Before everyone blows a gasket and over analyzes everything let me explain. Since I purchased the Z I have closely monitor the mpg and engine noise. I know that there is some variance between the "actual" mpg and the computer calculation. Since all measurements have been consistantly on the computer I feel that this is pretty reliable. Also, calculations were based on numbers after break in period.


I have taken several road trips in almost exact conditions. Temp, Humidity, altitiude, mph etc.... Also I have calculated the city driving versus highway driving.

After the K & N drop in filter I had the following results.

1. Less restricted air flow. Sounds like it opened the engine up and it breathes easier. A little throatier too. ***note that I live at 5700 ft.

2. Gas mileage increased from 20.9 to 22.8.


just thought I'd share.

 

Interesting... Ive been wondering if Im the only guy getting 20.x MPG all the time in this 21-26 MPG car. my AVG speed is 38 MPH and I usually see 20.8 MPG.

38?

 

I get 26 - 27 MPG in mixed driving and I'm just getting broken in (1500mi). Base 6MT. I normally shift before 4K RPM and run in 6th alot. You should be getting better than 21.

 

You must be driving it like an old man! Use the accelerator for chrissakes!

 

For reals, I get on average 24mpg and thats about 90% freeway miles.
