Putting petrol in a diesel car strips away vital lubrication, destroying the fuel pump and injectors. If misfuelled, do not start the engine and call for a professional fuel drain service immediately to avoid a total engine failure.


What could happen if you put petrol in a diesel car?

Kerosene-based jet fuel is preferred over petrol due to its higher flash point of 38 degrees Celsius and a lower freezing point reaching -47 degrees Celsius.


Why petrol is not used as fuel in commercial aircraft

Wider tyres increase rolling resistance and aerodynamic drag, leading to a 1 to 3 per cent drop in fuel economy. For EVs, the range can decrease by 10 per cent. 

Do wider tires decrease fuel mileage?

Roof racks increase aerodynamic drag, cutting mileage by up to 25 per cent at high speeds. Extra weight also forces engines to work harder. Removing unused racks and clearing your boot can significantly reduce daily fuel costs.


Does extra weight and roof racks reduce a car’s mileage?

By adopting smooth driving techniques and maintaining correct tyre pressure, motorists can cut fuel consumption by up to 25 per cent, saving thousands annually.

‘Save fuel and money’: 7 driving habits you should follow

Running your car's air conditioning consumes between 0.2 and 0.8 litres of fuel per hour, increasing your overall petrol or diesel consumption by up to 10 per cent.


How much fuel does a car AC use in 1 hour?

A well-maintained engine can improve your car's fuel efficiency by up to 20 per cent, proving that routine servicing is a direct investment in lower daily running costs.

Does regular servicing actually improve your car’s fuel economy?

Modern cars use EVAP systems to trap fuel vapours, meaning parking in the sun does not cause petrol evaporation. However, shaded parking keeps the cabin cool, reducing the need for heavy air conditioning and ultimately saving fuel.

Does parking in the shade prevent fuel evaporation in the summer?

Using car air conditioning reduces fuel economy by up to 10 per cent. At highway speeds, the AC is more efficient than the aerodynamic drag caused by open windows. City driving favours open windows.

Does driving with the AC on actually ruin your mileage?

With fuel prices constantly fluctuating, finding a car that delivers excellent mileage is critical. Automakers now offer advanced pure petrol and strong hybrid models that achieve between 25.19 km/l and 27.97 km/l, allowing drivers to drastically cut their daily running costs.

‘No need to worry about fuel price hikes’: 5 fuel-efficient cars that can save you money

Cars should be serviced every 12 months or 12,000 miles. High-mileage drivers need an interim check every six months. Regular servicing provides fresh oil and clean filters, which can improve your vehicle's fuel efficiency by up to 20 per cent.


How often should you service your car for better mileage?

Driving between 50 and 60 mph is the ideal speed for fuel savings in most cars. Exceeding 70 mph increases air resistance and burns up to 9 per cent more fuel, while maintaining a steady pace in a high gear maximises efficiency.


What is the ideal car speed for maximum fuel savings?

Driving above 60 mph drastically reduces efficiency, with speeds of 80 mph consuming up to 25 per cent more fuel than cruising at the 70 mph limit.


At what speed does your car consume more fuel?

Petrol cars are universally easier to resell due to wider market demand and lower maintenance. However, factory-fitted CNG vehicles hold strong resale value in metro cities where second-hand buyers want relief from expensive daily fuel costs.


‘Petrol vs CNG’: Which cars are easier to resell?

Idling a car wastes up to two litres of fuel an hour and damages engine parts. Turning the engine off if waiting for over ten seconds saves significantly more petrol than leaving it running, while preventing toxic exhaust emissions.

How much fuel does idling your car really waste?

Modern automatic cars with advanced CVT systems and up to 10 gears now frequently offer better fuel efficiency than manual cars. Computers shift gears more precisely than human drivers, eliminating wasted fuel, especially in heavy urban traffic.

‘Automatic cars vs manuals’: Which uses more fuel?

Driving in a lower gear than necessary can increase fuel consumption by up to 20 per cent. Frequent gear changes and high engine revs waste petrol, while shifting up early and skipping gears helps maintain momentum and maximise fuel efficiency.  


How much fuel do frequent gear changes really waste?

City traffic increases fuel consumption because idling and constant stop-and-start acceleration force engines to work harder in low gears. Conversely, highway driving maintains steady momentum in high gears, maximising your car's fuel efficiency.


Why cars use more fuel in city traffic than on highways

Diesel cars offer 20 to 30 per cent better mileage for long motorway trips. However, for drivers covering shorter city distances, petrol cars save more money due to lower upfront prices and cheaper maintenance costs.


Petrol vs diesel: Which car engine really saves more money in daily driving?

Using your car's AC increases fuel consumption by up to 10 per cent at low speeds. However, at speeds over 50 mph, closing the windows and using the AC is more efficient to avoid massive aerodynamic drag.

How much extra fuel does your car AC really use?

Driving at 120 km/h consumes up to 20 per cent more fuel than cruising at 100 km/h, primarily due to a massive increase in aerodynamic drag.


‘100+ km/h penalty’: How much extra fuel do cars use at high speeds?

Driving between 50 and 60 mph is widely considered the optimum speed for fuel efficiency, while exceeding 70 mph can increase your vehicle's fuel consumption by up to 15 per cent.


What is the best driving speed to save fuel?

To combat climate change and reduce fuel consumption, the Biden administration presented a bold proposal to elevate fuel economy standards by 2032, Reuters reported.

The road to sustainability: Auto industry braces for NHTSA's green revolution

Pakistan is devising ways to tackle the energy crisis in the country in a bid to reduce the energy and fuel consumption. The economically beleaguered country has reduced its official work week to five days from six and now a proposal to shut down markets early is also under consideration.
