Well since i went wingless about a week or so ago, I've noticed that I'm getting at least 20 more miles on this tank. Anyone else have any experience like this? I was averaging a horrible 160-165, this tank i got at least 180 in. I have been driving the same, same gas and same weather.

Anyone else?

 

You wernt driving as aggressivly I think, but it could have something to do with it, less downforce at speed, less strain on the drivetrain, less resistance for the motor, equals better gas mileage?

 

if i drive cool i get 90 miles out of a qrt. tank.

 

Thats what im thinking. My driving habits were the same. Shifting at or under 3500. Only really hit boost 2 or 3 times. But i seem to be getting more mileage out of the car without a wing. About 50% of the driving is on the highway.

 

hmm..this is very interesting. It makes sense, but I didn't think the wing would make that much of a difference.

 

It is reasonable to assume that the small reduction in aerodynamic drag from removing the wing would have a slight effect on fuel economy. But I would expect the improvement in fuel economy to be approaching statistically insignificant levels, not the 10% improvement that you report seeing...

There must be other factors involved for you to see that kind of fuel economy improvement.

 

I'm going to guess that vehicle speed also plays a part. If you average a higher speed than others, your drag will cause a more drastic affect on your mpg. But my lord, you only get 160 with shifts at 3.5k? I drive pretty much identically to your style and get 220-230 with the winter blend.

 

Yea I don't know whats wrong with my car, gas mileage has been sucky lately, ever since it started getting real cold.

I also find it hard to believe that taking a wing off would cause that much of a jump in mpg.

 

^that's what I get all the time, and I run 93, still have my wing on.

 

See if it continues on your next few tanks. I am pretty sure you probably had more highway miles than usual.

 

180 mi doesnt seem that great either?? I think I average about 200 or better to a tank

 

+1

 

You also get only about 160-180 on a tank?
Might also be a front o2 sensor.

 

Seriously, my worst has been 180 and I only got <12 gallons when filling up after that 180 miles.

Usually I go 240-250 with normal driving

 

When I purchased the EVO I had now it had the OZ wing and I did notice better MPG. Somewhere in the range of 15-20 more miles per tank. Damn it costs a lot to have that EVO look.
