2.7T Gas Mileage
I am a recent owner of a 03 2.7T and am getting about 18 mpg. I am running
premium gas and most of the driving is highway. The computer claims I am getting an average of 21.6. Does this sound right? If not, what can I do to improve the mileage? Thanks, K |

I don't know the specifics of your car, but some of them can run on cheaper gas with no ill effect for light driving. Fill up with 87 or 89 (US grades) for weekday commuting then put in 91 or 92 for the weekend trip out of town. -- I don't read Google's spam. Reply with another service. |

If not, what can I do to >improve the mileage? >Thanks, K I live in New England, and have kept a mileage-tracking spreadsheet on all of our vehicles (for god only knows what reasons ;-) Over its life (I've owned it since brand spanking new), my S4 has averaged an actual 20.56 miles per gallon, while the computer-calculated mileage has indicated an average of 21.50 mpg. Not too bad an error rate (4.39%). All fuel used was at least 91 octane; and I'm guessing most of those miles were using 10% ethanol. The vast majority of my S4 mileage has been on the highway, usually cruising at around 85mph in top (6th) gear. Are you driving an A6 S-line, or ? I expect the 6er is heavier than my car, which might explain some of the difference... Cheers /daytripper '00 s4 6spd |

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. Dan D '04 A4 1.8Tq MT-6 Central NJ USA |

Does this sound right? If not, >what can I do to improve the mileage? 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. Pete |

2.7T Gas Mileage
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. -- K04-S4 ------------------------------------------------------------------------ K04-S4's Profile: http://www.audiforum.ca/member.php?userid=2727 View this thread: http://www.audiforum.ca/showthread.php?t=15724 |

Remember that these engines are developed with European ROZ95/98 in mind and have to be modified/limited (electronically and/or mechanically) to run somewhat reliable in countries that have inferior fuel quality standards than western Europe.

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 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. |
