#303 of 304 extra nitrogen in tires, total waste of $ !

just so you know.. there is no benefit to extra nitrogen in a cobalt tire or any passenger care tire, except for lining the wallet of whoever sells it. the idea of hydrogen in the tire is horrifying and reminds me of the JATO story legend ...
btw, measure distance-driven/gallons to see the real mpg and compare with dashboard mpg-meter... i bet you'll find the dashboard usually off by the same percentage and reading a tad high in your case.
I always liked cobalt styling! almost bought one but waited for cruze. :}
#304 of 304 smooth paint vs smooth wax finish for mpg (!)

i avoid waxing cars...
let's just say/suppose it's for mpg reasons: i figure the weight of the wax costs more mpg than the smoothness/airflow at such low speed.
but seriously folks, the clearcoat under the wax is just as smooth as a layer of wax on top of it, isn't it ?
for aircraft the weight of the paint really matters - iirc, some aeronautical painter discovered a way to use thinner layers of paint... added up to hundreds of pounds per aircraft... less weight, saves the airlines BIG $ on fuel.
