Default Breakout MPG out of nowhere?

Yesterday I got 255 miles on half a tank. Trip computer reads 31mpg average. It was primarily highway driving at 75-80mph and some city mixed in.

In the past I've been getting 270 miles on a FULL tank. No clue what happened overnight...this car turned into a Hybrid or something

This is typical and happens, in my experience THREE times during the life of an Audi at the three following milage intervals.

Note: these are "in the spirit of" miles. It may happen earlier or later, but typically in the vicinity of the following.

5,000
10,000
15-20,000


Another kinda cool thing is that the POWER improves @ about these milage intervals, too.

Could be that the tranny is adaptive?

Could be a number of factors for MPG to change overnight: outside temperature, tire pressure, etc... All things equal it's most likely the gas that you put in your car. Filling on 90/10 ethanol mix will cause a negative impact on MPG while filling on more pure gas mix will increase it. Even if you fill at the same gas station you may still be affected.

The 2.0T loves straight highway cruising. You can easily exceed the EPA numbers on the highway with that engine as long as its a steady 65-80mph.

I am ready to bet that cruising at 65mph with a manual will get you over 35mpg, perhaps even close to 40.

It'll be difficult in an A4, particularly quattro models due to weight. I did manage to push close to 34mpg in a DSG equipped Jetta GLI however.

During summer I got over 36 MPG by using cruise control at about 60 MPH. Trip computer is optimistic by about 1 MPG but still impressive. Of course using cruise control is no fun, I typically get between 26 and 30 MPG on the highway.

Two weeks ago I took a trip to Florida from South Carolina in my 2.0T Quattro. 90% of the travel was on I-95. I had it on cruise control for most of the time and I got a little over 34 MPG on the interstate part of the trip.
