NO! It is truly the sound of less friction!! Since you put in 3k per mo or 36k per year, it would be interesting to know if you experienced a range of BETTER fuel mileage. In my case the range was/is between .5 to 3 mpg. For me it seems to hover at 1.5-2 mpg. So for example if you got 37 vs 35 mpg, over a years time and 36,000 miles you are saving 56 gals x 37 mpg =2,072 miles (1029-973=56 gal x 2.5=140 year/12=11.67 per mo).
