Stock 2000 WS6 A4, averaging 20.5 with same route.
I would think anything in the 16-18 mpg range for all city is normal. 14's seems way low to me?

These cars are so are-sensitive - we can judge urban city driving and highway speed driving. Anything in between is a crap shoot.
I've gotten the full range. 10mpg (stop every other block, driving amongst skyscrapers) and 29.5 mpg (highway at 55 mph, on flat roads, cleaned MAF, and new O2 sensors). When these cars were designed, the National speed limit was 55 mph, so it shouldn't be a surprise that we see the best mpg at that speed.
So, when you are 40+, you'll also get odd results. There's goodness up to 55, but then the mpg's drop off radically as we push to 65+.

Some more perspective:
If you subscribe to the school of thought that the fourth gen is really a minor evolution of the third gen body, then these cars were actually designed before internet browsers existed. At the time, the wheel was a modern wonder of science and man marveled at his ability to tame fire.

I'll tell you what will kill the mileage on these engines is dirty lifters. I Have owned 6 LS1 fbodies THEY ALL averaged 24 combined city-highway driving. all highway driving 29 all city 20. But 2 of them had lifters troubles when I 1st bought them and both those cars had terrible fuel mileage until the lifters were cleaned-repaired. After that they both got great mileage.
Even driving like a mad man I never got less than 20 when I filled up.
but considering your short trip times I'd say its about right. Drivetrain is barely getting completely warmed up. Takes about 18 miles driving to get everything up to temp.

I was getting 19MPG/avg on my 1999 M6 SS with full boltons, and have consistently gotten 15MPG/avg on my 2000 M6 SS (Forged 402 with 600+horsepower) this is daily driving and driving each vehicle in the same matter so your numbers seem pretty concerning for a stock vehicle. Previous posts in this thread seem to have helped out but I just wanted to give you a comparison/personal experience for my situation.

I have 02 extensions due to my LT headers.......
2344617 are 44" long........way way long....you will have to wrap and fold the excess wire, but that's cool.

Yeah it is very strange. And I have also heard the fuel gauges aren't accurate in these cars BUT when i leave the car in the morning then come back in the afternoon to leave and start it, it looks like the fuel has dropped slightly. Today for example, i parked with the meter perfectly on the "F" line, but 8 hours later, it was below the line instead of touching being lined up perfectly.

The gauges definitely aren't very accurate, they are more of a dummy gauge to give you an estimate on your tank level. I would never attempt to measure the actual MPG based on your fuel gauge. I just reset my trip odometer when I fill up, and write down how many Liters (Canada) I put in the car.
The fuel gauge will do odd things. There is a float in the tank but the tank is not a regular geometric volume. It's an odd shape, so as the level goes down for any given inch inside the tank, there will be a different volume of gas expended.
So, I've observed that the needle runs faster to empty for the last half of the gauge readings than the first half.
