I used to use a 10w-30 weight oil in my car for a long time, and i recently switched to mobil 1 tri-synthectic and my car runs better than ever. I was extreamly happy with it. I'm not a mechanic but as far as an engine not being used to it??? thats probably his way of saying that mobil one takes away from his bussiness!! I'd use it.... good luck
