    1. a 1.2 is not the smallest engine you can get.

    2. It depends on the car, weight of contents of the car, tyre pressure, road surface etc etc etc

    i dont really see why you'd need to look at it as cost per mile.
    work out how much it costs to fill up your tank, and then how many miles this gives you and that way you can work out the cost per mile.
    and anyway i think its more 15-20p

    it depends on so many things. Your driving style is another factor.

    But, you're much less likely to become an organ donor in a car.

    is it true that going in a higher gear uses less petrol?

    10p per mile is probably only about petrol cost. It's what GM pay in expenses for petrol anyway (having said that VW pay 40p :O ) once you take tax, consumables, car, servicing, insurance etc, it's more like double that, decreasing if you do lots of miles.

    If i push it I can get 50 to the gallon, petrol is 82p a litre at the moment, so that comes to 13.2p a mile in petrol.

    Though the total cost of running a car is much more.

    I think to cover everything you probably want to look at about 30p a mile.

    Higher gear = less revs = less fuel injected into engine so yeah

    If you want to be fuel efficient you should be in 5th for any sustained travel at 30mph+

    Check your maths, 36mpg costs me 10.5ppm.

    But total running costs are 60ppm, if you include depreciation, fuel, tyres, insurance, etc etc.

    If your charging your dad, charge him 20ppm each way, so 10 miles away would be £4 a day. £20 a week sounds about right, but at what your getting from him at the minuet you'll maybe just cover petrol. Depends how much profit you want to make.

    5th at 30 would be less efficient than 4th a 30. Your engine in 5th will be just over tickover and if you need more power, going up a hill, accelerating, etc, it will have to inject loads of fuel to try and make up for having such low torque.

    If you are doing a short trip to college you will get less miles for your pennies. This is because the car has to warm up, heat the engine block and oil and by that time your at college and it cools down again.

    Mine's smaller than yours! I've got 0.6!

    First and last time I get to boast on being smaller in a department methinks on a motoring forum!

    Assuming the principals hold true for a modern car in terms of fuel use, I know that to do 30 in 4th (4 speed gear box), I'm on both chokes, whereas for 30 in third only the small one opens up. Straight line and speed etc.

    Could you wire up a vacuum gauge to incestigate this?



    [that typo ticked me so much on proof reading I'm going to leave it in, maybe even make it habit]
