Fuel economy and efficiency: How far can you REALLY travel when the fuel light comes on? | Cars | Life & Style
Fuel economy is an incredibly important feature of any car.
With the price of fuel rising, the cost of owning a car increase and car tax and insurance prices saving cash at the pumps is incredibly appealing.
The majority of drivers on the road have, however, pushed it a few times when the fuel indicator light comes on.
It is a tense moment when the light turns on as there is no real way to gauge how much fuel your car has left.
Of course there is a reserve of fuel in the tank and your car won’t just cut out as soon as it hits ‘empty’.
Drivers, however, should not rely on the fact there is a reserve in the tank as it could actually end up costing you in repairs.
When fuel levels get low the car can start picking up debris from the bottom of the fuel tank.
This can damage the fuel filter and pump and also have a negative effect on the catalytic converter.
If your fuel pump runs dry as a result of you running out of fuel, it can land you a bill of up to £200 to repair.
There is no definitive way you can work out exactly how much fuel will be left as it will depend on multiple factors such as the condition of your car, the environment, driving style and speed etc.
In addition to this the size of your car will also affect how far you can go.
For example, hatchbacks and smaller cars achieve around 30 miles while larger SUVs can reach 90-plus after the warning light comes on.
US-based website YourMechanic has however drawn up a list of cars of popular cars and how far they can travel on reserve fuel.
One way you could gauge a rough estimate of how much fuel may be left in your tank when the indicator light comes on is by checking the exact volume of toys fuel tank, which should be displayed in your owners manual and then the next time the needle hits empty fill the car up.
Subtract the number of gallons it took to fill up your fuel tank by the overall volume of your tank and you should have a better indication about how much fuel is left.
These digital readouts and estimation are, however, only a rough guideline and drivers should never really run the risk.
A good rule of thumb is if you see the light come on then fill up as soon as you can.
