ok aired up tires to 44 psi - rolling resistance lowered

also, got darkest legal tint for first ecomod
This will help with FE in summer as it will cut down on amount of AC useage

next, remove mud guards - aero mod


grill blocks for the lower section - aero mod

suction cup Kamm back - aero mod

rear belly pan attached to hitch - aero mod

it is a sedan with auto transmission

MPG has been under epa even with very conservative driving

However, for highway miles I do my share of passing...so that might be a reason

Best MPG is HWY 34.7 after 44psi tires.
prior to that it was 34 but just barely...

Best city is 32, worst was 27.8mpg

I just completed my coroplast grill blocks held on with zip ties.

I will have a few long trips where I can test this out later this week.

Trying to crack 40 MPG...but have not had my first oil change yet

I am expecting the mpg to rise as the engine settles in.

BTW - all the gas around here has up to 10% ethanol so I have heard this can hurt mpg as much as 25%?

Mileage usually gets better after the engine "break-in" period too.
