Mine doesn't use at all. Used Castrol Edge 0w40 for the last 7 changes. 131.000km now.
But before I removed the DPF, the oil level actually got higher. So much that I started to be worried. The regen cycles are real bad for the condition of the oil. So bad that some cars self ignite. And not just Hondas!
I sent Castrol an oil sample before I removed the DPF because I was worried that an injector leaked because of the rising oil levels.
They said the oil was OK, but it had way too much diesel in it. And I was recommended to replace it as soon as possible. I only drive approx 10k between services. Can't imagine how the oil is when you drive so called "long life" intervals. (VAG, BMW etc)
Another good reason to ONLY use oil with the best quality
