Flex Fuel E-85
If so, what was your mileage difference or any performance change?
Thanks.
Where is it stated? Is the GLK 350 included?

Scroll down, below the Hydrogen fuel commercial, there you will see the banner for E-85 available for C E and M classes.
Also on the MB website spec page for the ML350:
Engine, Drivetrain, and Performance
Engine
Net power 302 hp @ 6,500 rpm
Fuel tank capacity 24.6 gallons
Net torque 273 lb-ft @ 3,500 - 5,250 rpm
Compression ratio 12 (Wow!!
)Construction
Diecast alloy block and alloy heads
Fuel requirement
E85/Premium unleaded (FFV option), or
Premium unleaded
Fuel economy
City fuel economy 17
18 (FFV option)
Highway fuel economy 22
23 (FFV option)
So they are advertising that it gives BETTER mileage with E-85?? Never found this to be true in the real world, but also never driven a GDI ML350.

Like I said the guy above who put E-85 in his HHR is will be fine.
Obviously M-B wants to keep the FFV (what is that?) Option a secret.
Also, M-B says you need a special optional engine to burn E85. Not the standard engine.

Which one has it right?
Usually when I see a FFV vehicle, there is a badge on it, like the domestic vehicles. I have seen this sticker on the inside of the fuel lid on a loaner C class last year.
Any tech's out there that can shed some light on this?
I know that Flex Fuel Vehicles need special lines and a calibration to the computer, but is this a case where MB just didn't label the vehicles and used a reprint of last years manual? Or the web site is "ahead of itself"
Can anyone say if the emissions sticker under the hood advises FFV capable?
Google around the Interweb. There are E-85 calculators that will give you a break even point based on fuel price differential and mpg. Today, in Houston, E-85 is $0.50 to $0.70 less than 93 octane premium. Find an online calculator. Do the math. Factor in the scarcity of E-85. I have 2 sources conveient to me in Houston. However, the supply is spotty-often none available. Beyond the city availability drops to zero. Unlike diesel which is available everywhere.
E-85 is the answer to a question that nobody asked.
By the way, apparenty M-B doesn't offer FFVs. Call MBUSA. Ask them.
