Choosing The Right Fuel
Premium petrol is always best right? Wrong!
Tired of paying too much for petrol? Did you know by choosing the right fuel for your car you can save money and possibly extend the life of your car?
Petrol is graded using the Research Octane Number or RON such as 91, 95, 98, 100 or even 103. The RON number scores the fuels resistance to ‘pre-ignition’ or firing before it should due to heat from the engine.
Is a higher grade fuel better for my car?
A higher number doesn’t mean better quality - the grade signifies how much heat and pressure the petrol can resist before it detonates. Lower grade fuels detonate at lower heat and pressure than higher grades.
Why does it matter what grade of fuel I use?
Engines work by getting power from an explosion of fuel and air ignited by a spark plug. If the spark plug hasn't fired and the detonation happens early due to heat and pressure it creates a condition called “knock,” which can damage a motor and reduce power.
It's called 'knock' as that is the sound made when the fuel mix detonates too early rather than burning smoothly for fuel - which means you aren't getting the full performance from your car..
If your car is making any kind of knocking noise you should contact South East Car Care - Sorell in Sorell today.
How do I know what grade of petrol to use in my car?
To discover what fuel you need, read your car’s manual or check the label on the inside of the fuel filler door. Generally high performance vehicles need a higher octane fuel.
Remember, putting premium petrol in a car that doesn’t actually need it won’t burn cleaner or offer you more power in an engine that’s tuned for regular, it will just drain your bank account that much faster!
