Diesel owners and Ultra Low Sulpher Diesel Fuel

[CyberVet65]

Beware and look under the truck/motorhome.
When they removed the lead from gasoline for unleaded gas. There were some problems with engines that used the lead as a lubricant in some of the engine components.
Well, folks, they just did it to us diesel owners. Granted it was an infintesimal (sic) amount. But it was a lubricant for many of our engines o-rings.
The failure mode in the Ford 7.3 diesel is the o-rings in the fuel filter/drain lever fail. Fuel starts to leak. Some leaks are making the vehicle undrivable. The fix is a couple of "viton" o-rings for about $5.00. Of course, Ford is selling a kit for $39.00 or if mis-diagnosed is selling injector pumps for $800.00..
In some Dodge diesels the injector pump does fail. You will see fuel leaking from the injector pump.
You can replace the missing lubricant by adding an engine additive.
Ford folks can get the o-rings from a link on the Ford diesel web site. http://www.thedieselstop.com
Well, I guess that we can clean the air by losing fuel on the ground rather than burning it in our nasty diesels. So much for having a million mile engine in my truck. I expect that sooner or later the o-rings on my injectors will be effected. Meanwhile I will keep running an additive. I prefer Stanadyne. Some folks run Power Service or Lucas additive. Whatever it takes.

Thanks Chet. Someone on here recommended a little 2 cycle oil in with the Ultra Low. I have 4 diesel engines, (tractors,skid loaders etc) sorta concerned and so far I can't get the reg. sulpher dyed diesel.

The ingredients in Standyen, etc seems to be mainly kerosene so I'm not sure what good that'll do me. But the diesel in Minnesota has soybean oil in it which is suppose to help ????

I use the Standyne Performance Formula during the winter. Here in Utah the switch from #1 to #2 diesel happens right after Thanksgiving. I run a tank and then add the Stanadyne. It drops the "pour point" down to about 10 degrees. This isn't helping a whole lot since we have have -10 to -20 degree temps all week.
I do notice the Stanadyne increases the quietness of the engine and increases the mpg slightly. I have used it for the last six winters and it seems to wrk as advertised. But I guess Lucas and Power Service and the other additives will work as well.
I will be changing the 0-rings in my drain valve this weekend. Hopefully it will be above 10 in the garage!

Hi Guess I,ll just add a little more Power Service and hope for the best, really not much more we can do, except add our fuel elixir of choice, and see what happens.

If you will check with your supplier they should be able to tell you if the fuel is winterized.It should be not jell at the lowest expected temp for that area. I drove commercially up there for 3 years and did not use additives. I did not idle the engine when not in use and never had any jelling problems. Now if you fuel up in south Georgia and go to Mn. you might have a problem
