A tank of gas is how much today? How to make the most of it...

If you can afford to fill your tank this week, get more mileage out of that gas with these tips from Popular Mechanics:



• A warm engine is more effective: String errands together by driving to the farthest destination first, which will get the block heated up, and then working your way home.

• Notice to hoarders: You don't need to lug around a case of oil, a bag of sand, or any other heavy stuff. Empty the trunk - less weight, better mileage.

• Avoid gas rated E15: The E is for ethanol, which has about 30 percent less energy than gasoline and kills mpg.

• Avoid traffic pinch points when you can: Driving at speed is more fuel efficient than creeping along in low gear.

• Anticipate traffic lights: Don’t come to a complete stop, you can improve fuel efficiency by as much as 50 per cent.
