,....... I am wondering if there are non OE options for filters that are superior to BMW or equivalent for cheaper price. Oil changes at my Indy still run just shy of $100 so considering doing my own going forward.
Your logic is impeccable, nobody can peck that.
Walmart's Mobil1 0w-40 in the 5-quart jug is the cheapest, best way to go for BMWs.
Or Castrol Synteq Euro 0w-30 quality too. (Both for LL-01 anyway.)
Pick an oil filter based on better performance
than the usual Mann-Hummel the dealer has.
Fram Ultra is the best by far, 99% at >= 20 microns in the standard ISO 4548-12 test, typically an XG10075 ( Example Link here).
or Walmart. The Ultra has a higher dirt holding capacity than most for long life. The Fram ExtraGuard CH10075 is good, at 95% @ 20 microns. Wix makes the 57327 which is a 95% @ 20 microns, same as NAPAgold, great choices too. (Your part numbers may vary of course.)
Fram?! When I joined this forum they were the laughing stock of the filter community...,have they come so far? Seriously?
How does that rating compare to Mahle or Mann? Has anyone torn down the Ultra version and verified improved components and mfg qual?
