guys, question
motor oil Im changing each 5k miles, even previous owner keep BMW interval 15k. Im using Castrol 10W60, as recommended (even believe on the market are better oils).

But what about air and cabin filter?

With oil change I replace also the air filter (Mahle LX1590), previous owner made it 1,5 year a go -5k miles. But the origin filter looks ok, so I belive the change wasnt necessary. Im driving in normal climate, no sands, no dirty roads, no mud, no drive in snow... So its change w oil necessary? I guess in 2 years or 15k miles it should be ok, what you think?

W cabin filters the same story, origin looks clean...
