Has anyone considered adding 2 cycle oil to their tanks to prevent damage to injectors and related parts as a result of ulsd?

 

Why?

What leads you to believe that ULSD will damage injectors and related parts?

 

NOT good to do.......

 

ford already has a lubricity additive, ask your dealership

 

I was just reading another forum in which the posters were concerned with lower lubricity of ulsd. (particularly with the high pressure pumps for common rail injection) some were using it as preventativ maintenance. We dont have the same pumps but I was just curious about their claim of increased mileage and lower noise levels. Maybe lower noise, but better mileage? doesnt seem likely.

 

thought about using bio diesel and supporting americas farmers?

 

How much per gallon, and where can I get it?

 

Use a fuel additive…….that will also work.

Ultra Low Sulfur Fuel does not mean low lubricity.... it means low sulfur.

All diesel fuel should meet a minimum ASTM rating/certification that meets the automobile manufactures needa and EPA's requirements.

Many use additives as a preventative measure and like the piece of mind that if the fuel they do buy is slightly off, then hopefully the additive makes up for it. No additives will make bad fuel good, but it will add in a cushion of margin that many like (myself included).

Some of the additves out there add only injector cleaners... and nothing more.

Some add lubricity and cleaners... and nothing more.

Some add lubricity, cleaners and cetane booters... and nothing more.

Some add lubricity, cleaners, cetane boosters and anti-gels for the winter.

Use the brand of your choice and the appropiate additive for what you want to add or gain. There are many out there and you will not get a 100% clear answer on what to use... so please do not ask... just use one that has no alcohol and is designed for diesels!!!

May I suggest a local truck stop as they carry a few brands that work well.

 

Yes but sulfur is a major lubricant in the fuel system. Take away sulfur and you take away lubrication........unless they replace it with something else that will put back some or all of the lubrication lost by the sulfur removal. Time will tell what effects ULSD has on our engine internals.

As for me, I use PowerService every fill up.....hopefully it's helping.

 

That is not true, sulfur is not a lubricant in diesel fuel. The process by which they remove the sulfur tends to reduce its lubricity (it used to anyways, not sure about now). All on road diesel fuel will have to meet the ASTM D-975 specification. That spec has been modified to include lubricity values.

As a side note, running about 2% bio-diesel (B2) will put the lubricity back. You can run up to 5% bio-diesel (B5) before running into issues with Ford's warranty.

 

The Dodge Cummins guys are using 2-Stroke oil. A fuel additive, PowerService or Stanadyne, is a all we need.

 

I looks to me like the problem is 2-fold. 1, the reduction in the parts of sulfur itself is a hit on lubrication and 2, the hydro-treating process itself harms other compounds that provide lubrication. Seems like more articles and papers talk way more about the removal of sulfur itself then the other side of the coin (hydro-treating process) but again, they both seem to have a detrimental effect on the fuel's lubricative properties.

Here's part one research article from Penn State:

Dr. Joseph Perez, adjunct professor of chemical engineering and leader of the project, said, "Low sulfur diesel fuels mandated in California will soon be required in all states to enable diesel engines to meet the 2004 emission regulations. Removal of sulfur from the fuel causes severe wear problems in fuel injector systems."

Here's a excerpt from a study done for the U.S. Army:

Low Sulfur and Diesel Fuel Lubricity – The Continuing Saga

Since the maximum limit for sulfur in diesel fuel prior to October 1993 had been 0.50% or 5000 PPM, the refinery processing not only lowered the sulfur content but also removed trace amounts of certain polar impurities. Both organo-sulfur compounds and these polar impurities were the ingredients that gave diesel fuel its needed natural lubricating qualities.

Here's an excerpt testimonial by Stanadyne about sulfur in fuel:

"There have been numerous examples from the field where lack of lubricity in the fuel has caused premature equipment breakdowns and in some cases, catastrophic failures. This problem will be more dramatic as EPA moves to further reduce the sulfur levels in petrodiesel fuel.”

I think we're splitting hairs though.
