Please bookmark our real world MPG Calculator and try again after using our fuel saving tips (we bet you get another 50 miles out of a tank)!
Enter Mileage and Fuel used since last fill-up:
Use your trip counter and reset when you fill up ensuring that the tank is full then when empty fill up to full again noting the mileage covered.
TorqueCars Fuel Saving tips:
Allow the car to coast in gear the last 700 yards up to a junction rather than accelerate all the way. Look out for junctions and ease off the throttle as soon as you can.
Drive with a maximum 1/3 to 1/2 throttle - if you get the revs right you will not notice much of a loss of power.
Avoid braking and stopping (2 of the biggest fuel wasters) - anticipate the road ahead and roll up to roundabouts. (If you're good you can avoid using your brakes on a typical journey!!!)
If its hot open the window rather than turn on the air conditioning, if it's really hot open another window and turn the blowers on, if your steering wheel starts melting then turn on the air conditioning. (At speeds over 30mph there is an argument for using the air conditioning to counter the drag from an open window!)
Avoid using things that drain the battery - because extra pull occurs on the alternator requiring more fuel (aircon is very noticeable). The big drains are rear window heater, blowers & heaters, headlights.
Inflate your tires to the correct pressure. (Fully laden pressures or just under seems to give the best MPG but more pressure can increase the mid tyre wear if it's too extreme so don't over do it.) Check your pressures monthly or more frequently - if you calculate your MPG and it is lower then your tyre pressures are usually to blame.
Try to maintain a constant speed - 75 mph uses far more fuel that 65 mph. A distance of 50 miles at 75 mph takes 39.6mins but at 65 it takes 46.2 mins So is 6.6 minutes of your time, the increased risk of being killed, the extra damage to the environment and the extra wear on the engine really worth the extra 25% fuel cost!
Hotter engines are more economical than colder ones - changing the thermostatic control or partially blocking the radiator MAY help on SOME cars. (Run the engine too hot and you will break it - you have been warned.) Use TorqueCars MPG tuning articles for some practical tuning tips to improve your cars MPG.
Empty the boot of tools you've use and haven't got round to taking out, the camping equipment from last year, and the box of junk you have kicking around - less weight = more fuel economy so if you went on a diet that would help as well.
Keep the car well serviced - change the plugs, oil, filters and check the bearings and ensure that the brakes are not dragging. Fully disengage the hand brake as well when you drive off!
Avoid idling the engine for long periods of time - turn it off at railway crossings etc...
Take off the roof rack as the drag this creates really does increase your fuel consumption.
Put some injector cleaning like BG44K Petrol engines or BG244 for diesels in - it really does help keep things at peak efficiency and in my car added 2 mpg!
Fuel magnets did not work for me I wouldn't bother with them!!!
Don't be lazy. Walk to the corner shop - it's only 3 minutes away.
