no luck, we are still without a visual[:-]

 

I down loaded a pic on my prfile, but it doesn't show up like all the rest of them do. Not sure how to make it show up after I send a note.

 

Drew,

The below info is what one persons research has found out about fuel filters we have been using in our 3rd Gen CR engines. You may want to add some of this to the CTD FAQ section. IIRC ah64id also called Amsoil to get the info about fuel filters and they had not heard of the new Cummins requirement of the 7 micron fuel filter for all CR engines.

-------------------------------------------------------------

The below info was made possible by a lot of research by ah64id at dieseltruckresource.com. This is all of his hard work and not mine. I will add that not all fuel filters are good at stripping water out of diesel fuel like Fleetguard and Baldwin filters can.


So after reading a few threads on fuel filters and getting conflicting information I did some more research. As it stands right now I can only find 2 fuel filters that meet current CR specs. Fleetguard, (Cummins/Mopar) and Baldwin. Wix isn’t close and Donaldson isn’t.

Current specs, based on TSB 14-007-06 5.9 CR motors require a 7 micron absolute filter. While the TSB only talks about MY06-07 I called several dealerships and asked for fuel filter PN's for older than 06 trucks, all come up with 68001914AA, the new 7-micron absolute filter. So the searching began.


The Fleetguard FS18000E is absolute at 7 microns (96% efficient at 5 microns) but the gasket isn’t ULSD compatible, so use FS19856 (same filter different gasket)...this is the OEM filter. Has a 14 gr. dirt holding capacity


Baldwin PF7977 is nominal at 1-2 microns and absolute at 5 microns, has a 24gr dirt holding capacity.

Donaldson lists P550785 is absolute at 10 microns.

The WIX 33585XE is nominal at 7 microns. 33585 is nominal at 10 microns.

I am sure there are other filters being used but those are the big ones I know of.


Absolute is 98.7% efficiency and nominal is 50% efficiency.

I have also read, but not verified, that Bosch specs a 5-micron filter for the CP3, and that GM now uses a 2-micron filter.

 

Where did you get info that said not to use synthetic oil until 35-40,000 miles? Just and FYI, I went to synthetci oil at 10,300 miles and I don't use any oil. BTW, I also run very thin 5w30 HDD oil. If you work a diesel engien like it was made to be used you can use synthetic oil at 7500 miles. Now if you don't work the engien and drive it to work or to the store then yes it may be a good idea to wait until 20K to give the rings more time to seat, but I have never heard or read about having to waiting until 35-40K to switch to synthetic oil.

 

Ams oil site for one, Syn stops the break in process, you have very little ware and diesel take a while to break complete in.

Hell people have been posting there getting better fuel mileage after getting over 30000 miles.

So let it get good and broke in, I bought mine with 26000 miles on it and the MPG sucked the first few days I drove it around town, but then I hooked my enclosed trailer with 5000 pounds in it, I was getting 12 mpg at first but after 2 weeks of working it hard I went to 14 mpg with the trailer.

My truck must have never been loaded down, and worked like there made to do, to finish breaking it in, so give it the time, you will have the truck for a long time if you want to keep it
