    Coasting when not in gear uses more fuel than staying in gear.

    If you feel the car juddering it cannot be good imo. It must strain something as its struggling to keep going. Change down accordingly and use engine braking to slow you - this will help to save wear on the brakes too.
    Now I need a turbo to keep up!

    coasting isnt the best of moves it does affect the braking and in the event of emergency braking it will just lock up the wheels and you stand more chance of skidding, where as if you was in a gear, they help to slow the car down aswell the brakes.

    in regards to going to the 5th 6th gear quickly doesnt save fuel. if your in the wrong gear your put strain on the engine..... even if your look at the manufacture hand book you will find a eco drive guide.... you should find something like doing 40 or 50mph you should be in 4th or 5th gear, because of how the gear ratios are set at thoses revs the ecu will be programed to supply less fuel to the engine but still have enough power to make you move when you push the pedal.

    Letting the engine "labour" does more damage than over reving it.

    Replacing an engine &/or gearbox will cost more than a bit of fuel, even if you do manage to save some.

    Don't labour your engine, I posted some time ago about a friends mom who blew up her new Focus by driving round a bent in 5th gear labouring the engine.

    You REALLY don't want to do this.

    Also driving anywhere outside the torque band is highly inefficient, peak torque is where the engine is making the most efficient use of fuel.

    If your really so intent on saving fuel, turn off the AC, use the cruise control when possible, don't open the windows (wrecks aerodynamics), keep your tyres at the correct pressure, service the car regularly, keep the air filter clean, don't carry passengers, don't carry anything you don't need, don't eat so many pies.
    and avoid short journey's at all costs.

    If however any of us see you driving at night with no lights or just parking lights (which doesn't affect fuel consumption)... We will kill you!

    i just thought i would save the engine and fuel as i thought when you coast your in effect not not engaging the engine there for no strain
