so SORRY for passing on info that I took the time to find from my friend, and a place here in Indy that repairs injector pumps said the same thing... go AHEAD and shoot the messenger,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, ,

 

Not shooting the messenger. Just keep hearing about people saying "my friends brothers sisters husband talked to a guys son who knows a lady that read another lady was married to a guy that works at a gas station said the sulfur lubricates the fuel."

Here is a direct quote from Chevron about ULSD

There are several diesel fuel properties other than sulfur that will change as a result of moving to S15 (ULSD).

Lubricity:
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.
The D975 specification is based on the High Frequency Reciprocating Rig (HFRR) test (D 6079) and requires a wear scar no larger than 520 microns.

I broke down this morning and bought a big ole' jug of Power Service, filled 'er up and added 12 ounces to the tank. After reading the various post, and speaking to a friend of mine that owns a small trucking company, I figured what the heck will it hurt. If nothing else at least I'll feel better knowing I tried to take care of the ole girl.

 

what ive noticed since using ulsd is that my chrome tip has got some strange residue kinda like when i used to run bean oil in my 2stroke quad. mabye the lube there adding is a type of bean or bio.?

 

Ever since I have been putting in the new fuel the engine seems to rattle more and it is harder to start and less power. This may all be in my head but I have just checked the valves and very little adj was ness. So that was not the problem. I have been driving the truck for 80,000 miles and it seems different since the new fuel Has anyone else noticed this??

 

Nope.Mine still seems the same.In fact best mileage I've ever gotton is recent.Not a lot better but better.

 

I think I am now running the new fuel..I have lost about 1mpg on this last tank.
