: After picking up ZweeTT yesterday, the fuel tank was almost on empty. I filled up this morning and calculated my mpg at 20.08! This was all city driving as well. : I ran only Amsoil in the car since I bought it (last October) until I switched to Royal Purple this past July. : My mpg on Amsoil was consistently in the 14.8 - 16.5 range, usually hovering around 15 and change. : Since the Royal Purple, I've gotten consistently between 18.0 and 20.0mpg. The *ONLY* thing that I changed was the oil. I'm sold on this stuff :-) : BTW, this is the 'normal' RP, NOT the racing formula. > the have "motor oil" "heavy duty motor oil" and "racing" which are you using and which weight??? thanks in advance!!!
