TrueCar compiled a list of Apps to keep fuel costs down. Here are a few that are free or cheap:
iGasUp — Pricing info on 110,000 gas stations based on credit card transactions. You’ll find out the 10 cheapest stations nearest your location once the App is launched. Cost: 99 cents.
Waze — From other user’s input from the road, the App tells you how to avoid traffic snarls. That prevents burning up gas sitting in traffic. Free.
Meanwhile the Alliance to Save Energy issued these tips to save on gas:
-- Make sure tires are properly inflated and improve mileage by up to 3.3 percent.
-- Follow the car makers' recommendation on the grade of motor oil. Wrong oil can reduce gas mileage by up to 2 percent.
-- Empty the trunk. Extra weight reduces mileage. Same goes for the roof. Avoid piling stuff on the roof rack that can lower your fuel economy by as much as 5 percent.
-- Slow down, avoid idling and use cruise control.
