What is the highest indicated mileage you guys have seen on the GLE 43 Coupe ? I know my car seems to be a bit optimistic on the indicated MPG.
I was on an evening drive in the suburbs with the wife, low traffic, temps low 70s, flat roads. Saw that I was getting pretty good mileage on the way out, so decided on the way home to see how high I could get the mileage on a 1 hour round trip drive.
Wife said try to drive 55 mpg on a short highway stretch. It was really hard, but I drove in the right hand lane at 55 mph for almost 3 mile highway stretch! Trucks were passing us.
Really surprised when I got home to see 25 MPG indicated for the entire 1 hr trip ! 23 MPG was previously the highest mileage I have ever seen indicated on my car. The surprising part was I took the scenic route on the way out, otherwise might have even been over 25 MPG. Also was running the large 22" wheels.
LOL! I've been in the "indicated" MPG of higher than that, right after a fill up. We live in a small town, and the next closest town is on a 55MPH road. After filling up, AND driving 55MPH, I've been higher than that.
However, be prepared. Be very prepared, because it doesn't last.
I have a fuelly.com account, and I keep very accurate records on our fill ups. Our overall average over 21K miles is 17.8MPG, with our BEST being 19.9MPG. I've also noticed that we are generally about 1.5 MPG higher on the indicated than we are on the actual.
I just went back and further analyzed my data, and I was pleasantly surprised. We are closer than my gut told me were.
Over 55 fill ups, we have averaged 1.06 MPG indicated vs. actual, with the indicated always being higher, except for the first tank. I'm calling that one a fluke.
The max that we've been off indicated vs. actual was 2.11 MPG, and the min was .22 MPG.
In the end, for us, I think that it's safe to say that we're off about 1 MPG indicated vs. actual.
I'm actually surprised that it's this far off. Our first MB was an E320 CDI. That car was just about spot on indicated vs. actual almost every time. Back then, I wasn't keeping the records, so I don't know that for sure, but I do know that it was generally "closer" than the GLE is...
As another trivia point, for the last 35 fill ups, I've been tracking the average indicated speed as well during that fill up. The average speed per tank has been about 41 MPH. The highest that we've been is 56. We do a lot of mixed driving. We live in the country, so it's 3 miles to town, and then town driving, so the 40 average seems about right...
Cadman, jealous of that 41 mph average. Around the city of Chicago and suburbs where I drive, I am lucky to get into the mid-20s avg mph. Over the 8000 miles on my car, however, I have averaged 31 mph, but that is because almost 1/3 of my miles were accumulated on a long 2500 mile road trip at highway speeds.
One odd thing about your 41 mph avg is your average fuel economy is only 17.8 mpg. Mine is 19.9 mpg (indicated, not calculated) at a lower 31 mph average. Even if my indicated mpg is optimistic by 1.5 mpg, I would still be at 18.4 mpg. Seems if I could be at 41 mph, my mpg would be much higher than 17.8 mpg. BTW, steady driving at 45 mph seems to be the best mpg for my car.
Also, kuddos for your great work on fuelly, impressed with your meticulous record keeping! I snap a photo of my odometer mileage and the gallons indicated on the fuel pump every fill up, but have not gotten around to calculating any actual mpg. You are motivating me to do it!

THANKS!!
Yeah, I have found that I have to put those values in at the time of fill-up or they get lost. I do occasionally put the receipt in the car, and then fill it out later, but I have to still remember. I think that I've still missed two on the Benz. On our last vehicle, which we owned for years, I probably missed less than 15 over the life of the vehicle...

My last car was a Lincoln MKZ hybrid.I made a game of using all the gas saving driving techniques to see how high I could get my MPG readings.Like coasting up to stops,feather starts,doing the speed limit.Most of my driving is highway.In the MKZ,I beat the sticker-listed MPG estimates.
Still use the same gas-saving habits with my GLE 43 coupe.
I had forgotten that I had used the car for hauling full loads of equipment when my relative moved his office upstate.That did drop my total mpg down.Here is a reading for the past1800 miles----22.4mpg.

WOW! That is impressive for sure!! I don't think that I've gotten that good when I've driven 55MPH for long periods of time...

I am really having trouble getting my head around averaging 22.4 mpg. Even if you do only highway driving and your avg mpg reading is overly optimistic, it still does not seem possible to me.
I often pull away from lights slowly, upshift early (under 2000 rpm), coast to red lights, etc. and most of my miles have been on a long highway road trip. Still, only 19.9 MPG average over the last 7700 miles (22 mpg hwy, city driving mpg is more like 13 mpg).
What are your sorcerer tricks to achieve this MPG (or do you use another car for low MPG drives)?

Over 2000 miles, averaging over 22 MPG is definitely hard to get your head wrapped around. I've seen 25+ over about an hour, after refilling, BUT that only comes when you're doing SLOW highway speeds like 55 MPH on lesser 2-lane roads.

In the end, I think that one of the biggest gains to be made on MPG is DOING THE SPEED LIMIT, OR doing less than the speed limit. Kansas is 75, and it's hard not to drive at least 75 when you're on the Interstate. At 75 MPH, you won't get any good mileage...
slow starts
coast to red lights
usually only me in car so except for the moving event,not hauling much weight
Stick to the speed limit
Use cruise-control whenever possible
listen to Burl Ives music

Not sure how much the last one effected my mileage
