Changing your own oil is one of the most satisfying jobs you can tackle in the driveway. It costs a fraction of a workshop visit, it teaches you a little more about how your engine actually works, and once you know the process, it only takes around an hour from start to finish. This guide walks Northern Beaches drivers through everything needed to change engine oil safely at home, from the tools to gather beforehand to the warning signs that tell you the job is better left to a professional. If you would rather skip the driveway altogether, the team at NM Performance Automotive can take care of your oil change or a full logbook service at our Mona Vale workshop.
Tools & Materials You’ll Need
Before you start, lay everything out so you are not searching for a socket halfway through the job with oil dripping onto the driveway. You will need an oil filter wrench, a socket set that matches your drain plug, a drain pan large enough to catch as much oil as the car takes, a funnel, a jack and a pair of axle stands, disposable gloves, and a stack of rags.
You will also need a new oil filter, sump plug washer and the correct grade of oil for your engine, which is listed in your owner’s manual or on the oil cap itself. Using the wrong viscosity can affect fuel economy and long-term engine wear, so it pays to double-check before you buy. Our guide on why changing engine oil is essential covers this in more detail, and Choice has an independent comparison of engine oils and filters worth reading before you commit to a brand.
Step-by-Step Oil Change Process
Once you have your tools and the right oil ready, the job itself follows a straightforward sequence. Work through each stage in order and take your time, particularly the first few times you do it.
Warm the Engine
Run the engine for around five minutes before you start draining the oil. Warm oil flows more freely and carries more of the sediment and debris out with it, which means a cleaner result overall. You do not need the engine fully hot, just warm enough that the oil has loosened up, and be careful when working underneath the car afterwards since some components will still be warm to the touch.
Drain the Old Oil
Lift the car safely using a jack and support it properly on axle stands rather than relying on the jack alone. Slide the drain pan underneath the sump, then loosen the drain plug with your socket set and remove it by hand. Let the oil drain completely, which usually takes several minutes, and always replace the drain plug washer.
Replace the Filter
With the oil fully drained, refit the plug and turn your attention to the filter. Use the oil filter wrench to remove the old one, then wipe the mounting surface clean before fitting the new filter. Apply a thin layer of fresh oil to the new filter’s rubber gasket, which helps it seal properly, and tighten it by hand rather than with tools to avoid over-tightening.
Add New Oil & Check the Level
Using the funnel, pour in the correct quantity of new oil as specified in your owner’s manual, then start the engine and let it run for a minute before checking for leaks around the plug and filter. Turn the engine off, wait a few minutes for the oil to settle, then check the level on the dipstick and top up as needed until it sits between the minimum and maximum marks.
How Often Should You Change Your Oil?
Most manufacturers recommend an oil change every 8,000 to 10,000 kilometres, or every six to twelve months, whichever comes first. That said, the right interval depends on your specific vehicle, the type of oil used, and how the car is driven. Frequent short trips, towing, dusty conditions, or stop-start city driving all place extra strain on engine oil and can shorten the recommended interval. NRMA publishes helpful general car care guidance if you want a second opinion on maintenance timing for your make and model. Sticking to your logbook service schedule is also the simplest way to protect your new car warranty while keeping the engine running the way it should.
Signs You Waited Too Long
Engine oil naturally darkens with use, but if it looks gritty, smells burnt, or has dropped noticeably on the dipstick, it is well past due for a change. Other warning signs include the oil pressure light appearing on the dashboard, a knocking or ticking noise from the engine, and a noticeable drop in performance or fuel economy. None of these should be ignored, since running an engine on old or low oil accelerates wear on internal components that are expensive to replace. If you notice any of these signs, it is worth getting the car looked at sooner rather than later.
When to Leave It to the Professionals
DIY oil changes are not for every driver or every vehicle. Some engine bays are tightly packed and make the drain plug or filter difficult to reach safely, and several European models require an electronic service reset once the oil has been changed, without which the dashboard will keep flagging an overdue service. Safe disposal of used oil is another consideration, since it cannot simply be poured down a drain or left in general waste. If any of that sounds like more hassle than it is worth, our team handles everyday servicing through general car servicing as well as specialist work through our Volkswagen Group service, and you can browse our full range of services to see everything covered at our Mona Vale workshop. Service NSW also has more detail on logbook servicing requirements if you are weighing up your options.
