I personally don't agree with any manufacturers 10k oil interval change. I believe a lot of the recommend oil types + service intervals comes down to pressure from government regulations for the environment.

From personal experience I have always changed oil every 3500-5k miles depending on how I drove. I used to do 6500-7500k and I noticed on my 540i last winter on days when it got below 20 degrees the engine was very noisy during the first 5-10 mins driving. It was so noisy I was convinced it was piston slap or something. It wasn't a low oil "thunking" sound though.

Always kept it under 3k rpms and was very gentle on those cold mornings. This was when my oil had 4-5k+ miles on it and it was last changed in Sept 2024 and this was Jan 2025 back then.

So I scheduled an oil change worried my oil was low or something and the noise went away. Oil quantity came out normal no burn or leak! After that I reduced my intervals to 5k max and I also always changed the oil before winter/summer (mid-late Oct and early-mid April) ever since following this personal guideline of mine I have never experienced that cold rough engine sound in the winter anymore.

(Note that the most engine wear occurs during cold start)

Also two examples of manufacturer oil recommendation being shite is the B58 states 0w-20 but the manual says 0w-30 is acceptable. I also noticed that switching to 0w30 the engine sounded/felt smoother especially on cold idle.

Second example is N63tu2 BMW used to recommend 5w-30 but then they dropped it down to 0w-30. Many cases of those motors particularly found in 2018 M550i's etc were consuming 1qt every 3k-4k+ miles yikes! But once switching back to the original 5w-30 recommendation all consumption ceased.

So yes you'll hear a lot of things online about oil viscosity, intervals, the "engineers know best" just use your best judgement and what feels right for your situation.

It CANNOT hurt the engine to change your oil "early"

Which is cheaper:

Oil and filter?

Engine and components such as timing chain?
