As PimTac mentions, that is a tough call. The 2.5T may have no LSPI issues but it's just to early to tell. Being such a large vehicle with a proportionately small displacement DIT, i would go with a dexos1Gen2 moving foward. Congrats on vehicle, they're strikingly handsome and should give many miles of reliable motoring.
