The exhaust system on the fedex truck would actually be designed by cummins instead of in the pickups the system is designed by chrsler/mercedes. This has me wondering if they inject fuel post turbo instead of using in cylinder regeneration which causes fuel dillution.

This looks like the same vehicle just from a different side.

Next time I get around this truck it should be real easy for me to find a post cylinder injection system if it has one. On my to do list!

Just met with the customer today.

We changed the filter "Fleetguard LF3970" to "Donaldson P550428" and topped of oil - about a quart.

Took a look under truck for post cylinder injection.

Forgive me as I am not as familiar with these systems as I could (or should be).

If it were a post cylinder injection system wouldn't I see an injector with a fuel line near or before the DPF? If so, I did not locate anything that would resemble a post cylinder injection system, leading me to believe it is "in cylinder injection"

Does someone have a good picture of a 6.7 post cylinder system?

An '07 6.7 may not even have a DPF system on it-may not even have a catalytic converter either, as a medium-duty truck. It would look a lot like a gas cat, but would be larger. Wonder which media the Donaldson uses? I can't imagine it's as good as the Stratapore you took off.

I know it has a DPF just not sure the type injection system -pre or post cylinder.

Standard Donaldson media. 20 micron at 50% efficiency.

What are the Fleetguard specs, information is lacking on the site?

Unfortunately Donaldson does not make an Endurance version for this application.

That oil has almost the EXACT same add-pack as Rotella T6 5W-40.

Thought Amsoil would you OB Ca add-pack, like they do in many of their oils - seems like Mg/Ca mix is the only way to meet CJ-4....

Yeah magnesium is a detergent to make up for the lack of calcium. You multiply the magnesium count by 1.6 and then add that number to the calcium numbers and it will look more like the CI-4 plus numbers.
