kit.  Lets say my warranty ran out... I could go to the dealer and have them install a kit before it becomes a problem.  Did they say anything about doing something like that?

Thanks,

Tom

Tom,

No, I don't recall any mention of conversion kits, but it sure sounds like a great idea!
