Why does my car use so much petrol?
Noticing your car burning through petrol faster than it should? Here are the most common causes and what to do about each one.


Selling a car in New South Wales used to follow a predictable, if exhausting, path. You would wash the car, park it on the curb with a sign, or list it online and hope for the best. Today, the digital marketplace has made things faster but significantly more complicated.
While many owners start by looking up how to sell a car privately to maximise their return, they often find that the "extra" profit is quickly swallowed by the sheer volume of labour required.
If you are a Sydney car owner, you are likely balancing a busy schedule with the desire for a fair deal. This guide breaks down the reality of the private sale process and introduces a streamlined alternative that prioritizes your safety and your time.
When you decide to manage a sale yourself, you aren't just selling a car. You are taking on the roles of a professional photographer, a digital marketer, a customer service representative, and a high-stakes negotiator.
Before your car is even ready for a listing, it needs to be "showroom ready." This involves more than a quick soap and water scrub. Most successful private sellers spend hundreds of dollars on professional detailing or several weekends doing it themselves. You need to capture high quality photos from every angle, ensuring the Sydney sun doesn't create too much glare.
Once your ad is live, the influx of messages can be overwhelming. You will likely encounter "lowballers" offering half your asking price before even seeing the car. Filtering through genuine buyers versus time-wasters is a secondary job in itself.
Safety is a primary concern for many sellers in Greater Sydney. Learning how to sell a car privately means accepting the risk of inviting strangers to your home for inspections and test drives.
Furthermore, the paperwork in NSW requires precision. You must provide a clear title, ensure the registration transfer is handled correctly, and manage the risk of fraudulent payments. When selling a car privately vs a dealer, the dealer takes on all this legal and safety risk, whereas the private seller carries it all.
Before you commit to any path, you need to know what your car is actually worth in the current market. A car valuation that Sydney residents can trust should be based on real time data, not just an emotional attachment to the car.
Local market conditions change rapidly. Fuel prices, the availability of new models, and even the time of year can shift the value of your car by thousands of dollars. Getting an objective, data-driven figure gives you a benchmark. If the gap between a private sale price and a professional offer is slim, the "hustle" of a private sale becomes much harder to justify.
The main argument for the private route is usually the price. However, when you calculate your hourly rate and the cost of listing fees and cleaning, the "profit" often evaporates.
A dealership or a specialised buying service provides a "set and forget" experience. While a traditional dealer might offer a lower trade-in price to protect their margins on a new sale, a dedicated buying service like Carma operates differently. By focusing on quality and transparency, the process is designed to be fair for both parties without the back and forth haggling that defines the private market.
One of the biggest hurdles in any automotive transaction is trust. For decades, the NRMA has been the gold standard for NSW motorists. Carma has built a strategic partnership with the NRMA to ensure that the process of selling your car is backed by a name you already know and respect.
This partnership means the standards for car inspection and pricing are rigorous and fair. You are not dealing with a mysterious online entity, but a service integrated with Australia's most trusted motoring organisation. This level of credibility is something you simply cannot replicate when figuring out how to sell a car privately.
One of the most stressful moments of a private sale is the exchange of funds. Bank cheques can be forged, and cash is a safety risk. Even digital transfers can be recalled in some fraud scenarios if the buyer is acting in bad faith.
Professional buyers provide the security of an instant bank transfer. This means the money is cleared and visible in your account before you even hand over the keys. For most Sydney owners, the peace of mind that comes with a guaranteed, secure payment outweighs the potential of a few extra dollars from a private buyer who might cause a headache later.

If you still choose to go the private route, you must be meticulous. Document every service, keep every receipt, and be prepared for a process that can take weeks or even months. You will need to manage the "Notice of Disposal" with Service NSW immediately to ensure you are not held liable for any fines the new owner might pick up.
However, if you value your weekends and want to avoid the risks of the open market, there is a faster way to achieve a professional result.
