If so, that explains it.
Oxygenated gas will kill, on average, 5% - 10% of your mileage.
The oxygenated additive displaces gasoline, so it takes more of this crap to power the engine.
Oxygenated gas is a @#%*(_%_ conspiracy.

Non-turbo FC's should easily do 15mpg.
Mix in some highway / freeway driving, and it should start to head towards 20mpg.
Start doing some serious freeway driving, and you can easily break 20mpg and start heading towards 25mpg.

At best mileage driving conditions, it'll get close to 30mpg...
To do this, do all your driving in top gear and at 3,500RPM - the key is the RPM's, cause you want to keep it right under the secondary fuel injector crossover point.

Yes, we don't have real pure gas here, fucking tards.

Also this makes complete sense. 3500rpms in 5th gear is quite quick, too quick for being legal around here (fucking 65 max state limit). I may end up trying to see if I can break 20 this summer. Before the cold set in, I was getting 16 pretty easily, and defiantly not taking it easy.

So, my car "should" be in good operating order based on fuel usage. I just need to:
1) stay out of the city all together
2) run real gasoline (fuck this shitty winter mix)
3) stay in a warm area
4) drive faster, but stay in the primary injector range.
