I got 25.4 mpg on my last long trip. Really great mileage from a V-8, in my opinion.
By the way, did your '08 have a gas guzzler tax? If so, how much? There has been some debate on this forum about this. You can solve the mystery for us.

Sorry if this has been answered before but does anyone know if you can adjust this feature with STAR or other method in attempts to make it more accurate? Side note, I have stock 17's and tires but have the RENNtech ELM on position 3 (about a 1 1/2 drop) if it matters.

I just returned from a 6,100 mile vacation in my new '08 E350. The computer said I got 26.8 MPG for the entire trip. This is for a wide variety of driving conditions including altitudes of over 8,000 feet, temps of over 100 degrees, freeway and urban driving and a lot of cruise control even in hilly country.
With my previous '04 E320 I took several very long trips in it that were similar to the trip in the E350 and those trips resulted in the computer showing as much as 28 MPG for a trip.
On that car, I compared actual mileage vs. computer mileage and found the computer to be about 1 MPG optimistic. I assume the E350's computer is also somewhat optimistic.
If I were driving an E550 on my most recent trip, I'd be surprised to get much over 24 MPG. Even so, the new Mercedes engines w/7G transmissions are as good as you're going to get.
Like any mileage measurement, you must average several tanks of fuel to know what you're getting. The computer is somewhat accurate but not perfect.

If I'm reading the right number, I’m getting about 23.2 on my 350.
And, I haven’t driven it hard.

RE: Mileage
On a recent 300 mile trip from North Carolina to Maryland, my 05 E500 registered 29.3 MPG. I had a full car, 4 people, and a trunk full of luggage, a/c on.
On the return 300 mile trip, my new 07 E550 registered 27.4, I was however gentle with throttle, had the transmission in "comfort" mode, and kept speeds under 75 due to break in.
Assuming these indicated numbers are accurate, both cars are quite economical for what they are. I think the 500 will prove to have been a little
less thirsty vs. the 550.
Congrats on the new ride!

The gas guzzler tax is $1300 for an 08 E550
It is $1700 for an 08 E550 4Matic.
I'm not sure how anyone got away with not paying it, but thats what its supposed to be.

I hope you can avoid the gas guzzler. I can tell you that it was nowhere on the sticker or invoice and I confirmed with the dealer that it has 'gone away' for the '08's.
Good luck.

8-10 mpg in the city.... and maybe 21 in typical leaving town and trip traffic.... I think that you need to note the AVG speed during those high mileage runs.. my typical is only 45 mph with the mix.

Yeah, those two extra cylinders in the engine bay are probably just old soup cans painted to match the other 6.
And I guess some dude from the service department used a bic pen to perforate my seats then stuck one of those battery-powered fans from a baseball hat under the seat.
Egads! I've been duped! The bastages!

Hrm, was yours a very early 08? Because it might be using the 07 VIN series, which maybe exempted you from the gas guzzler tax?
Which dealership?

The best I've gotten so far on my '07 E550 is about 22 mpg. And that was mostly freeway. Other than that, I'm averaging about 17 mpg. I have a lead foot.
The car I traded in was a Lexus IS350 and I was getting about 20 mpg on average. So I'm not too disappointed with the mpg, since the trade-off is lear jet-like acceleration!

No Gas Guzzler Tax!
According to the "Build Yor Own" feature on the MB USA web site there is no gas guzzler tax on the '08 E550. My '07 had a $1300 gas guzzler tax. I don't know whether the car has changed, or the method of determining the tax.

On my E320 CDI, the fuel economy computer is actually low by 2-3mpg when compared to calculating fuel usage the old fashioned way. Others have complained that the economy computer can be very inaccurate (+/- 10%). My old BMW overstated by 15%! I think its safe to assume these things aren't very accurate.

Yes, the MBUSA site shows $0, but I've confirmed with a couple of dealers and seen the sticker on 2 08 E550's now, and its there .. $1300 or $1700 for 4Matic.

The SOHC 3 Valve engines were very efficient. The fuel economy of the 5.5L V8's is very impressive though.
How do the 5.5L DOHC 32V engines compare with a 5.4L SOHC 24V V8's in terms of fuel economy?

No GGT on the MY08 E550W
I can confirm there is no GGT on the MY08 E550W. For MY07, it was 1300. I understand there were software changes made which helped on fuel economy. For the MY08 E550 4matic, it is 1700.
