FWIW, the SLX is all I will use during the warranty period, but am a little concerned about using it long term due to the 30wt (thin). The Motul 5w-40 tailor made for the M57 engine looks interesting... |
Glad you brought up MM... I felt it was getting way too geeky.
People often read that BMW manual and say "well, ard, you are right, it does say you must use the 'recommended' oil- but if you can't get it you can top off with other oils...but BMW
must have just made a mistake, or wrote that section poorly, because such a convoluted recommendation makes no sense."
But when you understand that Moss Magnussen requires a manufacturer to provide ALL service items that are
required to the consumer at no charge, you realize that BMW will provide oil changes for free- so they state you much use BMW oil for the fill- but they do not want people coming into the service bays and saying 'top me off', hence they carve out the top off oils.
This is their legal policy- many dealers will top off, but BMWNA will NOT pay the dealer for this work.
This is, simply, the reason for BMWs convoluted and nonsensical oil policy in the manual.
And again, this conversation is not "what oil is best"- there are likely better oils than the BMW oil.... just that there is only ONE oil that BMW allows for oil changes.
