Get more mileage out of your vehicle

Despite the new car sales figures for March 2022 surging to pre-pandemic levels, many South Africans are feeling the pinch of a difficult financial environment.
While 50,607 new vehicles were sold in March, led by passenger cars which accounted for 33,790 units, FNB predicts a considerable drop in South Africans’ disposable income this year due to the difficult conditions, meaning many will continue to drive the same vehicles to buy pre-owned cars out of necessity, said Hosni Adams, operations manager at Petrocam Lubricants.
“In the past, a vehicle that had reached 100 000 or 150 000 kilometres on the clock would have been considered old,” said Adams.
“However, nowadays, with improved technology and accessories, it’s not unheard of to see cars achieving more than 200 000km and still have many more miles in the tank, so to speak.
“Just recently, I witnessed a car that had well over half a million kilometres on the clock and while that is not the norm, it was in surprisingly good condition.
“The key, however, is that while this driver had enjoyed some luck along the way, he had put a great deal of care and diligence into the vehicle’s maintenance,” said Adams.
He added that there are several things anyone can do to help extend the life of a vehicle.
Engine lubrication
“For those driving newer vehicles, high-grade synthetic motor oil provides incredible protection for an engine’s components. Aside from improved efficiency and fuel consumption, these modern synthetic oils are designed to offer the perfect amount of lubrication.
“Always consult the owner’s manual for the correct viscosity, and ensure the lubrication is changed at regular intervals. Yes, synthetics cost more, but the payoff is even greater in how it protects engines from mechanical wear”.
“For those with older vehicles, a high-quality synthetic blend or mineral oil is also designed to protect the engine, but the same rules apply. Always use the correct oil according to the manufacturer’s recommendations and ensure it is changed at the correct intervals,” said Adams.
Gearbox, differential, bearings and more
These components also work under extreme conditions and temperatures.
An automatic transmission, for example, works with an interplay between clutches and bands and other components, and unnecessary wear and tear can lead to premature failure.
Those who want their cars to last longer should ensure that their gearboxes are serviced and that the oils are replaced, at the correct intervals, said Adams.
Always remember that there are more moving parts than just the engine, and this includes the entire drive chain, ball joints and bearings, keep an eye on their wear and tear and service and replace them when necessary.
“Is your front-wheel-drive car making a clicking noise when turning? It’s time to check the CV joints. Especially those that drive older vehicles, have your mechanic check all the moving parts and ensure they have the correct oils and greases where applicable.”
Filters
Adams said that while many of us know that the air filter gets changed along with spark plugs in minor services, not everyone is aware that there are oil filters and fuel filters.
These also need to be checked.
Cooling system
“When last did you or your mechanic give your radiator and hoses a thorough check?” asked Adams, adding that every few years the entire cooling system should be flushed out, and important components replaced.
If a thermostat, for example, is not working properly, and an engine overheats, the damage will be far more costly and severe than staying ahead of the curve with regular checks.
Tyres
There’s more to just tyre tread depth, said Adams.
If the tyres are meant to be rotated, then this needs to happen for equal wear.
If the tyres are wearing in a particular pattern, is it indicative of something that needs replacing on the suspension?
Beyond that, said Adams, there is little joy to be had in thinking there is enough tread on an old tyre that has been in harsh conditions as the rubber may well have degraded, making for an unsafe tyre.
Sensors
As vehicles age, sensors and the wiring harness may age and, in some instances, start malfunctioning which can have a knock-on effect on the rest of the engine.
Ask your mechanic to check your wiring harness, said Adams, as well as sensors such as the Mass Air Flow metre, throttle position sponsor, oxygen sensor, fuel pump relay, and coolant temperature sensor, among others.
“Don’t be tempted to just do the minimum. The key to having a vehicle do many kilos is staying on top of the condition of all its important components,” said Adams.
Belts and chains
“A cambelt breaking while driving can have catastrophic consequences for valves and leave you stranded,” said Adams.
Be aware that your vehicle has important belts and in some cases chains that need to be in perfect working order.
Be aware of this and make sure to ask your mechanic to check them.
If it is suggested you change a cambelt, for example, then do it.
“Of course, there are other important things too, such as ensuring the car’s battery is still functioning properly and that the terminals are always clean and tight.
“But the key is to start seeing your car as the sum of its parts and keeping ahead of the curve in the maintenance and lubrication of those parts. That’s how you get the most mileage out of the car that’s served you so well in the past,” he said.
