What type of oil uses a 2001 z3 bmw with 125000 miles

If you have the owners manual it should tell you, cause some bmws use 5 w 20 or 5 w 30 you can call a dealership and ask the parts dept. they can tell you exact. that will save you from breaking the engine. some are synthetic also not standard oils hope this helps please rate thanks

Full synthetic only. Mobil 1, 5w-30. or Castrol. use Castrol. Every 15,000 or annually which ever comes first. DIY and save a bundle.
