OEM BMW Engine oil

  • Engine noise:
Rating 4.0

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. 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.

Pros: smoother engine, no cold noise, no oil consumption
Cons: noisy engine with old oil, oil consumption with 0w-30

OEM BMW Engine oil
Exita
  • Exhaust smoke:
Rating 5.0

I’m up to 150k miles on my B58. Oil changes every 10k miles from new. Still running smoothly, not burning any oil, pretty sure it’ll go another 50k miles at least. Personally, through 5 BMWs, I’ve always just stuck with the factory recommendation and never had the slightest issue. It’s always been the rest of the car which has gone before the engine.

Pros: engine running smoothly, no oil burning
Vehicle: BMW
Mileage: 150000 km

Sachs Shock absorbers

Well, it's home and boy oh boy does it feel tight as a drum ????????

It's firmer than the Sachs/Eibach combo; but not stupidly - you still feel the bumps, lumps and potholes as I did before, but there's no 'crashyness' over them; it just rides over them now

Pros: firmer, no crashyness
Cons: still feel bumps

MICHELIN Tires

I live in buffalo area we just were hit with 2 feet of snow the past two days. I put dedicated 20inch wheels and Michelin x ice tires on it instead of the 22” stock wheels and Michelin all seasons. It’s the most planted feeling I’ve had in a vehicle in the winter. I love how well the defrost works too. I’m start a new post tho for what is the most overkill windshields wipers available for the ix. I need them.

Pros: most planted feeling, good defrost

I ran Depos on a 97 M3 for a while, much better than the condition of the headlights when I bought the car, middle of the road for me and I have horrible night vision.

Pros: much better condition
Cons: middle of the road

My iX is terrible in snow. When there is a thin wispy dusting it slides all over, slips out on any turn. I have Michelin Primacy A/S.

Cons: terrible in snow, slides, slips
