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.

    Six years ago at the age of 35,I suddenly decided I wanted to learn the cello（大提琴）.Straight away I rented an instrument and appeared before Wendell Margrave,professor of musical instruction.

    "You can be as good as you want to be,"Margrave said rather mysteriously.On a piece of paper he drew the notes E and F.He showed me where to put my fingers on the neck of the cello and how to draw the bow.Then he entered my name in his book: 10 am,Tuesday.Tuesday followed Tuesday,and soon it was spring.

     Thus began my voyage out of ignorance and into the dream.E-F,E-F,we played together—and moved on to G.It was a happy time.I was again becoming something new,and no longer trapped as the same person.Surely the most terrible recognition of middle life is that we are past changing.We do what we can already do.The cello was something I couldn't do.Yet each Tuesday this became less and less true.Riding home on the bus one snowy night and learning the score of Mozart's C-Major Quintet(莫扎特的C大调五重奏),I felt the page burst into music in my hands.I could by then more or less read a score,and was humming（哼唱）the cello line,when suddenly all five parts came together harmonically（和谐地） in my head.The fellow sitting opposite stared.I met his glance with tears,actually hearing the music in my head for the first time.Could he hear it too, perhaps?No,he got off at the next stop.

    As the years slipped by,my daughter grew up,playing the piano well.My goal was that she and I would one day perform together.I also wanted to perform in public with and for my peers,and to be secretly envied.I continued to play,to perform,but it is not the same. Before, when I heard a cello,it was all beauty and light.Now,as the TV camera gets close to Rostropovich's face,I recognize that his smile shows his incredible determination.Even for him,the cello is a difficult instrument that doesn't respect your ambitions.I picked up my cello and practiced.As good as I wanted to be,I am as good as I'm going to get.It is good enough.

    Thirteen hours later we just arrived in Paris after many dramas (戏剧性事件).

    I rented a car, filled it up and moved ahead to Bristol airport that morning. We set off at 8:00 a.m. and all was going well until we got to the turn for Bristol airport. The airport sign (指示牌) suggested we went out from the M5, but Suri asked me to continue going straight ahead, so against my better judgment, I let the airport turn pass us by.

    Next we left for South Wales, the car was back and we had a plane to Paris to catch in a couple of hours. It was about then that I realized we were heading for Wales on a six­road highway. I felt very bad. We turned off the highway and turned into a country road, as directed by Suri and there was a sign saying that the road to the airport was closed. I saw a lady watering her garden and asked her about the best way to the airport. She said we were at least 30 minutes from the airport, but she couldn't help us with the right directions (方向).

    I was so worried as we really were out in the country without any guidance. All I could think of was to turn Suri off and follow the signs myself.

    Then finally after many butterflies in the stomach and feeling like my heart was going to burst (爆裂) out of my chest, there was a proper green sign to the airport and we followed it with so much joy.

    Driving from the airport into Paris was a shock, Lots of homeless people were sleeping under the highways with rubbish everywhere.

Anyway we're now in Paris. The experience of getting lost is now almost laughable. In another 24 hours will be my 50th birthday. I have a big party planned for myself in Paris.
