I have shared before but can't give you exact quantities as it's quite subjective.
I try to change my oil & filter every 5,000 miles, partly because I'm not a fan of this LL 20,000 mile oil change idea and also because I think my oil get's quite dirty anyway, possibly DPF related. I'm not really sure. I'm convinced the car like fresh oil on a regular basis, so it's gets it.
During a change I would top up oil and re-check a day later and top up again. I never really filled it right up to the max. Then about 3000 miles later I can get a low oil light. I top up (again, not fully) and might get a light on in another 2,000 miles (just before next oil change).
I reckon I must add about 500ml to 600ml in total over the 5,000 miles. You also have to factor in that I possibly didn't fully top it up after the oil change. When the light comes on, dipstick says 1/4 oil, so not `empty`. Is the light premature or set up that way? I have no idea.
I don't think my car burns oil excessively, and based on what else I've read, the EA288 does use a bit. Do the frequent DPF regens affect that? I don't know. I know that my pre-DPF MK1 PD engine never lost a drop between 10,000 mile oil changes.
I'm about to do an O&F change and I'm going to be using a different brand of 507.00 oil. I want to see if that has any impact on the regens. My change in driving from 20 miles each way to 5 miles each way certainly impacts how quickly the DPF fills up, but on a younger car, I think it would't regen as quickly. Got to accept that the DPF is probably getting tired (trying to get definitive answer on that is difficult).
It's a good car and if it needs a new DPF (or clean) at some point, it will get one.
