10 Top Tips for Fuel Efficient Driving

1. Minimise your vehicle use
Vehicles are least fuel efficient and most polluting at the start of trips and on short trips. One reason for this is that catalytic converters (which reduce air pollution emissions) do not operate properly until they have warmed up. Trips of less than five kilometres generally do not allow the engine to reach its peak operating temperature.

Plan to do a number of errands in one trip rather than several trips and save both time and fuel. Try to avoid short vehicle trips by walking or cycling. This will save over a quarter of a kilogram of greenhouse gas emissions per kilometre of vehicle driving it replaces, as well as give you healthy exercise.

2. Drive in the right gear
Driving in a gear lower than you need wastes fuel, and letting the engine labour in top gear on hills and corners is also wasteful. In a manual vehicle, change up gears as soon as the car is comfortable with the higher gear but without accelerating harder than necessary.

Automatic transmissions will shift up more quickly and smoothly if you ease back slightly on the accelerator once the car gathers momentum. Avoid the use of power options which drop the car into a lower gear and therefore use more fuel.

3. Drive smoothly
Stop/start driving is much less efficient and more polluting than driving at a constant speed. Avoid travelling during peak-hours and on congested roads whenever possible.

Take it easy on the accelerator - more revs equals more petrol use. Drive at a good distance from the car in front so you can anticipate and travel with the flow of traffic. This avoids unnecessary acceleration and frequent repetitive braking that ends up wasting fuel. It's also far safer. If you see traffic stoppages ahead, first take your foot off the accelerator and let the engine's drop in power slow the vehicle, particularly by also changing to a lower gear. Don't continue to drive at the same speed and applying the brakes at the last minute. Getting back to cruising speed while the car is still moving uses far less petrol than stopping and then starting again.

4. Minimise fuel wasted in idling
Most cars don't need to be "warmed up" by idling before setting off. This simply wastes fuel. Start your car when you are ready to go. Once on the road, minimise fuel wasted in idling by stopping the engine whenever your car is stopped or held up for an extended period of time. By having the engine switched off, even for a short period, you will save more fuel than is lost from the burst of fuel involved in restarting the engine. The net increased wear and tear from this practice is negligible.

5. Don't Speed
Fuel consumption increases significantly over about 90 km/h. At 110 km/h your car uses up to 25 per cent more fuel than it would cruising at 90 km/h. If your car is fitted with cruise control, using it during highway driving will help to maintain a steadier speed, which will save fuel.

6. Minimise aerodynamic drag
Additional parts on the exterior of a vehicle such as roof racks and spoilers, or having the window open, increases air resistance and fuel consumption, in some cases by over 20 per cent at higher speeds. Take off roof and bike racks when not in use. If you have to use roof racks, load them carefully to help minimise wind resistance or use a streamlined roof box.

7. Look after your vehicle's tyres
Inflate your vehicle's tyres to the highest pressure recommended by the manufacture and make sure your wheels are properly aligned. Looking after your tyres will not only reduce your fuel consumption it will also extend tyre life and improve handling.

8. Use airconditioning sparingly
Airconditioners can use about 10 per cent extra fuel when operating. However, at speeds of over 80 km/h, use of airconditioning is better for fuel consumption than an open window as this creates aerodynamic drag. If it is hotter inside your car than outside when you start a trip, drive with the windows down for a few minutes to help cool the car before starting the airconditioning.

9. Travel light
The more weight a vehicle carries, the more fuel it uses..Don't use your car as a mobile store room. Leave heavy items like tools and sports equipment at home when you don't need them on a trip.

10. Keep your vehicle in good condition
Keep your vehicle well tuned and regularly maintained. Get your car serviced at the intervals specified in the manufacturer's handbook.

Use the petrol that is recommended for your vehicle by the manufacturer. If you use regular unleaded in a car designed to run on premium unleaded you can expect slightly less performance and fractionally higher consumption. Using premium unleaded petrol in a car designed for regular unleaded may give better fuel consumption in some newer vehicles but it is unlikely to offset the extra cost of the fuel.

Car Ads: Reading Between the Lines

Many new car dealers advertise unusually low interest rates and other special promotions. Ads promising high trade-in allowances and free or low-cost options may help you shop, but finding the best deal requires careful comparisons.

Many factors determine whether a special offer provides genuine savings. The interest rate, for example, is only part of the car dealer’s financing package. Terms like the size of the downpayment also affect the total financing cost.

Questions About Low Interest Loans
A call or visit to a dealer should help clarify details about low interest loans. Consider asking these questions:
  • Will you be charged a higher price for the car to qualify for the low-rate financing? Would the price be lower if you paid cash, or supplied your own financing from your bank or credit union?
  • Does the financing require a larger-than-usual downpayment? Perhaps 25 or 30 percent?
  • Are there limits on the length of the loan? Are you required to repay the loan in a condensed period of time, say 24 or 36 months?
  • Is there a significant balloon payment —possibly several thousand dollars — due at the end of the loan?
  • Do you have to buy special or extra merchandise or services such as rustproofing, an extended warranty, or a service contract to qualify for a low-interest loan?
  • Is the financing available for a limited time only? Some merchants limit special deals to a few days or require that you take delivery by a certain date.
  • Does the low rate apply to all cars in stock or only to certain models?
  • Are you required to give the dealer the manufacturer’s rebate to qualify for financing?

Questions About Other Promotions
Other special promotions include high trade-in allowances and free or low-cost options. Some dealers promise to sell the car for a stated amount over the dealer’s invoice. Asking questions like these can help you determine whether special promotions offer genuine value.
  • Does the advertised trade-in allowance apply to all cars, regardless of their condition? Are there any deductions for high mileage, dents, or rust?
  • Does the larger trade-in allowance make the cost of the new car higher than it would be without the trade-in? You might be giving back the big trade-in allowance by paying more for the new car.
  • Is the dealer who offers a high trade-in allowance and free or low-cost options giving you a better price on the car than another dealer who doesn’t offer promotions?
  • Does the "dealer’s invoice" reflect the actual amount that the dealer pays the manufacturer? You can consult consumer or automotive publications for information about what the dealer pays.
  • Does the "dealer’s invoice" include the cost of options, such as rustproofing or waterproofing, that already have been added to the car? Is one dealer charging more for these options than others?
  • Does the dealer have cars in stock that have no expensive options? If not, will the dealer order one for you?
  • Are the special offers available if you order a car instead of buying one off the lot?
  • Can you take advantage of all special offers simultaneously?
You’re not limited to the financing options offered by a particular dealer. Before you commit to a deal, check to see what type of loan you can arrange with your bank or credit union.

Once you decide which dealer offers the car and financing you want, read the invoice and the installment contract carefully. Check to see that all the terms of the contract reflect the agreement you made with the dealer. If they don’t, get a written explanation before you sign. Careful shopping will help you decide what car, options, and financing are best for you.

The Low-Down on High Octane Gasoline

Are you tempted to buy a high octane gasoline for your car because you want to improve its performance? If so, take note: the recommended gasoline for most cars is regular octane. In fact, in most cases, using a higher octane gasoline than your owner's manual recommends offers absolutely no benefit. It won't make your car perform better, go faster, get better mileage or run cleaner. Your best bet: listen to your owner's manual.


The only time you might need to switch to a higher octane level is if your car engine knocks when you use the recommended fuel. This happens to a small percentage of cars.

Unless your engine is knocking, buying higher octane gasoline is a waste of money, too. Premium gas costs 15 to 20 cents per gallon more than regular. That can add up to $100 or more a year in extra costs. Studies indicate that altogether, drivers may be spending hundreds of millions of dollars each year for higher octane gas than they need.

What are octane ratings?
Octane ratings measure a gasoline's ability to resist engine knock, a rattling or pinging sound that results from premature ignition of the compressed fuel-air mixture in one or more cylinders. Most gas stations offer three octane grades: regular (usually 87 octane), mid-grade (usually 89 octane) and premium (usually 92 or 93). The ratings must be posted on bright yellow stickers on each gasoline pump.

What's the right octane level for your car?
Check your owner's manual to determine the right octane level for your car. Regular octane is recommended for most cars. However, some cars with high compression engines, like sports cars and certain luxury cars, need mid-grade or premium gasoline to prevent knock.

How can you tell if you're using the right octane level?
Listen to your car's engine. If it doesn't knock when you use the recommended octane, you're using the right grade of gasoline.

Will higher octane gasoline clean your engine better?
As a rule, high octane gasoline does not outperform regular octane in preventing engine deposits from forming, in removing them, or in cleaning your car's engine. In fact, the U.S. Environmental Protection Agency requires that all octane grades of all brands of gasoline contain engine cleaning detergent additives to protect against the build-up of harmful levels of engine deposits during the expected life of your car.

Should you ever switch to a higher octane gasoline?
A few car engines may knock or ping - even if you use the recommended octane. If this happens, try switching to the next highest octane grade. In many cases, switching to the mid-grade or premium-grade gasoline will eliminate the knock. If the knocking or pinging continues after one or two fill-ups, you may need a tune-up or some other repair. After that work is done, go back to the lowest octane grade at which your engine runs without knocking.

Is knocking harmful?
Occasional light knocking or pinging won't harm your engine, and doesn't indicate a need for higher octane. But don't ignore severe knocking. A heavy or persistent knock can lead to engine damage.

Is all "premium" or "regular" gasoline the same?
The octane rating of gasoline marked "premium" or "regular" is not consistent across the country. One state may require a minimum octane rating of 92 for all premium gasoline, while another may allow 90 octane to be called premium. To make sure you know what you're buying, check the octane rating on the yellow sticker on the gas pump instead of relying on the name "premium" or "regular."

HYPERTHERMIA (Heatstroke)

Problem : Children die each year from heatstroke, after being left alone in a vehicle.

You live by your daily routine and it helps you get things done. Be extra careful, though, if you have to change any part of that routine. This is more likely to happen when you, or caregiver who helps with your children, forgets that a child is in the back seat. This can and does happen when you break a well-established routine.

Disasters happen quickly
At other times, you are on your way home and realize you need to stop in at the store and pick up one or two things for dinner. So, you leave your child unattended, thinking, "I'll just run into the store for a minute." Even cool temperatures in the 60s can cause the temperature to rise well above 110° Fahrenheit inside your car. The inside temperature can rise almost 20 degrees within the first 10 minutes.

Some children die in hot cars after climbing into an unlocked vehicle without an adults' knowledge. Once in the vehicle, they may become confused by the door opening mechanism or trapped in the trunk, and unable to get out before heatstroke occurs.

Prevention Tips :
  • Never leave a child unattended in a vehicle.
  • Do not let your children play in an unattended vehicle. Teach them that a vehicle is not a play area.
  • Never leave infants or children in a parked vehicle, even if the windows are partially open.
  • Make a habit of looking in the vehicle - front and back - before locking the door and walking away.
  • If you are dropping your child off at childcare, and normally it's your spouse or partner who drops them off, have your spouse or partner call you to make sure the drop went according to plan.
  • Ask your childcare provider to call you if your child does not show up for childcare.
  • Do things to remind yourself that a child is in the vehicle, such as

  • Writing yourself a note and putting the note where you will see it when you leave the vehicle;
  • Placing your purse, briefcase or something else you need in the back seat so that you will have to check the back seat when you leave the vehicle; or
  • Keeping an object in the car seat, such as a stuffed toy. When the child is buckled in, place the object where the driver will notice it when he or she is leaving the vehicle.
  • Always lock vehicle doors and trunks and keep keys out of children's reach. If a child is missing, check the vehicle first, including the trunk.
  • If you see a child alone in a hot vehicle, call the police. If they are in distress due to heat, get them out as quickly as possible. Cool the child rapidly. Call 911 or your local emergency number immediately.
What you need to know, now:
  • Vehicles heat up quickly - even with a window rolled down two inches, if the outside temperature is in the low 80s° Fahrenheit, the temperature inside a vehicle can reach deadly levels in only 10 minutes.
  • Children's bodies overheat easily, and infants and children under four years of age are among those at greatest risk for heat-related illness.
  • Children's bodies absorb more heat on a hot day than an adult. Also, children are less able to lower their body heat by sweating. When a body cannot sweat enough, the body temperature rises rapidly.
  • In fact, when left in a hot vehicle, a young child's body temperature may increase three to five times as fast an adult. High body temperatures can cause permanent injury or even death.
Dangers of extreme heat :
  • Symptoms of heatstroke : Warning signs vary but may include: red, hot, and moist or dry skin, no sweating, a strong rapid pulse or a slow weak pulse, a throbbing headache, dizziness, nausea, confusion, being grouchy, or acting strangely.
  • If you see a child alone in a hot vehicle, call the police. If they are in distress due to heat, get them out as quickly as possible. Cool the child rapidly.

Frequently asked Question about Smog Check Program

Q What are the environmental benefits of the Smog Check Program?
A The Smog Check Program has greatly reduced air pollution created by millions of cars in California. According to the California Air Resources Board, the program removes about 400 tons of smog-forming pollutants from California’s air every day.

Q Is my vehicle required to get a Smog Check?
A Your vehicle needs a Smog Check if it is more than six model years old and the model year is 1976 or newer. (This does not include diesel vehicles, motorcycles, electric and hybrid vehicles, and two-cylinder engine vehicles.)

Q How can I help my vehicle pass a Smog Check?
A Performing proper and regular vehicle maintenance according to your owner’s manual, and not tampering with the emissions control equipment are keys to passing Smog Check.

Q How often does my vehicle have to be tested?
A Your vehicle must be tested every other year. A Smog Check is also required if you sell your vehicle and it is more than four model years old. Some vehicles may require a Smog Check at a Test-Only or Gold Shield station.

Q What happens if my vehicle fails a Smog Check?
A In order to complete your registration, you will need to obtain the repairs necessary for it to pass its Smog Check retest. Before beginning repairs, find out if you are eligible for our Consumer Assistance Program (CAP).

Q What is a Test-Only station?
A Test-Only stations are licensed Smog Check stations that are only allowed to test cars. State law prohibits them from making repairs.

Q What is CAP and how do I qualify?
A The Consumer Assistance Program (CAP) provides financial assistance to repair or retire a vehicle that fails a Smog Check.

Repair Assistance — If your DMV renewal notice requires a Smog Check at a Test-Only or Gold Shield station, you may qualify for up to $500 in repair assistance once you pay the first $100 in repair costs. You may also qualify if your income is within certain levels, regardless of where you got your Smog Check. If you qualify based on income, a $20 co-pay is all that you need.

Vehicle retirement — If you feel your car is not worth repairing, the State may buy the car from you for $1,000 and have it scrapped at a local dismantler.

Q What is a Gold Shield station?
A Gold Shield stations are licensed Smog Check stations that meet certain performance criteria in order to test and repair all cars. They also provide repairs on vehicles that qualify for financial assistance under the Consumer Assistance Program (CAP).

Q How will I know if I need to take my car to a Test-Only or Gold Shield station?
A You will be notified on the registration renewal notice sent by the California Department of Motor Vehicles (DMV) if your vehicle must be inspected at a Test-Only or Gold Shield station.

Reducing greenhouse gas emissions

For every litre of petrol used in a motor vehicle, 2.3 kilograms of carbon dioxide (CO2 ), a major greenhouse gas, is released from the exhaust. The Australian transport sector accounts for around 76 million tonnes of Australia's total net greenhouse gas emissions, representing 13.5 per cent of Australia's total emissions.

Emissions from different fuels

Fuels differ in the amount of carbon and energy they contain as well as other characteristics, with implications for fuel economy and greenhouse emissions. The table below lists the amount of CO2 emitted from the exhaust for each litre of a particular fuel covered by the calculator.

CO2 Tailpipe Emissions/Litre of Fuel Consumed

Fuel Type CO2 Emissions

Petrol 2.3 kg
LPG 1.6 kg
Diesel 2.7 kg

It might seem odd that a greater weight of emissions is produced than the weight of a litre of fuel, but this is because of the addition of oxygen from the atmosphere to the fuel during combustion to form CO2.

This is not the end of the story because it also matters how much fuel is consumed to travel a given distance. LPG has lower greenhouse emissions per litre of fuel consumed than petrol, but also has a lower energy content. Therefore equivalent vehicles tend to consume more of LPG than petrol to travel a given distance. In the case of diesel, its greenhouse emissions per litre are higher than petrol, but engines designed to operate on diesel tend to be far more fuel-efficient than petrol engines. To be sure that one vehicle has lower greenhouse emissions than another use the calculator provided.
You can make a difference

Purchasing a vehicle with low fuel consumption and driving it efficiently can make a real difference to the amount of greenhouse gas emissions it produces. The following table gives an indicative guide to annual CO2 tailpipe emissions from petrol vehicles travelling 15,000 kilometres annually.

CO2 Tailpipe Emissions from Petrol Vehicles

Fuel Consumption Annual CO2 Emissions

6 L/100km 2160 kg
8 L/100km 2880 kg
10 L/100km 3600 kg
12 L/100km 4320 kg
