hahaha the wing has unnoticeable effect on mpg, maybe very very little haha

 

I get 280-300 a tank and I have a wing lol

 

Last week I got 162 miles on 12.7 gallons!
And this is shifting at 3.5k rpms and only hitting full boost about 2-3 times!

 

The wing does cause drag, so an improvement is expected. I think in other threads it was determined that it is worth a a mph or two at the drag sstrip. I think I get about 220 miles to a tank with my wing.

And that's all I'll ever get, because it ain't comin' off.

 

No way that has to do with your mileage. The wing creates downforce probably over 80mph and is very aerodynamic otherwise. Unless you are constantly driving 100mph, I really doubt the tiny surface area would cause that much resistance.

 

Lol, I get about this also with 100% city driving. If I do really any highway worth noting I get 330-ish to a tank.

 

I get about 235 a fill up with getting on it a few times. You must do mostly city driving?

 

I might have to try changing the front o2 sensor, that might be whats bringing my gas mileage so far down.

 

So you get 360 miles out of a tank ok.....

Have you had your car tuned at all, if so you may be pulling timing and flooding your motor with fuel, or possibly a boost leak to mess it up even more. JUst a couple thoughts, I always get 200 + miles per tank, but I did get poor like you and found out I had a few small issues.

 

interesting.. but i dont think it is the wing.. just maybe the way you are driving or maybe the weather strain on the car aka hot or cold temps

 

+1 I usually get atleast 250. 160 to a tank seems pretty low.

 

I am with you, I usually get 280ish if I just drive normal(which is getting on it once a day or so) When I am on trips or just doing highway driving, I get 300+.

 

Car has never been tuned. It only has a TBE.

 

actually I did a science project on this and yes without the wing does give you a 15 to 20 miles more per tank.
