The two delo oil's...

Recommended Posts

O.K Guy's...after reading guesswho's thread where he posted an Oil analysis {see below} It got me concerned and i researched the places i have been buying my oil; WalMart & Advance Auto..both carry only DELO 400LE which in the analysis was rated at the bottom

The DELO400 MULTIGRADE SAE (API CI-4 Plus) was what was ranked at the top along with Valvoline/Cummins preminum Blue.

I have checked on the website's of Advance Auto, SAM'S Club, Autozone,CarQuest,etc.. None of the carry the DELO400 MULTIGRADE SAE (API CI-4 Plus)

Has anybody else checked this out????:shrug:

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.”

Sad to say I'm find the same thing the CJ-4 is the only oil on the market now... CI-4 is being phased out just like low sulfur diesel fuel being phased out for ULSD... So soon valvoline and the rest will follow...

CI-4 VPB has been gone in my area for 6-8 months. I used to use it but since everything went to CJ-4 I started using the Cat oil becasue its still CI-4. I only have about 1200 miles left before I change oil again and have been debating just going with the VPB. We need to see an updated set of test results with only CJ-4 oils to know which si the lesser evil. The amsoil I run in my 03 is also still CI-4, but its not cheap.:spend:

I see nothing in the info as to how and why they are ranked the way they are. Just looking at the list it is obviously based on value and nothing to do with quality.

That's exactly what I was thinking. Didn't want to point it out though :lol: But yeah there is nothing there and seems to me it was just one guy judging everything by their cover.
