JaguarXJL15, thicker oil I do not think is the answer as the VVT system needs as thin of oil as possible. The detergent may correct things, it may not. This is where you have to answer the question of : Is the damage due to build up or is it due to wear? If it is build up, then yes, this detergent you are looking at should help. If it is due to wear, that is not going to do a single thing for you.
