keep the revs to around 2000-2200, no hard acceleration or high speeds up
through the gears.

keep tyres at the correct pressure.............

reduce air con/climate control running..............

Well, that's a little below the EPA estimates of 18/25, but, of
course, that's the old estimate that doesn't reflect real-world
driving like using the climate control, headlights, etc. Any codes
stored in the car? You can get that checked at Autozone for free.
Might not be a bad idea to make sure there is nothing going on that
might not be generating a CEL. I'm not sure how the computer
calculates the mileage but the old 'divide the elapsed mileage by the
number of gallons' is the best way to calculate it. My computer seems
to read a little high.

In my car I have averaged 22.78 mpg since new, 80% around-town
driving.

When was the last time your sparkplugs and engine air filter were
replaced? If it's been a while, you may want to replace them. 18 mpg
seems a little low, but then again, it depends on how fast you drive.

Check the owner's manaul or the gas tank fill door to confirm the 2.7T
needs a minimum of 91 Octane fuel. Being a twin turbo engine with knock
sensors, filling up with a lower grade fuel will definitely reduce gas
mileage and performance. Lower octane fuels also increase risk of
clogging up the fuel system as well as increasing emmissions which is
harder on O2 sensors, EGT sensors and all four of the the expensive
catalytic convertors.

What is the vehicle odometer mileage?

Recommend a VAG scan to see if there are O2 sensor or EGT sensor codes.
Failing O2's and EGT Sensors will reduce gas mileage. I replaced both
front O2's at 80K KMs on 2.7T, they are primary feedback to ECU for auto
adjusting A/F mixture. VAG-COM supports tests that can be performed to
check responsiveness of O2s, they can become sluggish with age before
triggering DTCs and CELs.

I have a 2000 A6 2.7L twinturbo. I use 93 octane. My mileage is about
21-22 from a mix of local and highway travel. When I average just the
highway then the mileage seems higher ~25 and if it is local then it
falls to ~19. Once my average went to 17 or 18 even with enough
highway travel from 21. This went about few weeks and my car starting
shaking and I had to turn it in to a mechanic (decent one) and he
found lot of deposit on one of my valves. he opened up the engine,
replaced it and costed me a lot of money. I would recommend spark
plug change and engine cleaning to remove any deposits.

Are you saying all Audis sold in the US have to be modified in order to
run reliably here?

Are you aware of two different formulas used around the world to
calculate the octane number?

I assume "here" for you means the US? If so then yes. The fuel quality
in the US is much lower than in western Europe. The Audis (and VWs and
BMWs and Mercedes) that are made for the US contain specific
modifications to run reliable with that low fuel quality.

Anecdote time. Back in 1981, I was living in New York, and owned a Camaro.
I went to live in England, taking the Camaro with me. I expected the
numerical miles per gallon to increase by roughly 20%, since the imperial
gallon is 20% larger than the US gallon, and my driving mix was similar.
In fact, it actually increased by 44%. A year later, I went back to the
US, and the mpg dropped back to its former value.

Can you provide links to some documentation on this subject? It's not
that I don't trust you. It's just that I'd like to find a valid source
if this information.

Thanks,
Pete

In European Union, Iceland, Norway and Switzerland diesel fuel must meet
EN-590.
More here:
http://en.wikipedia.org/wiki/EN_590

I know for gas[oline], there is also such a norm, but have to look up
the EN number first.

My 2000 A6 2.7T generally gives in the low 20's when at highway speed
(~ 70). City driving in the upper teens. The nice thing about a
relatively small V6 is that it will do well with gas mileage at
cruising. The MPG depends on how much you engage the loud pedal
(turbos). The power is there when you need it (to pass, etc.) but a
large displacement engine is not being pumped when not needed. Your
mileage may vary..

You call low 20s good gas mileage at cruising? Maybe for a 5-liter V10
engine. Most modern V6 and I6 engines can do much better these days.

Don't get me wrong, I know this 2.7tt is not your ordinary V6 and it
lots of fun, but good gas mileage is not one of it's strong points.

VWs lack the high top gear that gives Japanese cars their good milage.
It makes them more responsive but it costs dearly in cruising efficiency.
