I am averaging 17.5mpg in my wagon... so I drive however hard it is to get that

 

You guys didn't know? Subaru instally a hypdermic needle in the bottom left side of the driver's seat. It's ****** you initially as you sit so you don't know it happen. Then, in conjunction with the boost level, the ECM injects the driver with low dosages of adrenaline/stimulant, so as not to be noticeable... but the cumulative effects are quite obvious, as noted in this thread.

Why else do you think the dealer charges so much for simple things like oil changes or radiator flushes? IT'S BECAUSE THEY ARE SECRETELY TOPPING OFF THE ADRENALINE TANK LOCATED IN A HIDDEN COMPARTMENT NEAR THE PASSENGER FIREWALL OF THE ENGINE BAY. (Covered by sheet metal so you can't see it unless you are looking for it. You'll have to remove a rubber grommet.)
