20 Ways To Get Better Gas Mileage
Three eco-driving techniques to increase gas mileage is to go easy on the gas pedal; avoid unnecessary idling, which means if you're not moving anywhere for more than a minute, turn off your engine; don't speed, and drive at or below the speed limit at all times.
Premium gives better gas mileage
Because premium gas has a higher octane rating than midgrade or regular gas, it produces a little more power when burnt. Designed for performance cars with large, powerful engines, premium also helps minimize the risk of preignition inside highly-stressed, hot engine cylinders.
Going slower technically saves fuel because at high speed your engine needs to work harder to overcome drag from wind resistance, your tyres and transmission, and that drag increases exponentially the faster you go. Reduce your speed, then less power (and thus fuel) needs to be expended to overcome that drag.
