2009 BMW M3 Sedan: In Need of Oil
December 06, 2009
Yesterday our long-term 2009 BMW M3 informed me that its V8 needed a quart of oil. Easy enough. I checked the owner's manual, which stated very clearly that BMW recommends Castrol brand and the engine needs synthetic oil in a variety of acceptable viscosities.
I bought a quart of Castol Syntec 10W-40 and poured it in. Cost? $6.99 plus tax.
