Default My MPG experiences

My MPG experiences
I have noticed a few people comment on their mpg being better at certain speeds. I have 20,000 miles on my ram and this is what I have experienced so far:
I drive about 60 miles each day. Of that about 50 highway and 10 city. My truck has stock 17 inch rims with stock tires and 3.55 gears. It's the crew cab with the 5 foot 7 inch rambox bed.
I make sure that every time I fill my tank up I reset the MPG average, so all of these numbers are over an entire tank of gas.
Daily commute MPG's per tank
Average-20.0
Best-22.8
Worst-16.4
Long trip commute MPG's per tank
Best-24.2
Worst-22.2
Things that help me out:
-Speed!!!! I have found that if I go over 60 mph the MPG's drop. The best speed for my truck is right around 55mph.
-Coasting as much as possible, meaning do not ride close to people so that you need to be on the brakes a lot. Each time you hit the brakes, you waist gas. I try to leave plenty of space in front of me so that if traffic backs up I can slowly coast to a stop.
-keep that little eco light on as much as possible. (shuts off 4 cylinders) I have noticed that once I get up to speed I need to let off the gas slightly so that the eco light comes on. Then I can maintain my speed with the light staying on.
This is what I have experiences personally with my truck. Every truck will be slightly different. I hope this helps someone with saving gas. Good luck!

I can sometimes drive at 120km/h in ECO mode. Obviously not up hills or anything but on the right road you can do it for awhile.

Dont remember reading anything about people driving that speed in ECO mode? Or if they have expermiented with the mileage. It must be better to run on 4 cylinders at 120 then 4 at 100??

From what Ive found you cant go more then 125km/h in ECO mode it will automatically kick you out of it.

I tested out the eco light once and found that it came on even at 90 mph (145kph) when I let off the gas. From what I understand it will come on when the motor is not under any load. My guess is that the wind resistance at the higher speed puts too much force on the truck for the eco light to stay on.

On my guages I go to the fuel economy screen and watch where the MPG bar is. I try to keep it all the way to the right (30MPGs)

The eco light is just a glorified vacuum gauge.

I've been keeping my cruise control at 64 or 65mph for the last few weeks and have found that my gas mileage has improved. When I was cruising at 70 I was staying around 17-18mpg, now that i stay around 65 I getting around 18-20mpg.

I'm at about 12mpg city and over 20mpg hwy. Crew Cab 4x4 w/3.92's. These Hemi's really suck a lot of fuel getting up to speed from a stop, in a city that likes installing stop lights not so good, lol. I have read that mileage improves with a few miles on the clock. I'm at 7500km (4500 miles) so we'll see.

I was told 87 Octane which is what I've been running, will 89 improve mileage?

89 octane may very slightly improve mpg. It won't be huge though if it does.
