so the book for my 5.9 '05 sez no fuel additive is required but i put in PS grey on each fill up. does the board really think PS helps keep the injectors clean and help prolong the life of the injectors?

i like to think i am helping the injectors but just don't know.

whatcha think?

I use the PS gray/silver also. I dont run it every tank though, more like every 4th or 5th. Honestly cant tell a difference, but it makes me feel better, LOL!

 

ran a couple of tanks with lucas upper cylinder lubricant, and injector rattle is non-existant, truck runs smoother, and exhaust smells better. it is also the only fuel additive i've used, that doesn't have a 'solvent' smell to it.

 

There was now ULSD in 05. Now all diesel (on the west coast anyway) is ULSD. If you plan on keeping your truck, I wouldn't run it without an additive. I would also recommend using Baldwin 7977 FF's: they are 5 MIC. Injectors and CP3s are big $.

If your buying high quality diesel then you most likely only need to use PS a few times a year and not in every tank. My self I use Lucas as I feel it does a much better job then PS ever did in my truck and I see a small gain in mpg when I use it. I would also agree to use the Baldwin 5 micron fuel filter or the Fleetguard Stratapore filter if you can not get a Baldwin or even a Mopar if that is all you can get. FYI, many of the other brands sold at parts houses are still 10 micron and you need to use a 7 micron or smaller fuel filter.

 

and most of those brands are not water seperators. ask any fram user if they've ever seen a single drop of water, when they drain the canister.

 

I used PS every other tank and had to replace my injectors. I think its crap but thats just me. I use BG 244 couple times a year, although its $40 a quart, I think its worth it!

 

You might find this thread from another web site interesting. It quotes an independent study comparing the lubricity of diesel fuel additives.

this was discussed a while back- there are several products that did well in this test, that are more than 50% by weight petroleum naptha (about twice as much as sea foam), which is a strong solvent. products that contain that much of a strong solvent may not be the best thing for injectors, and i'm not sure how a strong cleaner/solvent can add to the lubricity of fuel. there are many that say not to run any product that is more than 20% solvent (naptha) on a regular basis.

 

What ever the products that did well in this test contained, they were good lubricants since that is was what the test was for. Even is some did contain 50% naptha, that leaves a lot of room for lubricant.

 

I run 16oz of PS with 16oz TCW3 every other tank.

spoke to the head diesel tech at my dealer and he said that these tests are done with one tank of fuel. the problems that you will see from running high amounts/concentrations of solvents (naptha) take longer than 1 tankful to show up. he said other than at the track, on rare occasions to help with a sticking injector, or to keep from gelling in very cold weather, he wouldn't use a fuel additive in his truck that contained a significant amount of solvent. for now i'm sticking with Lucas upper cylinder lubricant, as it is not a solvent based product- if you don't know the ingredients of a product, a simple smell test can give you a good idea...... update- i just spoke to a second diesel tech who said that he doesn't recommend running any additive that contains more than 5% solvent, as it breaks down the lubricating film on parts (something that would start to occur long after the 1 tank test was over), and can cause particles to go where you don't want then to go. he also advised against running more than b20 for the same reasons (not above b5 in CR's), as high levels of bio tend to act like a strong solvent.
