Does driving on Highway save gas?
The Daily Drive Slow down and drive the speed limit. On the highway, aerodynamic drag causes fuel economy to drop off significantly as speeds increase above 50 mph. Avoid “jackrabbit” starts and hard acceleration. These actions greatly increase fuel consumption.
Does idling use more gas?
Idling wastes fuel – and money. Vehicles get ZERO miles-per-gallon while idling. Larger vehicles tend to waste more fuel than smaller ones. Idling can also cause greater engine wear-and-tear over time, resulting in higher maintenance costs.

Does premium gas give better mileage?
