How to extend the lifespan of your car

For most Aussies, the largest purchase we’ll ever make (beyond a house) is a car.

So, it’s only normal to want to care for our vehicles to help them live as long as possible.

According to UK company CarFinance 247, certain triggers could affect the longevity of your vehicle, so let’s run through what they are and how to combat them, to best extend the lifespan of your car.

Not driving your car for long periods

Going on a holiday and leaving your car behind for an extended period can affect the battery, which will lose charge when the vehicle isn’t being used, says Louis Rix from CarFinance 247.

“On average, a standard car battery can hold its charge for around four weeks, but this can vary depending on the climate, how old the battery is, and the make and model of your car. We always recommend driving your car every two to three weeks to help keep it in running condition,” says Rix. 

“If you’re going on holiday for several weeks, make sure to remember to give your vehicle a drive round for 15-30 minutes before you go, to help the battery stay in good condition. If you have an electric car, you can leave this for an extended period of time, unplugged. EV batteries are large and can hold charge for a long time.”

Hot weather

Hot temperatures can also negatively impact your car, where fluids (coolant, oil, etc) in your car operate at a higher temperature, increasing the risk of your engine overheating.

Rix says a warning light should appear on the temperature light or gauge if your engine is overheating but other signs include a ticking sound coming from the engine, coolant on the ground, a hot bonnet, or reduced engine power. 

“If you suspect your engine is overheating, do not drive your car. Pull over if your temperature gauge starts to tick up too high. While this typically shouldn’t be a problem on well-maintained modern cars, it could be a problem for older vehicles.”

Tree sap and pollen

Meanwhile, tree sap – particularly in the summer months – could cause other problems.

“If you park under a tree in summer, you might notice a sticky residue on your car. This is caused by tree sap droplets,” says Rix.

“If tree sap is left on your car, the sap can harden, causing paint damage. To prevent this, remove it as soon as possible with lots of hot water and a soapy solution. Use a good windscreen wash to clear the windscreen from sap too.”

Storms and heavy downpours of rain

Rix says heavy rain and floods can be a risk to your car’s health.

Avoid driving through deep puddles of standing water, which could get sucked into the engine, causing breakdowns and/or long-term damage to your car’s electrical system.

“If you do drive through a flood, check your brakes as they can become clogged after driving through water. To test, apply them on and off while moving to help dry them.”

Not preparing for long car journeys

“Your car is designed to drive both long and short distances and as long as it’s properly maintained and serviced regularly, it should be fine,” says Rix.

However, if you have an older vehicle, longer journeys could present more of a challenge, particularly for those who’ve failed to prepare.

“Ahead of a long car journey, always make sure to check your tyres and their pressure. Look over the sidewalls for any cracks or cuts, as this could lead to a blowout,” says Rix.

“Make sure you have a spare wheel and ensure this is inflated to the correct pressure, in case you need it. Before setting off, we always advise motorists to check oil levels too. If your oil is low, this can cause your engine to overheat.”

Off-road journeys

Aussies love the great outdoors, especially when there’s a bit of 4x4 bush-bashing involved.

But Rix says those looking to explore areas off the beaten track might want to keep a few things in mind.

“Be cautious if you’re driving off the beaten track or in rural areas, as the roads can often be uneven, which can cause complications for your car. If you hit a pothole, particularly at speed, this can damage your exhaust pipe or the catalytic converter under your car - as well as its suspension system.”

A big hit to the suspension could lead to a wheel misalignment, tyre punctures, and even bent rims.

“To help avoid this, make sure to drive over any bumps slowly - or around them if you can. If possible, try not to slam the brakes on when you spot a bump ahead either as braking harshly can shift the car’s weight to the front which can affect the suspension.”
