Default A4 Low MPG

Hi All,

New owner of a CPO A4 2.0T QUATTRO. Just over 6k miles on it when purchased and I have driven about 800. Noticed that after first 3 tanks or so I am averaging only 19-20 mpg (280-310 per tank) in 50/50 city/highway driving. This seems low to me. I drove a diesel Passat prior and averaged about 35-36ish over the course of a year (just mentioning to show city vs. highway). I am a bit worried. I have heard/read that after 1-2k miles of driving that it will improve/adjust to driving habits, etc. Not sure how true that is?? I've checked my tire pressure and all is good. Don't know a ton about cars ESP the technical specs. First time owning an Audi. Any thoughts/experiences/opinions/help would be greatly appreciated. Thanks!!

what gas are you using? it needs high octane to get best mileage, which should average either side of 28 mpg

You certainly won't get anywhere near the mileage of the Passat TDI. I had a 2009 A4 and IIRC averaged low 20mpgs with 65% hwy/ 35% city. What year is your A4? The earlier B8's with the 7 speed transmissions (2009-2010 I believe) got slightly lower mileage than the later ones with 8 speed transmissions. Check out stats from fuelly - avg seems to be around 24 mpg:

By comparison, my A6 TDI consistently gets 30-32 mpg (measured by the tankful).

Gasoline = 93.

And it is a 2014. Hoping the more miles I drive the better fuel economy I will see.

That's unusually low for a 2.0.

I get 290 - 300 miles on a tank of gas on my V8 S5 for city driving and 360-370 miles for highway. And this is on a V8.

My 2013 Audi allroad achieved 30 - 32 on the highway once I crossed the 9000 mile range on my Odometer. This is the same 2.0 turbo engine you have. You should achieve at least 28-29 on the highway. I average 25 MPG for city driving on my allroad.

I thought the same as far as it being unusually low. Checked my tire psi and everything was all good there. I'm going to give it a couple thousand miles and see if it increases before I take it in.
