Heavy on the juice? Solution could be under the bonnet

THE economic downturn has made customers much more conscious of fuel economy. They often come in asking how they can get more MPG from their existing car.

Driving style is clearly important, as is ensuring your tyres are inflated correctly, but the reasons for excessive fuel consumption often lie under the bonnet itself.

If air or fuel filters become blocked or dirty, you will have higher fuel use. Dirty fuel injectors, or a sticking EGR valve, which causes rough idling will have the same result.

A missing or defective thermostat, which causes low operating temperature, can be another factor, as can exhaust backpressure, which stems from a clogged catalytic converter.

All these factors have one thing in common - they are usually the result of not having your car regularly serviced. So skipping that service can be a false economy.
