When your car hesitates to start on a chilly morning, chances are your battery is on the way out. And if it completely gives up, it always seems to happen at the worst time—right before work, school drop-off, or when you're in a rush.

At Mortdale Automotive Services, we’re here to make sure you’re never caught off guard. We offer fast, affordable battery checks and replacements, so you can start every drive with confidence—no matter the weather.

Even in Mortdale’s milder winters, a cold snap can push an ageing battery over the edge. Cold weather slows down the battery’s internal chemistry, which means it delivers less power—right when your car needs more to get the engine going.

Why Your Battery Struggles When Temperatures Drop

If your battery has already been weakened by summer heat, stop-start traffic, or age, winter is often when it calls it quits.

Not sure if your battery’s still got life left in it? Watch out for these tell-tale signs:

Signs Your Battery Might Be Saying Goodbye

Power windows, radio or other electrics behaving erratically

Car starts noticeably worse on colder mornings

We stock dependable, long-lasting batteries that suit a wide range of vehicles, and we’ll make sure everything is installed properly, tested, and ready to go.

Whether you're commuting across Sydney or just heading to the shops, don’t risk a flat battery ruining your day. Come see the friendly team at Mortdale Automotive Services for a quick, no-fuss battery check.

Car Battery Checks and Replacements in Mortdale

Premium petrol is always best right? Wrong!

Think you're burning too much fuel? Did you know by filling up with the correct fuel for your car you can save money and possibly extend the life of your car?

Petrol is rated 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 lower number doesn't mean lower quality - the number determines how much heat and pressure the gasoline can resist before it detonates. A higher number can withstand more heat and a lower number less.

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 this explosion happens before the spark plug fires 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 Mortdale Automotive Services in Mortdale today.

How do I know what grade of petrol to use in my car?

To see the best fuel for your car, 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 will not make your car faster or run cleaner, it will just drain your bank account that much faster!
