On the Blauparts website there is listed an antifricton treatment specifically for VW's and Audi's by the name of Lubro Moly Antifriction Treatment which they say gives noticeably better fuel economy when used in a VW or Audi engine. They also claim it reduces engine wear. That would be my reason for using it plus better gas mileage would be a benefit as well. My 2011 Tiguan owner's manual says not to use any additives in the oil. Does anyone know if this Lubro Moly antifriction stuff is any good? Alternatively, if one wanted to reduce friction and get better mileage, are there other better products to use such as Lucas Upper Cylinder lubricant? All responses will be appreciated.
