Well that is what I plan to do, bring my own oil. The owners manual also recommends 5W-20 SL oil. I was thinkimg of using either 0W-20 Fuchs Titan GT1 or maybe Aral 0W-30. Both are A3 rated synthetic oils. If the dealer gives me flack, I will have him do the oil change, stamp the book and then go home, dump the oil out and put the goof stuff in. I drive relatively aggressively, red line it on occassion and temperatures in y part of the world are mild to hot.
