Hunter drivers are being encouraged not to abandon E10 fuel in favour of the more expensive premium unleaded petrol.
A recent report shows NSW motorists have been scared off amid concerns the ethanol-based petrol causes engine damage and is not cost-efficient.
However NRMA Hunter Director, KYLE LOADES believes people are making the switch unnecessarily, saying most modern cars are made to run on E10.
"A lot of motor mechanics give out misleading information," Mr Loades said, "I'd encourage all drivers to call NRMA get the advice that their car is E10 suitable."
