What I do in addition to driving method.
Better Low roll resistance tires?
Yes, Goodyear Assurance Fuel Max tires.
Highest psi for tires
Not quite. My tire max at 50 cold psi, which makes the ride horrible. I run about 44 psi.
Air induction cleaning, fuel treatment cleaner
There are enough detergents in todays gas that I do not feel the need to treat my fuel.
Does the rear wing help or hurt mpg?
Prolly hurt, but not enough to make a difference imho
Under car aero mods (might be dificult)
In the works. I am waiting to see what they do with the Eco Cruze...
Synthetic oil/ lower viscosity 0-20?
Mobil 1 fully synthetic 5w30
K&N drop in filter. I got a good deal on it, and it will save money in filters over time. It's not all about mpg afterall.
Prolly will not spend money on this. I do not see where it will help enough to be worth the investment.
Bigger tires for lower rpms at speed?
This is a possibility after my current tires wear out.
