A bit of a strange gas mileage question
I was driving the other day and for some reason started wondering at what speed the car sips the least fuel. Any ideas? I'm guessing as soon as it kicks into overdrive so that its revving as low as it can in that gear?

I drive 60 miles each day back and forth to work, mostly highway.
Average speed is between 70 & 80.
My average MPG is 27-28, consistantly.
The key to good gas mileage is to maintain a constant rate of highway speed. I don't think you'll do much better at 60 then 70. Once your over 80 the wind resistance is an issue.
A fresh coat of wax makes your car more aerodynamic.

Cruise Control is only good on flat roads (SC, GA, FL). Anything other than that and it takes more gas when it gas to climb hills (NY, PA, MA).
In the north, going to FL, I was getting about 390/tank. After I got passed the Mason-Dixon line, I eventually ended up getting 430/tank.
(This was in August when I drove from Albany, NY to Clearwater, FL).

Simple, least fuel is used when you decel in gear. Go with SEmy2k2go's suggestion, see what applies to your specific car. Everything else MPG you want to know, search; there are literally thousands of threads on the subject.

Long back I used scan gauge, it was a tool to monitor gas mileage.
If I remember correctly for California spec maxima peak gas mileage was at 1800 rpm (approx 58 mph). Scan gauge showed peak mileage as 34mpg.
But in real word all I get is 350 miles to tank which is roughly 22mpg, in city driving.

wow we have an MPG thread in disguise here, if your car is an auto you ar ein luck, cause the torque converter kicks in at around 100-110 KM/h...thats when you save the most fuel on the highway, cause when you speed up after that cutoff point the rpm rises and wasted more gas
just get yo self some jdm spoiler yo man and use the downforce on that whip yo !!!!! hehe

theres acctually a whole formula based on this, im not sure what it is all i know is that if your on the highway and hit cruise control, it should help. The more you go at a contstant speed, the better it is im guessing.

so you "save the most fuel on the highway" just below 100-110kph or just over that? And dont the revs rise every time you speed up? lol

I've heard that waxing creates a smoother surface. So it will probably help, but be minimal.
At highway speeds you can also retract your antena. It makes no sense to take one step forward and one step back.
