im no scientist but Ive reported this on the same stretch of freeway:

2010 LGT Stock:

Cruise control @ 65 mph for 10 miles = 32mpg

2010 LGT with my Q300 added on:

Cruise control @ 65 mph for 10 miles =36 mpg

Unfortunatly for the city its now a solid 18.7 down from 20ish

But this is most likely due to my new leadfoot habit and my desire to hear some nice boxer rumble and see the numbers fly...haha!
