Hi, i have a 2013 Bmw 750IX with the N63TU engine. Here in Norway these engines calls for LL04 spec oil, the same as diesels. I drive it on Shell Vpower fuel only.
As i understand LL04 oil in gasoline engines requires that gasoline is low or zero on sulfur because the sulfur is hard on the additives in the oil?
I dont care for longlife properties cause i do OC every 5000 miles so i guess the TBN will always be above 1.0 by a good margin . So my qustion is, is there any benefit in using LL01 over LL04 thinking of max engine protection? Is LL01 harder on the cats and may give more carbon buildup relative to LL04?
Thanks
Bjornar
