Ideal speed for maximixing mpg
6-speeders
I have changed my driving habits from city to highway.
On City I used to make an average of 20 ~ 21 mpg.
Now on the highway, I drive at around 75 ~ 85 mph and I am averaging the same if not less
I am trying to figure out what is the ideal highway speed to maximize mileage per galon. Gas prices + tolls are driving me crazy.
feedback please

What is maximixing?
If you look in the owners manual, they have a list of what speeds you should max out at in what gear for absolute best fuel economy. dunno if that helps .. but I get the best in my 5AT at like 70 (exactly 2krpm)

Try to drive in 6th gear and between 2000 and 2500 rpm. I get between 27 and 28 mpg regularly.

Don't go over 65 in 6th. At 65 your pushing a little less then 2500 RPM. Once your into the 75-80 range that jumps to almost 3K RPM, once your at 85 your at 3200 or so RPM. Helps to stay out of vtech. I know everyone zooms by you at 65 though. That's what you have to do.

the AUTO guys have better luck in this matter. They can push higher speed with the same RPMs as us.

In general...it's the LOWEST speed possible on the HIGHEST gear without bogging the transmission. Anything faster and it'll be an exponential climb against air resistance.
Personally I wouldn't cruise above 70 if I wanted to maximize gas mileage. Problem is can you patiently cruise @ the speed limit?

The national speed limit used to be 75 but was lowered to 55 MPH. It was lowered not because 55 MPH was safer, but because gas mileage was better at 55 MPH. (think 70's gas crisis...)
Can you take the slowness of driving at the speed limit?? I cannot and only get around 20-23 MPG
Time Vs. Money dude...

very valid suggestions here, thanks folks.
I will try lowering to 65 mph. And yes, I can say that the faster I go, the gas consumption increases exponentially. The good think, I am no longer in extended stop-and-go driving conditions.

Holy cow guys. I get ~30mpg in my 3.0cl going 79mph (right below 80, s/l 70, no cops bother me) on long trips. I find it hard to believe .2L makes that much difference at such low revs. 79mph = 3K rpm in my car.

an adult perspective
68mph = 2250 rpm = consistant returns of over 30 mpg. Unofficial record holder for most 500+ miles-per-tankful from an '03 CL-S, unofficial record holder for most miles-per-tankful from a single fill-up, as recorded here:

I avg 28 mpg on the highway traving 75 miles/hr. (CL-S 6sp)
Never ran a full tank with just city driving. I would think that would be around 24 mpg because i tend to run up the tach between gears.

I am driving @ 67 ~ 70 mph and I can see some difference.
I will post numbers when my tank is empty.
It is crazy how much gas the engine will suck above 70ish.

With the stop and go traffic thru providence, I usually get more like 21-22...
My brother stopped driving 75-80 in his v6 tacoma truck and started driving 65. He saw his gas mileage jump from 19mpg to about 23mpg...
EDIT: Truth be told, I do routinely crank it up to 90mph when the road opens up

This time I changed habits on the last half tank, increasing my overall average mpg to 23 which is better.
I started to drive below 70 mph.
I will post number on the tank I filled yesterday. I should be able to be around 25 mpg which will be a record for me.
Now that I remember, when gas was not an issue (like near 2 years ago) I used to drive over 80 mph at I-95, and a tank will last just 250 ~ 260 miles
Thank you guys.

If I can maintain 75-78 MPH 32+ M/Gal is normal for my ride with CT blower and full CT exhaust. The cruise control with the blower hurts gas mileage because it appears to be overly sensitive and opens the throttle more than is necesary on catch up. 517 miles on one tank load once! ----- squarecircle -----

Well I live in Baltimore City and I drove to Salisbury Maryland last Sunday. Its about 123 miles. I filled the tank up before I left and hopped right on the highway. I never went above 70mph except in passing situations. When I was on route 50e I sometimes dipped down to 65mph and lower. I kept the cruise control on and enjoyed the ride. BTW I have an auto CLS. I got about 200 miles out of a half a tank. I drove about 90% highway and the rest city mileage.
I don't believe thats too bad at all. I believe this past week with 95% city mileage I got around 160 miles out of a half of tank. That includes having my moments of fan and gunning my engine.

I dont know about you guys, but its hard to cruise going that slow...Going faster gives me a rush...I cruise around 75-80 most of the time. Once in awhile i'll just punch it and go around 85...makes driving more fun..

Just made a trip from Philly to Richmond, VA and back. Two of us in the car with some luggage. Drove at about 75mph for 520 miles. (Would have gone faster but the holiday traffic didnt allow it. ) Got 31mpg with the 6spd. Not bad for a 260 hp sport coupe.

OK I managed to get 360 miles with 15 gallons. 80:20 highway:city driving.
Highway driving was 65 ~ 70 mph range.
It was a good improvement.
