The consensus seems to be using Delo, Valvoline Premium Blue or Amsoil Synthetic for engine oil. I personally think they are all equal at over 20F. From 0-20F you start to see a little difference between the first 2 and the amsoil since those aren't synthetic. If your engine has to start in weather under 0F a lot, I would really consider synthetic oil.Oil filters seem to be the cummins brand fleetguards or stratapore. There are some other brands out there that are good. Fuel filters, I just use the NAPA Wix ones but maybe someone has more input on that.

this is a review of popular brands of diesel oils and how they rated in TDR's test: http://forum.mopar1973man.com/downloads.php?do=file&id=77 i run valvoline blue with the cummins "C" and Donaldson Endurance filters (ELF7349) they are more pricey, but filter the smallest particles. i have run fram,wix, and the walmart mopar filters in the past.

I run a variety of oils, usually what I find on sale. My latest sale score is 12 cases of Valvoline Premium Blue the O'Rielly's had on sale recently. I used to use the Fleetguard Stratapore filters. They are great filters but cost about triple what a Baldwind filter costs when you buy them by the case. Baldwins makes great filters as well but at a MUCH lower cost.

HOW ABOUT MY 6.7-LITER ENGINE….

If you have a 6.7-liter ’07.5 Turbo Diesel truck it is recommended

that you use a CJ-4 lube oil. Why? Again, issue 54’s article has the

reason behind CJ-4 oils.

“The EPA tightened their exhaust emissions thumbscrew on diesel

engines starting January 1, 2007, to reduce particulate matter

(PM) and oxides of Nitrogen (NOx) emissions. To meet these

requirements most diesel engine manufacturers are resorting to

the use of diesel particulate fi lters (DPFs). A DPF differs from the

catalytic converters we have used for years on gasoline engines in

that a DPF actually fi lters the entire diesel exhaust stream.

“On the surface you wouldn’t think this would be a big deal—

Europeans have been using DPFs for years. The difference is that

Europeans don’t accumulate mileage like Americans and they will

tolerate much more frequent service intervals. Our EPA has decreed

that the new DPFs must go 150,000 miles before needing removal

for cleaning. This means the soot collected in the DPF must be

burned off in the exhaust system frequently if trap life is to exceed

150,000 miles without removal and cleaning.

“I don’t have to tell you that diesel exhaust is relatively dirty.

It consists of lots of soot (that’s what turns your oil black) and

unburned residues from both the fuel and the oil. Sulfur in the

fuel can signifi cantly hamper DPF performance. That’s why ultra

low sulfur diesel (ULSD) fuel was introduced in the fall of 2006.

Phosphorus and sulfur in the lube oil can shorten DPF cleaning

intervals considerably. Phosphorus (P) can ‘glaze over’ and plug

the tiny holes in the DPF, making the openings effectively smaller

and quicker to plug. Sulfur can ‘mask’ the DPF, making it temporarily

less effective. Sulfated Ash (SA) in the lube is thought to build up

deposits on the DPF over time. These deposits that originate from

diesel fuel and lube oil then make the DPF effectively smaller and

quicker to plug.”

WOW! I did not no there were 2-different types of DELO on the market:shrug:..i just changed my oil w/Delo i bought from Advance auto...Its the" LE" version..oh..he$$...

what about the Delo at WAL-MART
