how we can improve the quality of petrol ?
Answers
1. Check your tire pressure at least once a month. Under-inflated tires burn more fuel. If tires are 8 pounds under inflated, (not an uncommon condition), rolling resistance of the tires increases by 5 per cent.
2. At the pump, keep the hose in the tank until after the pump shuts off and make sure you allow all the fuel to pour out of the nozzle. As much as a quarter of a cup can pour from the hose. It's yours, you paid for it.
3. When appropriate, use your cruise control. This can save you up to 6 per cent in fuel consumption on the highway.
4. Corroded battery cables cause the alternator to work harder, using more gas. Have them cleaned as a matter of course with each engine check-up.
5. Don't let the vehicle idle for more than a minute. Idling consumes half-a-gallon to one gallon of gas per hour and pumps needless CO2 into the atmosphere. The modern engine will consume less fuel turning off and re-starting than idling for extended periods. We are already being faced with no-idle zones. Also, to effectively warm an engine, drive it, don't rev it. Engines only work hard under load and will warm up much quicker if you simply start the engine, wait for 20 seconds, (this builds the oil pressure,) and drive away.
6. Change the air filter at least the set number of times outlined in the owners manual, more if you drive in dusty conditions.
7. Have a regular engine check-up. Since the advent of computer controlled fuel injection, there is no such thing as an old fashioned "tune-up" any more. At worst, you may be expected to replace spark plugs, oxygen sensor, the air and fuel filters.
8. If your car was built since the mid-1980s, chances are it has an oxygen sensor in its exhaust system. It should be replaced just as you would spark plugs, following the manufacturer's recommendations. This little device trims the fuel delivery and has a profound effect on fuel economy in the process.
9. Driving in the highest gear possible without labouring the engine is a fuel-efficient way of driving. Driving at 60 km/h, a vehicle will use 25 per cent more fuel in third gear than it would in fifth. Travelling at fast rates in low gears can consume up to 45 per cent more fuel than is needed. If you have an onboard trip computer, you probably have an "Instant fuel economy" setting. Watch this gauge and keep the litres per 100 kilometres as low as you can. The manufacturers have turned this into a bit of a game. The new Ford Fusion Hybrid has a leafy graphic display that sprouts leafs each time you reach a fuel economy milestone. I had the opportunity to drive one and each time we pulled into the driveway, my son would ask "How many leaves on the tree, Dad"?
10. Think ahead! Drive smoothly. By applying light throttle and avoiding heavy braking, you can reduce both fuel consumption and wear and tear. Research suggests driving techniques can influence fuel efficiency by as much as 30 per cent.
hope it helps ☺
