poor fuel economy

[dimstamat]

Hi everyone,

I recently posted about poor fuel economy on my 2009 A4 2.0T quattro automatic. I got several advices, but still I'm getting around 300 miles per tank (around 18mpg) when driving 70% highway, 30% city. I recently had the 75k service which replaces spark plugs and many other things, but fuel economy did not improve after that.
Do you think the wheel alignment has to do with fuel economy? When I go above 65 and turn slightly left, wheel is shaking a bit.
Thanks!

What mileage were you getting before? What engine oil do you run? Have you changed it recently?

Wow that is low for MPG! The 75k probably did the oil, but good to check. Did you check the air filter? Also did you have (or do you have) oil consumption issues? Just a shot in the dark, but maybe your intake or catalytic converter is clogged with carbon buildup.
