It encouraged us to visit Quora. com, the online question and answer community, to find out how users get the most out of every tank of gas.
Light makes right
Alex Elderfield noted that excess weight prevents an engine from burning fuel efficiently. "Only carry what is essential in your car, clean out any junk or necessary items otherwise you are paying for the fuel to cart these from place to place," he wrote.
Driving smoothly — that is, not mashing the gas and then slamming the brakes later down the road — was a fixture of many responses. Quora user Clint Law agreed on that advice, who wrote, "Every little bit of kinetic energy that your brakes lose, your engine burned in fuel to build up." Overbraking should consequently be viewed as wasted acceleration. "That's really what kills your fuel economy," he argued.
Keep the pressure up
Keeping the recommended tire pressure for your car was another mantra among Quora users. Marlyn Rosent said she checked her tire pressure every time she filled up her SUV. Quora user Doug Dingus checks his tire pressure every weekend. “Less tire contact means reduced rubbing, requiring less fuel,” he said.
Air conditioning or windows
Though the summer heat get many drivers to roll up the windows and turn on the air conditioning, some people argued that running the A/C wastes too much gas. In between were many shades of grey.
Achilleas Vortselas said it would depend largely on a car's speed. He wrote that as a general rule, people should drive with the windows down around the city and turn the air conditioning on when hitting the highway, where a car's aerodynamic(空气动力的) characteristics would be influenced by opened windows.
More seriously minded people, however, said to travel as much as possible with windows up and the A/C off. Eddie Xue gets by with just a wisp of outside air. “Use the fan and open your windows every now and then at lower speeds," he wrote.

Tiger research: Indonesia While sustainable tourism helps protect many of the Indonesia's wildlife, one of its rarest species, the Sumatran tiger, suffers as the island's cities expand into its forest habitat. Fortunately Biosphere Expeditions have created a trip that not only benefits the seriously endangered animal, but helps protect it too. Based in a remote camp in the heart of the rainforest, volunteers will be needed to tour the landscape, documenting tracks, kills and scats(粪便) to aid important research into the lives of these big cats.

Cycling tour: Cambodia With an ancient world of temples and jungles, Cambodia is the kind of country that needs to be explored slowly. PEPY Tours offers 621 miles of green fields, dusty orange tracks and winding rivers on its 15-day cycling expeditions. Money goes directly to local people through homestays and lunches, while tours allow visitors to learn Khmer customs and contribute to ongoing community development projects.

Beach stay: Tanzania A winner in the Best for Beach category at the Responsible Tourism Awards 2014, Chole Mjini Island is a tourists' paradise(天堂) located off the coast of Tanzania. With no roads or electricity, guests to the low-impact destination can enjoy a simple life in hand-built tree houses and spend days either stretched out on deserted beaches or searching for whale sharks.

Teaching: Morocco It's the breathtaking beauty that draws tourists to Morocco's High Atlas Mountains, but while the remoteness of the setting may aid its charm it also causes problems. Few inhabitants of the region's rural villages, especially females, continue their education past primary school. Education For All (EFA) is a Moroccan NGO that builds and runs girls' boarding houses near secondary schools in the High Atlas, making further education theoretically possible. Based in the beautiful town of Asni, the programme is looking for female volunteers with teaching experience.
