No I do not use cruse control. I pride myself for having a pretty steady foot. I don't like the jerkyness of cruse when I have to hit the brake to slow down and when I reingage it. I do have a issue on my streach of traveled highway, everyone does 75 to 83 pretty steady. I drove my 2011 Fiesta the same way and got 42 to 44 mph out of it. When I did all highway miles @ 80 mph I got 29 mpg. Ouch!
I have used the "S" gear once or twice just to test it out, but it doesn't feel right with out a clutch peddal. I Drive with it in "D" pretty much all the time. Over last weekend I did disconect the battery and checked all the electrical connections on the fuel injectors and in the engine compartment to make sure nothing was loose. Just filled up this morning, will know in a couple of week if it changed aything. If the computer est. is any sign of the future MPG's I appears to be headed in the right direction. But don't want to get my hopes up before the chicken's hatch. I will post my results when I fill up again. Also When I tried out the "s" it showed I was in 5th and I was able to bump the up arrow again an mine did shift into 6th. Done it a couple of times.
