Bokusārēsā : good info!! I usually cruise at 50-65 mph in those designated speed zones (5th or 6th gear), so my RPM does not get that high…..but still sounds like a Auto would beat me out MPG wise… some of the time. A Big.. big part comes to who the driver is/ driving style, light foot or lead foot (no Indians here), … along with some other main factors. |
I didn't log it or anything so take this with a grain of salt. Before I added my SC, Headers, and tune, I was averaging around 31 mpg in combined driving. And up to 33-35 on the highway. After getting my SC on, it dropped to where I average 26-28mpg in combined driving and normally 31 mpg highway, though recently I was able to average 33.1 mpg. So it's not too bad. But truthfully, I sit around 26-28 9/10 times.
