When I recorded the 54 mpg tank, it was without the SG. On this most recent venture I had the scan gauge and noted that I easily got up to 53.5 mpg in the hills of south east PA/DE/MD, however when I hit the gently rolling hills of Virginia and the Carolina's, I struggled to get 50 mpg. I'm driving an automatic, so no EOC, but I do coast in gear as much as possible and thats where this observation comes in. It was quite frustrating watching my mpg tick down from 53.5 to 51 as I would climb those gently rolling hills only to find I could not coast enough distance to make up the loss. The best technique I could come up with was to minimize the loss going up, going as slow as 45mpg so I wouldn't take a big hit, then gas it a bit to get up past 50mph then just feather the throttle for as long as possible, but it still took what seemed like 30 times the distance of the climb to gain back the loss and if there were several hills back to back, it was just a loss. I'm looking for advice on tackling this type of terian and to see if others have noticed this????
