Quick answer: Park on level ground and wait 5 minutes after switching off. Pull the dipstick out, wipe it clean, push it fully back in, pull it out again and read where the oil film sits: it should be between the MIN and MAX marks. If it is below MIN, add oil 250 ml at a time and re-check after each top-up. If your car has no dipstick, the level is shown on the dashboard or infotainment menu (see Electronic Oil Level below).
When to Check
Check your oil level at least once a month, and always before a long journey. Some cars consume a small amount of oil between services — this is normal, especially for turbocharged engines.
Dipstick Method
- Park on level ground and wait 5 minutes after turning off the engine.
- Open the bonnet and locate the dipstick (usually a yellow or orange pull handle).
- Pull the dipstick out and wipe it clean with a cloth or paper towel.
- Re-insert the dipstick fully, then pull it out again.
- Check where the oil film reaches — it should be between the MIN and MAX marks.
- If below MIN, add oil in 250ml increments, checking between each addition.
Electronic Oil Level
Many modern cars (BMW, Mercedes, VW) have removed the dipstick in favour of electronic oil level sensors. Check via your dashboard display: usually Settings → Vehicle Status → Oil Level. The car must be on level ground with the engine warm for an accurate reading.
Frequently Asked Questions
What happens if oil is too low?
Low oil causes increased friction, overheating, and accelerated engine wear. Critically low oil can cause catastrophic engine failure within minutes.
Can I have too much oil?
Yes — overfilling can damage seals, cause foaming, and lead to catalytic converter damage. Always add oil gradually and check between additions.
What colour should engine oil be?
Fresh oil is honey-coloured. Used oil darkens to brown/black over time — this is normal. Milky or foamy oil indicates coolant contamination and needs immediate investigation.

How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
