Do us all a favor and try it for one oil change cycle and get back to us with your results. I can tell you first hand the fuel additive / injector cleaner does work. My '13 Toyota goes 6 miles a day below 40 mph and after 6 months it starts running rough. So about twice a year I dose it with Lucas to restore the lost power and rough running. I have farmer friends that will not use any thing but Lucas additive and oil in there $80K tractors, they say they idle better and pull better.
