How much DPF?

Got my first oil change today at 11,500 miles (half on the highway).
On the receipt it says they added 8 units of oil and 2 units of DPF.

I have no idea what quantity a "unit" of DPF is but I guess I was expecting them to add more.

I know this will vary by the mix of driving a person does but:
How much DPF was added at your last oil change?

I don't recall ever seeing an amount or a unit. Only that it was refilled.

Unit could be a liter or a gallon. 2 liters would be very little. 2 gals could be possible. How do you know if they even filled it up all the way?

I see on the internet where units are sold in 2.5 gal jugs, so two units would be about 5 gals. Full is about 6 gals, so that would be about right.

2 units for me, I did a search on the part number and it equated to 2.5 gallon jugs

To clarify I assume you are speaking of "DEF". "DPF" usually stands for Diesel Particulant Filter.

Unless they added two diesel particulate filters to his car? Anybody ever wondered how they make the urea solution that comprises the fluid? I keep visualizing a bunch of guys standing around pissing into a crock!

Just ask them to fill the tank and top off the other one. If they agree to do both, you are covered.
