Incorrect petrol used in car
Most cars in Australia run on low octane 91 RON. The high octane equivalent, 95 and 98, are getting more popular. While using a high-octane in a car that needs 91 will only hurt your pocket, using 91 in a car that needs 95 or 98 can cause significant damage.
- A low octane car runs better on a higher-octane fuel better than if the situation is reversed.
- Some cars requiring high-octane fuels can still operate on 91, however there is a risk your car will suffer engine damage
- Reduced power, lower fuel economy and engine damage are signs of a low-octane fuel being used incorrectly
- Ways to fix a car that requires a high-octane fuel includes:
- Draining incorrect petrol
- Flushing fuel through the tank
- Engine repairs
