coasting only helps if you are not dropping your average speed. slow acceleration does more than coasting to help get more mpg. an excepting is light timing.....big way to decrease fuel consumption. steady average speed wins the day. another exception, on the upside of a hill, if you keep your speed steadied or up, your fuel mileage will go down. which means if you coast down the hill and power up the other side you didn't gain overall increase in mileage. you will get better mileage to add a little speed going down(easy for the engine) a hill and let the car slowly let the car reduce speed up hill(again easy on the engine). anytime......i repeat....anytime you mash the gas you are not going to better mileage.
seems like we missed the point on miles per gallon...... which is how much it cost to make the vehicle move. if premium does it for you, use premium. most cars set up for or recommended to use regular are cheaper to operate that way.
i never fooled my cars gauges...they were off a little but still indicated near correct overall averages.
for my efforts, i never...never, saw any difference is premium fuel. my differences shown themselves in ambient temperatures. hotter the day, better the mileage. speeds at 62 or below also showed up differences. anything over 62 and mileage went down...across the board.
warming up your car.....eats your fuel economy up. you want fuel mileage, be ready in your car and when you start it, go. you can gain a tenth or so if you back in each night before you start. takes at least 4 minutes to reach operating temp. cheaper to back in when the car is at operating temp than not.
the 1.8 engines could never match the 1.4 turbo's for fuel mileage given the same driver and route. same with auto and stick. the shift points for the auto were noticeable higher than recommended the stick.
if you don't have flat roads, you will not get the mileage of those who do.
