If you are going to change oil every 3,500 to 5,000 miles, then IMO,
synthetic is not worth the extra money. I've seen many engines with over
300,000 miles that were routinely serviced with conventional oil.

Some European makes use trip computers that calculate when to change the
oil. Toyota uses "conventional wisdom" in the U.S.

There are a lot of factors that affect fuel economy, but oil changes are not
usually one of them unless the engine is filled with the wrong oil or the
oil hasn't been changed and the engine is sludged up.
Factors that affect fuel economy:
Weather
Traffic
Driving style
Tire inflation
Brakes dragging
State of engine tune
Transmission condition
Fuel
