Well, I keep the crossbars on the rack, I have a 2" Anderson Fabrication lift kit, I switched tires to a more aggressive Champiro Ice Pro tire and I average 70mph highway driving which includes about 10% city, 5% mountain and 85% highway driving. That being said I'm averaging 28.8mpg (actual). With all season tires I average 29.4 (actual). Not complaining at all with those figures.
Nope that all makes sense.

I plan on picking up a Crosstrek this summer. I have a 30 mile each way commute (90 % freeway). Plan on having bars and the 2 inch lift. So seeing/hearing real world numbers is always nice.

My STi, on the stock motor and driving as easy as I could, would get 24 MPG - spending $100 a week on gas. So I bought an older civic just as a DD. 35-40 mpg depending on how I drove and $25 a week in gas. I think ill be selling the civc to get the Xtrek.
 
To begin with, I'm at 607,189 miles right now. The Crawford system has had no discernable effect on oil consumption either way. Oil consumption is increasing slightly but it has been regular and I do have a few miles on this engine.
I do have one concern/annoyance. The standard Subaru 5th gear whine is becoming a little more annoying. Considering I spend 80% of my time in 5th gear it's not surprising. I think next time I do a clutch job, just for fun, I'm going to drop the tranny and split the case. The tranny is working great but I'll probably just have a complete bearing/seal set on hand anyway.
Outstanding.

How much consumption have you been having? How often have you been needing to replace the clutch?
 
I know those numbers are slightly ridiculous. September was 20,000 miles and October was 22,000 miles. Over the last 6 months I average 1 quart every 5,000 miles but I've been running pretty hard. The clutch always looks great, it's the clutch bearing that begins to whine around 150,000 and needs to be replaced around 160,000 to 175,000 miles.
well 2 extra qts on your 12k mile oil changes doesnt seem too bad hah.

Bummer the Crawford didnt help at all.

Are you replacing the bearings with OEM or aftermarket?
