Use it in my merc van - was using BG stuff for a while, worked great then I stopped when my supplier moved, 18 months in and limp mode was there every trip. Am now using Nitro+ or BP alternative plus a lucas additive, it is almost back to normal. Think the Merc will be cycling more crud than your newer XV but I would do it at least once a year if using branded fuel throughout the rest of the year.
Will be trying the Torco product as well in future
