That's the dumbest thing I ever heard. "Engine wasn't designed for synthetic..."
I guess there really is no limit to the moronic bullshit that you hear at a dealer. I've heard some actually mention that opening up the brakes for a bleed was not recommended. Friggin' morons. You want to know about what oil works, consult a tribologist. They'll give you the straight scoop. I wouldn't let that dealership touch my car ever again.

For what it's worth, went to my Nissan Dealer today to get the oil changed. I discussed the merits of synthetic oil (Mob 1) with a mechanic and a Serv Advisor.
Both said the X's engine was designed for regular oil and that synthetic is not the best way to go. They also didn't believe the Mob 1 filter was the way to go, the Nissan filter was better.
They didn't say that Mobil 1 products weren't good, just not needed.
Just passing on what I heard.
