Welcome to the ECO MT in the mountains. I drove from Denver to Grand Junction and back on 11 gallons of gas - this works out to better than 45 MPG over Vail Pass and the Continental Divide on I-70.
That will only work if you use an easy foot and let the car loose speed up hill as well, basically using a constant easy foot up hill and downhill. This only really works on small hills where you don't loose to much momentum/speed, otherwise your missing the opportunity to utilize DFCO. Remember in DFCO you are using no gas, which more than makes up for any gained speed gassing on it downhill.I usually speed up on the way down a hill to make it easier on the way back up :tongue: maybe it's sir Issac Newton giving us a hand.
I have not looked into this as DFCO seems to work much better on my auto cruze than my previous car, a 2004 cavalier auto. On that car the manual trans could use DFCO in any gear, but the auto I believe was a certain gears and the RPM range was tighter.Agree. DFCO properly utilized significantly bumps up the Cruze's fuel efficiency in M32 manual transmission-equipped cars. In 6T40 automatic transmission-equipped Cruzen, not so much.
