Question about 1994 BMW 5 Series
What type of oil filter do I need for my bmw 540i series and do they all have 8 cylinders?
Is it ok to switch back and forth from synthetic to regular motor oil?
1. You need an oil filter made for your year and model of bmw.
2. The 540 is the 8cyl version vs the 528 is the 6cyl version
3. yes, you can go back and forth from regular to synthetic oil with no problems
