Hi members,I wanna change oil in our 745i 2004 with 180,000..I've read about Liqui Moli that is suppose to be good. I wanna go with 10/60 instead of 5/20 because a little thicker meaning less smoke as the seals are getting older. I was told that by someone who's try that in his 225,000 m3..I've read a lot of post on oil on the forum. Cannot seem to make up my mind. Any advice would be greatly appreciated.
