So X6 owners that don't park their cars in a heated garage during winter, be careful. Also, that the components that keep the timing chain tensed, were a bit too thin, from start. Combined with a thickened oil during winters, at cold startup and drive off, , you might get into this kind of huge trouble. Also please do replace your timing chain at aprox. 80k miles (doesn't matter what mechanics say) and also do replace your transmission oil, even if they tell you it has a lifetime warranty.

I think you just pushed me over the edge to switch from 5W30 to 0W40 year round in my 2013 X6M....certainly I think this should be the standard for cold climates...particularly in high performance engines. Thoughts?
