The BMW dealership is the only place you can get it.Travis Williams said:hey! i am new to the board and hope you guys can help me out. does anybody know where i can get the castrol formula rs 10w-60 that BMW reccomends? the castrol site says they do not make 10w-60??? any web sites i can order it from? i guess i could have the dealer do it, but i enjoy doing all i can myself.
