So I have a B6 A4 3.0 FWD which is actually really good on gas.

I also have a B6 A4 1.8t Quattrowhich is horrible on gas.

Why would it be that my 1.8 gets only about 200 miles per tank of gas compared to my 3.0 that easily passes 300 miles on a tank of gas? i drive both cars the same, not one harder than the other, and I drive them both to the same location (work). Anyone know?

Is there ANYTHING I can do to the 1.8t to get a little bit better gas milage? Both cars are pretty much stock besides a Forge DV and Carbonio Intake in the 1.8t.
