I'm not saying that I know everything but I'd think 15w40 would be to thick, especially when you first start the car up. Diesels use 15w40 due to the excessive heat they produce and need a thicker oil.I know that using 10w30 will void your warranty so I would only assume 15w40 would be asking for trouble??? Like I said I could be wrong.
