How to Change Engine Oil

It is important to change your car’s oil frequently to prevent premature engine wear. As engine oil gets older, or if you have been driving in very hot and/or dusty conditions, oil can become contaminated. Generally oil changes under normal conditions are required between 5,000 and 10,000km. Check your vehicle’s user manual for further information and recommendations for scheduled oil changes.

What you need to get the job done

  1. Drain Pan
  2. 5L bottle of oil, plus 1L for top ups
  3. Rag for clean up
  4. Euca hand cleaner or similar
  5. Funnel
  6. Engine Oil Flush (optional)
  7. Creeper (optional)


Repco recommends using an Engine Oil Flush before changing your Engine Oil to assist in ridding the engine of potentially damaging contaminants. This will help to clean and remove sludge, dirt and varnish, plus keep the oil strainer clean and extending engine life.

Add 1 bottle for up to 5 litres of engine oil before your oil change, and allow the engine to idle for up to 10 minutes (maximum) whilst stationery.

Follow these simple steps

  1. Position drain pan under the drain plug and remove the plug to let the oil drain. Clean around the plug opening when oil has finished draining, and replace the drain plug.
  2. Position the oil pan under the filter, using an oil filter wrench unscrew the old filter.
  3. Wipe the area with a clean rag, ensuring also that the rubber seal from the older filter is not adhered to the engine.
  4. Using some new oil, coat the rubber seal of the new filter
  5. Screw the new filter into place until tight, by hand should suffice.
  6. Now remove the oil filter cap on top of the engine and place a funnel in the opening.
  7. Pour in the new oil, checking your manual for the right oil capacity and type.
  8. Replace the cap, check around plug and filter for leaks, and wipe away any excess oil.
  9. Run the engine for approximately 10 minutes and check the dipstick. Add more oil if required.
