Here at MRT we are all about having fun PLUS doing the right thing.
So when you can think of how your actions effect others.

One way is to reduce emissions, use less fuel and save money on buying fuel! 

SAVE $$ on the Purchase of fuel

Only buy or fill up your car in the early morning when the ground temperature is still cold. Remember that all service stations have their storage tanks buried below ground. The colder the ground the more dense the fuel, when it gets warmer petrol expands,so buying in the afternoon or in the evening....your litre is not exactly a litre. In the petroleum business, the specific gravity and the temperature of the petrol, diesel and jet fuel, ethanol and other petroleum products plays an important role. A 1-degree rise in temperature is a big deal for this business. But the service stations do not have temperature compensation at the pumps.

When you're filling up do not squeeze the trigger of the nozzle to a fast mode. If you look you will see that the trigger has three (3) stages: low, middle, and high. In slow mode you should be pumping on low speed, thereby minimizing the vapours that are created while you are pumping. All hoses at the pump have a vapour return. If you are pumping on the fast rate, some of the liquid that goes to your tank becomes vapour. Those vapours are being sucked up and back into the underground storage tank so you're getting less worth for your money.

One of the most important tips is to fill up when your tank is HALF FULL. The reason for this is, the more fuel you have in your tank the less air occupying its empty space. petrol evaporates faster than you can imagine. Petroleum storage tanks have an internal floating roof. This roof serves as zero clearance between the petrol and the atmosphere, so it minimizes the evaporation. Unlike service stations, every truck that is loaded is temperature compensated so that every litre is actually the exact amount.

Another reminder, if there is a fuel truck pumping into the storage tanks when you stop to buy, DO NOT fill up - most likely the petrol/diesel is being stirred up as the fuel is being delivered, and you might pick up some of the dirt that normally settles on the bottom.

Hope this will help you get the most value for your money.


The keys to climate control are in your hands.

You can boost the overall fuel-efficiency of your car as much as 30% by simple vehicle maintenance and attention to your style of driving.

Here are some tips on fuel-efficient driving that will not only reduce greenhouse gas emissions and other pollutants, but could save you hundreds of dollars a year in fuel costs.



Avoid aggressive driving.
Fast starts and hard braking can increase fuel consumption by as much as 40%. Tests show that fast starts and hard braking reduces travel time by only four percent, while toxic emissions were more than five times higher. The proper way is to accelerate slowly and smoothly, then get into high gear as quickly as possible. In city driving, nearly 50% of the energy needed to power your car goes to acceleration.

Drive steadily at posted speed limits.
Increasing your highway cruising speed from 90km/h to 120km/h can raise fuel consumption as much as 20%. You can improve your fuel economy 10 - 15% by driving at 90 km/h rather than 104km/h.
Note how quickly efficiency drops after
90 km/h .  

Avoid idling your vehicle,
in both summer and winter. Idling wastes fuel, gets you nowhere and produces unnecessary greenhouse gases. If you're going to be stopped for more than 30 seconds, except in traffic, turn off the engine. In winter, don't idle a cold engine for more than 30 seconds before driving away. (Older vehicles, however, may need more idling time when first started. In cold, winter conditions all vehicles may need more idling time to warm up and ensure the windshield is fully defogged. Be sure your vehicle is warmed enough to prevent stalling when you pull out.)

Make sure your tyres are properly inflated
to prevent increased rolling resistance.
Under-inflated tyres can cause fuel consumption to increase by as much as 6%.
Check tyre pressure at least once a month, when the tyres are 'cold' (i.e. when the vehicle has not been driven for at least three hours or for more than 2km). Start by checking tyre pressures in your driveway. Note any tyre that is underinflated, and then drive to the nearest location to add air. Check
tyre pressures again, and inflate the low tyre to the same level as the others (these will likely have higher pressure than they did in the driveway, since the tyre have heated up.)
Radial tyre can be under inflated yet still look normal.
Always use your own tyre gauge for consistent results. On average, tyre lose about 1 psi per month and 1 psi for every 10 degree drop in temperature.
To determine the correct
tyre inflation for your car, consult the car's operator manual or ask your tyre dealer. Do not inflate your tyre to the 'maximum allowed' pressure which is marked on the side of your tires.

Select the right gear.
Change up through the gears and into top gear as soon as possible without accelerating harder than necessary. Driving in a gear lower than you need wastes fuel; so does letting the engine labour in top gear on hills and corners. Automatic transmissions will shift up more quickly and smoothly if you ease back slightly on the accelerator once the car gathers momentum.

Use your air conditioner sparingly.

Using a vehicle’s air conditioner on a hot summer day can increase fuel consumption as much as 10% in city driving. If it’s cool enough, use the flow-through ventilation on your car instead of the air conditioner. At low speeds, opening the window will also save reduce fuel consumption by reducing A/C use. At higher speeds however, using the A/C may be more efficient than the wind resistance from open windows and sunroof.

Use the cruise control
On long stretches of highway driving, cruise control can save fuel by helping your car maintain a steady speed.

Choose the octane fuel which best suits your car.
Premium, high-octane fuels aren't necessarily the best choice for your car; higher price doesn't guarantee better performance. Refer to MRT direct for the easy way to work out the best way to choose the fuel thyat suits your car. or Check your owner's manual for a general notice to see what your car requires.

Service your vehicle regularly,
according to the manufacturer's instructions. A poorly tuned engine can use up to 50% more fuel and produces up to 50% more emissions than one that is running properly.

  Air filters: Dirty air filters can also cause your engine to run at less than peak efficiency Regular visual checks of the air filter will tell you if it needs replacing and your owner's manual will also recommend appropriate replacement intervals. Clogged filters can cause up to a 10% increase in fuel consumption.
Using the correct viscosity oil is important because higher viscosity oils have greater resistance to the moving parts of the engine, and therefore use more gas. Clean oil also contributes to better gas mileage. It is usually recommended that engine oil be changed every three to five thousand miles. Synthetic oils add value as they generate less resistance inside the engine allowing more power to be generated.

Monitor power accessories.
Be sure to shut off all power-consuming accessories before turning off the ignition. That way, you decrease engine load the next time you start up. Items that plug into your vehicle's cigarette lighter, such as TV consoles for mini-vans and SUVs, can cause the alternator to work harder to provide electrical current. This adds a load to the engine and added load increases fuel use, decreasing your gas mileage.

Tighten your fuel cap.
If you don't tighten up the fuel filler cap to the second click, fuel can evaporate. According to the US Car Care Council (, loose, missing or damaged gas caps cause 147 million gallons of gas to evaporate every year.

Think "aerodynamic" and "lightweight".
Reduce drag. Out on the open highway, keep windows rolled up to reduce drag. Remove bicycle and ski racks when not in use. Excess weight also uses more fuel. Remove unnecessary items from inside the vehicle, boot or truck bed. An extra 48 kg of weight can increase your fuel bill by 2%.

Park in shady areas when possible.
Besides helping to keep your car cool, which reduces the need for air conditioning, parking in the shade also minimizes the loss of fuel due to evaporation.

Cold weather driving?
Use a block heater
when the winter temperature drops to -20°C or below. A block heater keeps your engine oil and coolant warm, which makes the vehicle easier to start and can reduce winter fuel consumption by as much as 10%. Use a timer to switch on the block heater one or two hours before you plan to drive.

If you're in the market for a new car, why not purchase the most fuel-efficient model that meets your needs? Check its its fuel consumption rating.

Plan your trip,
whether you are going across town or across the country. Try to combine several errands in one outing, and plan your route to avoid heavy traffic areas, road construction, hilly trerrain, etc. With a little organization, you can group your "town tasks" into fewer trips, saving you time and fuel expense.

Make a commitment to drive less,
by walking to some nearby destinations. It's good for your health and the environment. Approximately 50% of car use is for trips within 3 km's of the home. This distance is within the range for easy biking, so it makes sense to try to use your bike for some of these short hops. You'll be saving fuel and reducing pollution, and you can also save on trips to the gym with this added exercise.

Changing the oil in your car?
Disposing of used motor oil by pouring it into storm or sewer drains, dumping it onto the ground, or placing it with household trash may create risks to human health and the environment.
Human health is affected if rainwater carries metal-laden oil into underground streams and contaminates drinking water. It is almost impossible to clean up groundwater once it has been contaminated. Surface runoff from ground disposal and oil poured down drains often lead to water treatment plants, streams or rivers, which can also affect drinking water supplies.

Used oil from a single oil change can ruin a million gallons of fresh water, a year's supply for 50 people.

Pour all collected used oil into a clean, empty, sealable container such as a plastic milk jug. Specialized used oil containers can be purchased at local auto parts stores. Take it to a used oil collection site (UOCS) that accepts and recycles used motor oil. These sites, generally places such as service stations that sell motor oil, can be identified by an amber and black "Recycle Oil" logo.

"Hi, Your site says "You can boost the overall fuel-efficiency of your car as much as 30% by ..."

Make that closer to 40%. I get 72 MPG regularly, but my 2003 VW Jetta TDi's official EPA combined estimate is only 45. No custom tech, just efficient driving. And that's not pure highway driving either. My last tank was 69.9 MPG with 40% city driving. The car's efficient diesel engine helps too. Also, the Wall Street Journal mentioned a Honda Insight owner who gets 100 MPG on occasion -- that's fully 58% better than the official combined of 63 MPG".    Alexander Passmoore

"Not all cars get the best economy at 55MPH, it depends on gear ratio, I have had cars that deliver better fuel economy at 70 MPH, Like a 1970 Plymouth Duster I had years ago, it got over 21MPG at 70 MPH pulling a double snow mobile trailer with two machines on it and it was over 340 Horse Power. And my 1986 Corvette will get 32 MPH at a steady 70MPH, and only about 28MPH at 55 MPH. Thank You"   Richard Heater
