From the local paper: A Ballarat mother of three wants to warn the public about the hidden risk of pumping contaminated petrol into vehicles with damaging and expensive results. Ballarat Holden has confirmed the petrol in her tank contained excessive amounts of water, which led to corrosion in the fuel pump. The businesswoman, who wanted to be known only as Lyn, said she had been left with a $3000 bill at Christmas time after getting petrol from her regular outlet. Lyn has been dealing with insurance companies but is finding it difficult to have her claim approved despite tests proving the fuel contained large amounts of water. "It's put us out of pocket,"she said. "It's $3000 we didn't have at Christmas ... we should have been able to spend that on the kids." Lyn said there were other families in the same situation and she felt compelled to speak out and highlight the problem. It is impossible for car owners to see the tainted petrol when they are pumping it into their car. Ballarat Holden had been servicing the car and sent the damaged parts away for testing. Ballarat Holden general manager Siggy Haas said tests clearly showed the fuel in the car was "contaminated and clearly had excessive amounts of water"and was outside the acceptable water limits. "Holden has come back to us with engineering proof that the resultant damage is not product related. It's fuel contamination which has caused the problem with (her) car,"he said. However, he said the contamination could have occurred in several ways with water making its way into the holding tanks. "It's very, very hard to trace back,"Mr Haas said. "There's a lot of influencing factors that can do it. "Some of them are not in the control of fuel companies." Mr Haas said he had seen this type of petrol problem periodically during his time in the industry, including stints with BMW and Porsche, with similarly damaging results to vehicles. "Fuel contamination is not new,"he said. "When we see them we tend to get a few in a row. It's unfortunate for the owner." Mr Haas said Lyn was fortunate because she bought the fuel at a regular service station and as a company car there was clear proof of purchase. Lyn said the ordeal began on Tuesday, October 25, last year, and she knew of two other couples who had been affected at the same time. "Ever since this happened I have had nothing but a nightmare,"Lyn said.
