I stopped by my local Dodge Dealer this morning to have the oil changed on my wife's Durango (1st oil change was free, no appointment). Anyway, once the change was done, I asked the service tech the cost of an oil change with synthetic oil for my Challenger. He said it's about $80 (holy cow) but they are recommending an oil change using regular oil with BG MOA additive and Fuel/Air Induction Service. I never heard of this stuff and I usually do not like using additives, but I am just curious, does anyone use this stuff and what is your opinion?
