How to change engine oil and filter
Regular oil changes are the single most important maintenance job for engine life. With the right oil and a few tools it is a straightforward DIY job.
Tools
- Wrench or socket for the drain plug
- Oil filter wrench
- Drain pan
- Funnel
- Jack and axle stands or ramps
- Gloves and rags
Parts & materials
- Engine oil of the grade and specification in your owner's manual
- New oil filter
- New drain plug washer (often single-use)
Step by step
- Run the engine for a few minutes so the oil flows easily, then switch off. Hot oil can burn: let it cool for a few minutes.
- Raise the car safely on ramps or a jack with axle stands on firm, level ground.
- Place the drain pan under the drain plug, remove the plug and let the oil drain completely.
- Fit the new washer and refit the drain plug. Tighten to the specified torque; do not over-tighten into an aluminium sump.
- Remove the old filter. Make sure the old rubber seal came off with it.
- Lightly oil the new filter's seal and fit it hand-tight plus the amount stated on the filter (usually about three quarters of a turn). For cartridge filters, follow the housing's torque.
- Lower the car to level ground. Fill with the specified quantity of oil, a little less than the full amount at first.
- Start the engine, run it for a minute and check for leaks. Switch off, wait a few minutes, check the dipstick and top up to the full mark.
- Reset the service indicator if the car has one. Take the old oil to a recycling point.
Safety: Never work under a car supported only by a jack.
Safety: Used engine oil is harmful: wear gloves and dispose of it properly.
