What causes high fuel consumption in petrol engines?
He adds; “When it comes to petrol engines, failure to replace worn out spark plugs, air cleaner elements or fuel filters as well as maintenance of the throttle valve and oxygen sensors will lead to an increase in fuel consumption.”
What causes excessive petrol consumption?
If your fuel injectors are faulty and insufficient fuel is being injected into the engine, your car won’t run efficiently. A less efficient engine means increased fuel consumption. Air filters and oxygen sensors ensure that the ratio of air and fuel going into the engine is correct for optimum performance.

Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km.
What will reduce fuel consumption?
Explanation: Harsh braking, frequent gear changes and harsh acceleration increase fuel consumption. An engine uses less fuel when travelling at a constant low speed. Easing off the accelerator and timing your approach at junctions, for example, can reduce the fuel consumption of your vehicle.
Which driving technique saves fuel?
Explanation: Missing out intermediate gears, when appropriate, helps to reduce the amount of time spent accelerating and decelerating – the times when your vehicle uses the most fuel.
Will an oil change make my car run better?
Changing your oil offers a lot of noticeable benefits, as well. Regular oil changes improve your car’s gas mileage. As the fresh oil moves through the engine, the lubrication of the metal parts increases your engine’s performance and helps it run more efficiently with less work so it doesn’t eat up as much gas.
What’s the difference between Nissan impendulo and Toyota quantum?
