Step-by-step: changing your car’s oil at home
Changing engine oil at home is one of the most practical maintenance jobs for an Australian driver. With basic tools, the correct lubricant and a safe place to work, you can refresh the oil, replace the filter and learn more about the condition of your vehicle.
The job suits many cars, utes and four-wheel drives, although the exact procedure varies. A compact hatchback in Melbourne may need a different oil grade and capacity from a diesel ute used around Brisbane or a heavily loaded four-wheel drive travelling through regional New South Wales. The owner’s manual remains the final authority.
A clear video can make unfamiliar steps easier to follow, especially when locating the sump plug or identifying the filter housing. Lajsiab’s video archive collects practical clips alongside motoring and entertainment material, so it can be useful when you want to compare a visual demonstration with your vehicle handbook.
Allow enough time for the engine to cool, gather every item before lifting the vehicle and never rush the safety checks. A careful oil service should leave the car level, leak-free and ready for a responsible disposal of the old oil.
Prepare the car and equipment
Park on a firm, level surface away from traffic. A concrete driveway is preferable to loose gravel, and shade is helpful in hot Queensland or Western Australian weather. Engage the handbrake, select Park in an automatic or first gear in a manual, and place wheel chocks behind the wheels that remain on the ground.
You will generally need the manufacturer-specified engine oil, a compatible oil filter, a drain pan, a socket or ring spanner, a filter wrench, a funnel, gloves, rags and a new sump-plug washer if the vehicle uses one. A trolley jack may lift the car, but it must be supported by correctly rated axle stands placed at the approved jacking points. Never work beneath a vehicle held only by a jack.
Check the service information for oil viscosity, specification and quantity. Australian retailers such as Repco, Supercheap Auto and Autobarn stock common grades, but the cheapest bottle is not necessarily suitable. A modern turbocharged petrol engine, diesel with a particulate filter and older naturally aspirated engine can all require different formulations. Buy slightly more than the stated capacity so you can adjust the level accurately.
Before beginning, confirm that the filter is accessible and that the drain plug can be loosened. If the plug is rounded, badly corroded or extremely tight, stop rather than forcing it. A damaged sump or broken plug can turn a routine service into an expensive repair.
Drain the old engine oil safely
Run the engine for only a few minutes to warm the oil. Warm lubricant drains more readily, but hot oil can cause serious burns, so do not work immediately after a long drive. Switch off the engine, wait briefly, then raise and support the vehicle if clearance is needed. Position the drain pan under the sump plug, allowing for oil to travel sideways as the plug comes free.
Loosen the plug anti-clockwise with the correct socket, keeping your hand and forearm out of the likely flow path. Finish removing it by hand and let the oil drain fully. The initial stream may be forceful, and the pan should be large enough to catch the entire quantity. Many Australian cars hold between four and six litres, while some larger diesels take considerably more.
Inspect the removed plug and washer. Fine metallic paste on a magnetic plug can be normal, but visible chips, flakes or a sudden change in the oil’s appearance deserves professional attention. Milky oil may indicate coolant contamination, while a strong fuel smell can point to a running or injection problem. Do not simply refill and ignore warning signs.
Once the flow becomes a slow drip, clean the sealing surface around the sump. Fit the new washer where required and start the plug by hand to avoid cross-threading. Tighten it to the torque listed in the service manual. Guessing with excessive force can strip an aluminium sump, while leaving it loose may cause a leak.
| Task | What to check | Common mistake |
|---|---|---|
| Warm the engine | Oil is warm, not dangerously hot | Starting work straight after a long trip |
| Position the drain pan | It covers the plug and expected flow | Using a container that is too small |
| Remove the sump plug | Correct socket and steady hand pressure | Rounding the plug with an adjustable spanner |
| Fit the replacement washer | Washer matches the vehicle and sits flat | Reusing a crushed sealing washer |
| Tighten the plug | Use the specified torque where available | Overtightening or leaving it loose |
Replace the filter and refill the engine
Move the drain pan beneath the oil filter before loosening it, because the filter will contain old oil. Spin-on filters usually loosen anti-clockwise when viewed from below, while cartridge systems have a removable cap and a separate element. Use a filter wrench only when necessary; crushing a thin filter can make removal harder.
Before fitting the new filter, compare it with the old one. Check the thread, diameter, seal and part number. Smear a thin film of fresh oil over the rubber gasket on a spin-on filter. This helps the seal seat correctly and makes the next removal easier. Screw it on by hand until the gasket contacts its mounting surface, then tighten according to the filter instructions—often a fraction of a turn rather than using a wrench to force it tight.
For a cartridge filter, replace every supplied O-ring in the correct groove. An O-ring fitted in the wrong position can leak or become pinched. Wipe the housing clean, install the new element as directed and tighten the cap to the specified torque.
Lower the vehicle only when it is safe to do so, then add most of the required oil through the filler cap using a funnel. Wait a minute for it to settle, check the dipstick, and add small amounts until the level reaches the appropriate mark. Do not pour in the full listed capacity automatically, because the stated figure may include a completely dry engine or vary slightly by filter type.
Check for leaks and dispose of used oil
Start the engine and let it idle for around 30 seconds. Watch the oil-pressure warning light; it should go out promptly. Switch the engine off, wait several minutes and inspect the filter and sump plug for seepage. A clean piece of cardboard placed beneath the car can make small drips easier to identify.
Recheck the dipstick on level ground. The reading should sit between the minimum and maximum marks, preferably near the upper mark without going over it. Excess oil can cause foaming, crankcase pressure and other mechanical problems. If the warning light remains on, stop the engine immediately and investigate rather than driving to a workshop.
Record the date, odometer reading, oil grade, quantity and filter part number. Australian service intervals vary considerably: short trips, towing, dusty rural roads and stop-start traffic in Sydney or Perth can place greater demands on oil than steady highway travel. Follow the severe-use schedule in the handbook if it applies.
Used engine oil must never go into a drain, garden soil or household rubbish. Pour it into a sealed, clearly labelled container and take it to a council household chemical collection point, transfer station or participating automotive retailer. Programs and limits differ between councils, so check the local rules before arriving. Keep the old filter upright in a tray until it has drained, then dispose of it through an approved recycling or waste channel.
When looking for maintenance information online, stay alert to unrelated pages and unclear downloads. A link such as external website should be treated separately from your vehicle research, particularly if it asks for personal details, software installation or payment. Reliable instructions should identify the car, engine and required procedure clearly.
Build a repeatable maintenance routine
An oil change is more useful when it forms part of a broader inspection. While the vehicle is raised, look for damaged boots, loose undertrays, oil stains, worn belts and unusual corrosion. Check tyre condition and pressure when the car is back on the ground, and inspect the coolant, brake-fluid and windscreen-washer levels.
Keep a simple log in the glovebox or on your phone. Note whether the old oil was unusually dark, gritty or thin, and record any leaks that appeared after the service. Dark oil alone does not automatically mean failure; detergent additives are designed to suspend contaminants. A rapid level drop or repeated low-oil warning is more significant.
Use video as a visual aid, not as a substitute for vehicle-specific specifications. A general demonstration can show the order of operations, while the handbook supplies the correct oil approval, tightening torque and refill capacity. For a more focused visual reference, this oil change clip can help you recognise the basic sequence before working on your own car.
- Choose the oil grade and specification listed for your exact engine.
- Support the vehicle with rated stands on firm, level ground.
- Replace the filter and sump-plug washer when required.
- Check the level and inspect for leaks before driving.
- Store and recycle used oil through an approved Australian facility.
A home oil service should finish with a short test drive and another inspection on level ground. Keep the receipt for the oil and filter, retain the service record and follow the next interval recommended for your driving conditions. Set aside a safe afternoon, prepare the correct supplies and carry out each step methodically so your car is ready for its next trip.
