Gaining 2.15% at 10 MPG means you moved up to 10.215 MPG, a savings of

the data for the wheelcovers are here


(Results Of the Wheel Covers (Pizza Pans) Tests! :

Today we have tested the wheel covers to prove their efficacity and their FE with an A-B-A test.

Here are the Results :
11°C (51,8°F) / Speed : 50 MPH (80 Km/H) / 06 October 2011 / Good Conditions in general.

A = With the Wheel Smooth Covers (Pizza Pans)
B = Without the Wheel Smooth Covers (Pizza Pans)

In MPG (US) :
|-------|--A---|--B---|--A---|
Run # 1 |-61.2-|-59.5-|-62.4-|
|-------|---------------------|
Run # 2 |-57.2-|-57.1-|-57.6-|
|-------|---------------------|

Results :

Run # 1 Combined A = 61.8 MPG (US) (3.81 L/100Km)
Run # 1 Result of B = 59.5 MPG (US) (3.95 L/100Km)
Run # 2 Combined A = 57.4 MPG (US) (4.1 L/100Km)
Run # 2 Result of B = 57.1 MPG (US) (4.12 L/100Km)

Difference of 2.3 MPG (US) With the Run # 1.
Difference of 0.3 MPG (US) With the Run # 2

Final Result of the Testing of the Wheel Covers (Pizza Pans) :
