is it really true that the ULSD has less lubrication properties than the LSD? or is it just a myth. I run Power Service just in case but have always wondered

Yes. The process of making ULSD has the draw back of stripping out some of the lubricitors in the fuel. It is not the fact that the fuel has less Sulfer (ie Ultra Low Sulfer Diesel) it is the way in which they have to refine the fuel to remove the sulfer that causes the lowered lube ingredents. After all if you really think about it sulfer in itself is a rock (at least a mineral, that can be in the form of a solid rock form) and as such would be a poor thing to have in the close tolerances of todays injectors. Unfortunatly it's removal has the side effect of removing the good stuff, lubricitors that are needed.

i have ran this same mix on my 6.0 for 4,000 miles with no problems to date. when the 2 trucks have the miles on them ill post my findings.
Paul, Is that 16oz of one in one truck, and 16oz of the other in the other truck. Or is that 32oz combined in both trucks at every fill up...Either way 16oz or 32oz seems like a lot. Most of the additive I have read recommend 5-6oz per tank full for a regular treatment, and 12-16oz for a cleanup treatment.

Just trying to understand a little more, because I think we could get a lot of good info from a study like this!!!

lokiwolf what i do is buy a case of valvoline multi-purpose 2 cycle oil. its the low ash tc-w3 stuff poor 160z out of the bottel and then add 16oz of power service diesel kleen to it,that makes 32oz or one qt. the drivers add 1 qt very fill-up, i use this mix to make it easy on them to add. the 2 cycle is for the lubricity additive and the diesel kleen is for a cetane booster. i use this same mix on my truck. both the test trucks reported a smoother running engine and to date a .5 mpg average gain. the main purpose is to get less injector plunger wear. not getting any good anwsers about it i decided to do the testing myself, we tryed the ford pm-17 and pm-15 but seen no gains and the injectors i replaced had scoring on the plungers from lack of lube all this after we started useing the ultra low sulfer diesel.

Some day, someone needs to teach me the concept of spending over $6K for an engine in a +$40K truck, then worrying about putting cheap non-approved fluids via the fuel in said engine.

I could understand the concept if you could only buy approved additives from Ford for goombaw buck. But every auto parts store and truck stop (yes, central AK has them, even DJ) has more than enough approved diesel additives, why put crap in when you don't have to and put your engine at risk?

I don't get it.

will do:Thumbup: in a week or 2 the trucks will have the miles on them and come in for regular maintenance,at that time one injector will be removed and inspected.
