Advantages of a stroker for daily driver

no, a 10:1 comp ratio gets better mileage than a 8:1... if all other factors are the same.

it burns the gas more efficiently, gets more power out of the same amount of fuel.

to keep the mileage good
- 3:23's for highway
- keep the weight of the car down. more weight = lower mileage. dont go to extremes however. so aluminum heads/intake can probably save you close to 100 pounds.
- a manual trans setup will get better mileage than an auto... since you wont be running a "lock-up" converter like a lot of new cars and trucks use, you will lose 5-10% with a non lock-up torque converter. that's just a fact of auto trans life
- how you drive affects your mileage. on the highway keep a long distance between the car in front... it's safer so you dont get rear ended or have to slam the brakes and slide into another lane or into the car in front... but it helps mileage because every time you have to use the brakes to slow down you are wasting the fuel you used to get up to speed. so keeping a good distance and only using the brakes occasionally is best practice
- keep it tuned up - plugs and air filter in good shape, timing set right
