Is it possible to cut the cost of driving?

Yes, the price of petrol and diesel is going through the roof but there are many ways to help reduce the cost of filling the tank, writes John Hearne

Last July, the national average price of petrol was 153.9c. Diesel cost 143.5c. Last month, the equivalent figures were 213.2c and 205c respectively. That’s a 75% increase in the price of petrol and a 70% rise on the price of diesel.
