Here's what 5k oil change intervals looks like at 45k miles (BMW/Peugeot N16 engine). Not a hint of varnish. I'm sure the piston skirts and rings look just as good. Some say 5k is too short, I say it's not.

Oils used:
- OEM Mini 5W-30 synthetic (first 4)
- Motul X-Clean 5W-30 (5th)
- BMW TwinPower Turbo 5W-30 (6th)
- EDGE 0W-30 (7th and 8th)

Mann or OEM Mini oil filters.

Nice! I wonder if the "S" version would look the same.

If you could compare it to 10k mile OCI, you'd have have some basis to say 5k OCI is better than 10k OCI.

It does look very nice!

I would assume it would. Same family of engine.

It would be hard to make the case that 5k is the same or worse than 10k. Itís just a matter of how much better, or how much of a difference, 5k over 10k makes. The sump is so small in these engines, I would assume itís notable.

Itís amazing how much dirtier the oil gets in the Mini compared to my V8 X5 in 5k miles.

In Europe we run these engines at 10k miles OCI or even longer. No trace of sludge ever.

Sludge and varnish are two very different things.

With 5k oil changes, the real question is why is the cover off at a mere 40k miles?

Cover is off because the timing chain is making noise amirite?! What do i win?!

Either that or valve cover leak. Or DI related carbon deposits. Or all of the above in any combination. Regardless what a POS motor at any oil change interval. Baby it all you want, an abortion between BMW and Peugeot.

It looks great. I wouldn't extend the interval or mess with anything. Stick with what is working!

Would longer intervals achieve the same results in 'your' application? You'll never know, nor should you care. You found something that worked.

You could easily extend that to 6k or 7.5k, at least i would.
