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?
