What You’ll Need
- Correct engine oil (grade and specification for your car)
- New oil filter
- Drain pan (at least 6L capacity)
- Socket set (usually 13mm or 17mm for the drain plug)
- Oil filter wrench or strap wrench
- Jack and axle stands (or ramps)
- Gloves, rags, and old newspaper
- New drain plug washer (copper or aluminium)
Step-by-Step
- Warm the engine for 5 minutes (warm oil drains faster and carries more contaminants).
- Safely raise the front of the car and secure on axle stands.
- Place the drain pan under the sump plug.
- Remove the oil filler cap (top of engine) to aid draining.
- Undo the sump plug and let the oil drain fully (15-20 minutes).
- While draining, remove the old oil filter using the filter wrench.
- Lightly oil the rubber seal on the new filter and screw it on hand-tight.
- Refit the sump plug with a new washer and tighten to spec (don’t over-tighten).
- Lower the car and add new oil through the filler cap.
- Add oil to 80% of the total capacity, then check the dipstick and top up gradually.
- Start the engine and run for 2 minutes. Check under the car for leaks.
- Recheck the oil level after the engine has been off for 5 minutes.
Oil Disposal
Used engine oil is classified as hazardous waste. Never pour it down a drain. Take it to your local recycling centre or Halfords store (many accept used oil for free). Keep it in a sealed container for transport.
Frequently Asked Questions
How long does a DIY oil change take?
30-45 minutes for a first-timer, 20 minutes once you’re experienced. The oil needs 15-20 minutes to drain fully.
Do I need to change the oil filter every time?
Yes. Always change the filter with every oil change. A new oil filter costs £5-15 and ensures clean oil stays clean.
What if I strip the sump plug thread?
This is fixable with a helicoil or oversize plug kit (£10-20). To prevent it, always use a torque wrench and never cross-thread the plug.
