You made a valid point ^^^ I guess quality of fuel per car will make a difference to fuel economy. But that being said, I'm guessing that the vast majority here will run premium unleaded where possible.

Your numbers are looking good! A couple mpg here n there...no big deal I guess. But its nice to know that our powerful (very large!) N/A motors can return a reason mid/low 20mpg on the highway. ok around town it's not so great, but it's still not exactly in the low low teens like other cars (the E55K for example)

I remember several years ago (ok more like 10 years ago) there was a guy doing accelerated oil changes on his 2ZZ motor (every 4k) and running a snake-oil called Polydyn TX7 (a bit like Molyslip and all those other things). The guy was basically trying to do a real world long term test to see if stuff like this worked. He consistently drove in full granny mode for several months (gosh that must been dull) but eventually I remember him getting it to over 40mpg on average fuel fill ups, from being in the mid 30's (or low 30's...I can't remember). I wonder if anybody uses an oil coating additive on their M156. Probably not, but it would be interesting to see.

CeraTec and some other liquimoly additive are popular on here.

Ahhh, I didn't know this. Thanks man, I'll have a look into those for reference.

I only managed 20.5, with normal highway driving, although traffic conditions were as good as possible. This is the best I've seen so far.

BLKROKT

I use Boostane and Slick50 and get 53mpg now

Adi-Benz

BS I used it on my c300 and I only get 45

C SEXY 3

I regularly hit above this number on the highway, when going between LA and Bakersfield or San Fran, and on the flat *** 5.

xEryx

I run 91 or 93 and drive on E on the high way and I barely get AMG MPG, this is sad

Maybe the fact that I have disabled the transmission learning system/throttle lag/granny mode has a huge effect on MPG

Johnnie58

My car tuned (evolve) went from 26 mpg on hwy to 29 mpg after the tcu tune.

Id love better front seats , like audi rs4 not the **** ones ya yanks get . Wider rear end and tyre size .other than that shes the perfect modern day hot rod oh one more thing when the tc is off to be able to use cruise control or in sport mode that's fooking retarded

SuperFastYo

TC wont ever be able to be turned off while in Cruise Control. Hit a puddle, back end starts to slip and your Cruise control starts to full throttle to get your car back up to its cruising speed. No Good.

Johnnie58

Shame my audi rs6 could,

and the c63 cuts all telemintary too in this mode , fur me it's a PITA . Saftey third

SuperFastYo

I've never owned an Audi but I've been a brand ***** for awhile now and have owned a lot of different cars. So far I can't think of any that have allowed me to do that.

You should probably trade it in for a corolla or something similar to better suit your driving habits?

yellows2k

only thing i would have liked would be dab+
running wider tyres from oem and my car is pretty optioned out. air cooled seats would be nice, e class have them, maybe a bit of trickle down economics

Bringing this back for my new personal MPG record

For this to happen, I drove for 30 min 50 MPH, because some people who were visiting could not get the destination into their navigation and I had to drive slow enough for them to follow me.
I happen to look at the menu and my jaw dropped.
And it went to 22.8 before I stopped.
I didn't think this was even possible.
I was hoping that with this engine, the economy speed was around 80 or so, but it seems it's 55.
Just like Chrisriderbike, my "from Start" was over 23 MPG.

roadkillrob

You guys should all be embarrassed driving your car to get good fuel economy - I personally have never seen over 17mpg, getting good fuel economy and wearing out the rear tires just don't mix.

Jasonoff

My last fill up was 13.9 mpg

Yuille36

My biggest complaint was for the price we all paid for our C63, why didn't it have an alcantara headliner.

AMG3.2

You know Alcantara is actually a really cheap material? Fun fact that I didn't know either.

Yuille36

Yes, I'm aware that its a man made synthetic version of suede. I also have it in my E63 and I love it.
It add a nice quality look to any car interior. But it would be an upgrade to what we have as a headliner now.
