Fuelling ideas for filling the tank

Fuel, food, interest rates; you name it and its price is going up.

But before you press the panic button, there are many simple ways to save cash. Take your car. You may not have to rush out and buy the cheapest, smallest and most fuel-frugal car just yet.

Instead, you may be able to find a big car that drinks like a small car.

The choices are hybrid (basically, a small petrol engine with an electric motor for assistance); diesel (expensive fuel, but goes a long way); petrol (no need to expand on this one); and LPG (it's a gas, but it is also rising in price).

Hybrid: A Toyota Prius costs $37,400, about $12,000 more than a similarly sized and equipped Toyota Corolla. But the Prius gets 4.4litres per 100km and expels only 106g of CO2 for each kilometre, while the Corolla gets 7.4 litres per 100km and emits 175g/km CO2. If you drive the Prius 15,000km a year, it will take 18 years to make up its extra price over the Corolla. But you'll feel greener.

Diesel: A diesel automatic Ford Mondeo is almost as big as a Ford Falcon. Yet, the $37,990 Mondeo gets 7.3 litres per 100km compared with the $39,990 Falcon G6 automatic's 10.5 litres per 100km. But diesel is about $1.70 a litre and petrol is $1.50 a litre, so at 15,000km a year, the Mondeo will still save you $700 each year, and about half the number of refuelling stops.

Thinking green? The Mondeo emits 197g/km CO2 and the Falcon is 252g/km CO2.

LPG: Though most motorists don't equate LPG to petrol, unfortunately it suffers the same erratic price movements. It is now in sympathy with petrol and is about 67c a litre. The Federal Government will start taxing LPG from 2011. Though cheaper, LPG is less efficient than petrol and uses up

to 30 per cent more to travel the same distance. LPG conversions get a government rebate, which makes changing over a plausible economy move for long-distance cars. Ford makes dedicated (that is, not dual-fuel) LPG Falcon models that start at $37,890. Canny motorists can buy previous model LPG Falcons at fleet auctions, though you'll be bidding against some serious taxi owners.

An LPG Falcon gets 15.5 litres per 100km compared with a petrol Falcon's 10.5 litres per 100km. The LPG Falcon costs $1400 more, so it takes 20 months for pay-back and then the LPG car promises lower future running costs. Emissions are 233g/km CO2 for the LPG and 252g/km for the petrol Falcon. Note that government rebates are not available for factory-fit LPG vehicles.

Petrol: Basically, if you're not financially blessed to buy a new car, lower your running costs by using the car less. Don't go out and sell the big family car to buy a small-engined car before doing the sums.

A 10-year-old V8 Holden, for example, is a gas-guzzler at about 16 litres per 100km. It's probably worth $10,000 as a trade-in. Buying a smaller Holden Astra, for example, to save fuel will mean you have a newer and safer car for $16,000. At $1.50 a litre, you could have bought 10,670 litres to fuel the V8 for `free' for 67,000km.

 Would you consider buying a hybrid car to beat the oil price rises?

  • On my fourth LPG vehicle in 20 years, and my mate says every time I but another one "You're crazy, the government will tax the hell out of it any day now........" I reckon I've saved the price of an entire car in that time ! Can't tow a boat, carry six people and their fishing gear and eskies over sandy tracks in any hybrid or four cyl that I know of

  • Not Carl- Why the envy?????? just join in and enjoy driving a big car for the price of a 1.3 litre petrol car.......no need to be envious and LPG will always be cheaper than petrol and even if one day the equation changes it's still many years away and that's a lot of smiling you'll have wipe off my 6 foot 4 frame......hahahahahahahahahahaha! Envy and hatred does you more damage to yourself than the person you are hating or jealous of, so wake up to your self and try to enjoy life cos it's too short!!

  • Not Carl - Geez an extra 12.5 cents excise by 2015 will really wipe the smile off our faces, we might hit $1.60 by then, what will petrol cost...$3/litre?

  • What the? I'm sure the government rebate applies but "only" $1000 for factory fitted cars, making it only $400 more! End up saving that very quickly, less than a year on your calcs. I have a EGas ute for two years and I love it. I have no idea with the cost of getting an E gas for only $400 bucks more why no one wants to get one? I'm looking at a G6 sedan on Gas next, brilliant, big car, cheap to run, comfy as, everything you need. I wouldn't look at petrol for a big car.

  • I can't wait till they slap the excise on LPG early next decade to wipe that smile off your face!

  • In our fleet we run several Toyota Prius. Our own recorded figures for the Prius are avg 5.8 - 6.2 L per 100k We don’t recommend the Prius for country use or up in hills. Another point to take into consideration is the carbon footprint from cradle to Grave (10years) is greater than many other smaller to medium sized cars on the road today. If you read the Toyota brochures the Prius runs on its petrol engine when you A. Turn on the air-conditioning or heating, B. Operate the throttle at 30% or greater, C. Operate the vehicle over 35kph.. As the batteries reduce in life the petrol motor also cuts in earlier to counteract the lessening of the batteries storage capacity. The batteries only have a life of around 10 years and cost many $thousands to replace, as they are constructed from rare earth metals cost large sums to dispose of. This is not good for the environment alone. We are currently reducing our fleet of hybrid cars until something better comes along and are moving more to LPG and Diesel powered vehicles.

  • I wish journalists did a bit more investigation into issues before they write about them and took a critical look at what is "fed" to them by large corporations. The truth is that hybrids are not the long term solution and even as a short term answer they are not all they are made out to be. Firstly their fuel consumption only really makes sense in dense urban environments. Take them on any freeway (even metro ones) and their fuel consumption advantage diminishes substantially. Secondly the environmental cost of the battery packs (making and then disposing of them) is pretty horrendous. I wish some journalist could do some digging into life time environmental impacts of hybrids. This is slightly besides the point but I heard of a hollywood celebrity who had a hybrid transported on an airplane. Talk about hypocrisy.

  • I've just bought a 10 month old BF mk11 wagon on LPG, saved thousands on depreciation and am wrapped in it because i traded a 2006 Yaris and it's actually cheaper to run than the Yaris was and no more back pain from rock hard Yaris suspension and can fit all the family easy and comfy.......can anyone tell how happy i am with my LPG wagon??????? Gota love big comfortable cars on LPG i'm never going back to petrol.....NEVER!!!!!
