E10 Fuel

Verdict: Don’t bother

E10 petrol – a 10 per cent mix of ethanol in petrol – is a nice idea … but E10 petrol will not save you any money.

E10 petrol sounds like a smart idea - but unless you watch the price carefully you could easily get ripped offAbove: Typical ethanol marketing fluffNEED TO KNOW

Petrol is derived from crude oil, a fossil fuel. It is a chemical hydrocarbon. (Actually it’s a collection of hydrocarbons.)
Ethanol is manufactured, usually by fermentation, from plant products containing sugars and starches. Ethanol is an alcohol (actually it’s the same alcohol as the stuff in beer, wine and spirits).
When you buy fuel, you’re buying a liquid form of energy. Unfortunately, ethanol

Toll Roads

Potential Saving: $4526.40 per annum – or more

Toll roads in Australia are a complete rip-off. In particular during peak periods, Sydney’s toll roads deliver no tangible benefit to the motorist, yet toll roads cost a bomb. Traffic just grinds to a halt on the major toll roads (and the major free roads) - only the drivers stuck on the toll roads can't get off or try an alternative route. Everyone stuck on a toll road in peak-hour is trapped in a linear car park - and paying through the neck for the 'privilege'. The only group benefiting from toll roads are the companies that own them.

Incredibly, the toll road trip below – common enough for people who live in the north-west sector – costs more than $4500 annually.

We tested what happens when you slash that cost to zero using established free roads.

Mark Webber Tells: How to Drive Faster

Interested in becoming a race driver? Back in 2004, when Aussie F1 driver Mark Webber was driving for Jaguar and was in Sydney before the Australian GP, I interviewed him on this topic. Here's what he (and his engineers) said:

“Ask yourself: Would a better driver be faster in this car?” That’s what Aussie F1 driver Mark Webber does. Webber’s race engineer Pete Harrison agrees. “In F1, as many as 700 people

What's the most efficient highway travelling speed?

Driving slower will save you some fuel, and a little money. But are you prepared to cop the time penalty?

Potential Fuel Saving: Up to nine per cent

Here's a quote from the Federal Government's Green Vehicle Guide website: “High speeds result in high fuel consumption. At 110km/h your car uses up to

Should I turn off the air conditioning to save fuel?

Thinking of switching off the cool air to save money? Ridiculous!

Potential Fuel Saving: $1.75/hr, maximum

Driving with the air conditioning off in the middle of summer is intensely unpleasant, uncomfortable, irrelevant and stupid. I know this because I've done it now for two straight weeks in ambient temperatures of more than 40 degrees C. (This was one of the 'hyper-miling' techniques we used to
