Now that gas is about $3.39 a gallon in SoCal, mileage is important. I drive about 25% City and 75% Highway, and I'm always getting 30-31 mpg average. I use the cruise control constantly, and it really seems to help. Anyone else trying to maximize mileage by using their Cruise control? And is there a danger in using it all the time? I use it even on short stretches around the neighborhood. Anybody here have to get their cruise control repaired? Also, is this cruise control electronic or does it use vacuum hoses like older cars did. I remember way back when a vacuum leak would really mess up things and cause unwanted consequences like sudden acceleration!!
