You also say he sells used cars. Was this his own "private" car? Can check from the logs how long he has owned it? (a few years or a few weeks?) The addtive sounds like graphite based (which I think is what mol(l)ycote grease is) and I would expect graphite to be used as an additive in a transmission or gearbox. Why does someone buy a SAAB (not the most economical car around) and then wants to improve its economy by 1MPG. Sorry, you have the doubt that there is some fishy smell about the car and that is why you are asking. I am only making sure you have even more doubt. Sorry :-( Charles PS. Assuming I am correct that graphite is used in gearboxes ... it might be a far fetched case that it also has a knocking engine (main or small bearings) and the graphite is used to try and lower any noise. -- Please remove _removeme_ to reply.
