I have a high mileage 2018 BMW 330i xDrive F31 (B46) with 156K miles. It has had regular dealer oil changes its entire life with only BMW spec 0W-20 LL-17 FE+ or equivalent prior to the LL-17 spec. I'm hoping to prolong the engine as long as possible, as it currently has no leaks, concerning sounds, or other engine issues at the moment. I live in Central Ohio so I'm good with a 0W vs 5W oil.
However, I'm concerned that the 0W-20 may not be enough protection due to the high miles and potential wear. I was thinking of upping the viscosity to a 30 oil to get some additional protection, but I keep bouncing between oil with LL-17 or LL-01/LL-01FE specs vs just a "generic" Euro oil like Castrol Edge or Liqui-moly
Does anyone have any oil experience with late-model high mileage BMWs with B series engines? Any recommendations?
