Oil for E23 728

[roadcrew666]

For the Oil Change you need 5.75 litres of oil(incl.filter change, you should change the filter). This also should stand in the owners manual. I don`t have tryed Würth cleaning fluid. I change my oil once a year or all 12 tkm, until today i have no problems with my engines, and i owned over 8 BMW`s until yet. The last BMW e34 535i i owned had run over 315tkm, and i sold the car with great running engine. I only use CASTROL Oil, prefered 10W40 or 10W60.

P.S. My English isn`t very well, i don`t use it for years.
