Just think how much the mileage would have improved if you drove 60.Just finished a highway trip. On the first leg I set the cruise control on 75mph and got 23.8 mpg. The computer and the hand calculation were the same. On the return I set the cruise on 70 mph and when I got into town I dropped down to 65 mph. On this portion the computer said 26.1 and the hand calculation was 25.1. When I put gas in the Ex after the return trip the car was on a slight incline with the front of the vehicle pointing down. I don't know if this effected the fill up. Funny, just going 5 mph less and I got 1.5 more mpg. Still very pleased with the gas mileage for my V6 FWD 4600 lb SUV.

That is why I only fill up every 4 - 6 weeks. Your too quick today Vince. I was going to add to my other post.Just try to imagine how much gas you would save by not driving it much...Oh wait, Peter, you can!![]()

It seems that optimum (advertised) mileage is attained at 55mph. The following is what you can expect to lose in efficiency;
60mph - 3%
65mph - 8%
70mph - 17%
75mph - 23%
80mph - 28%

I hear you. In most if not all areas of Ontario the max speed on the highways is 100 kmph (60 mph). I must confess that there are times I do set the ACC at 110 (almost 70).Although I appreciate the effects going slower has on MPG, it's just not very feasible to drive less than the speed limit on a highway. Sometimes it's dangerous, the rest of the time it just feels so incredibly slow. 70 MPH is a good speed to me.

I couldn't agree more! When we go to North Carolina from Michigan in the summer, if you get into those southern Kentucky mountains and aren't going at a decent clip - those trucks are on your tail like you wouldn't believe.
Up here, I don't have such issues. And I-75 through Ohio and northern KY are fine - but the mountainous KY is tough.
Man I don't know what highways you guys drive but here in South FL on I-95 or the Turn Pike if you are below 70 you are going ubber slow holding up traffic or about to get rammed by a Semi.... heck I'm usually at 75-80 and still get passed a lot. That or it's too slow, if I drive to GA last thing I want to do is drive below 70 lol.
In Florida we have some towns that are known to be big time speed traps. There is one town outside of Gainesville called Waldo. You do not want to be even a few mph over the limit. They will set up speed limit signs less then a mile apart with different speeds. AAA even warns its customers about that place. There are alot of 2 lane roads I travel. When I got the really good gas mileage the other day I was driving the back roads from Alachua to Stark to Inverness. Nothing but old farm highways. It was very pretty country, but the speed limit is not like on the interstate. I just put it on cruise and got the 31.9 mpg and obeyed the speed limit. Which reminds me, I love the fact that the EX on the LCD screen will post the speed limit on the Nav setting. That comes in handy when I do not know the speed limit.
