Step by step
- Find the right oilCheck the viscosity (for example 5W-30) and approval code in the manual. The approval is often more important than the brand.
- Check the level firstPark on level ground, wait and read the dipstick or display.
- Open the oil filler capIt is on top of the engine and often marked with an oil can symbol. Do not confuse it with the coolant or brake fluid caps.Never open the coolant cap on a hot engine.
- Add a small amountPour in about half of what you think is needed. On many cars the gap between minimum and maximum is around one litre, but check the manual.
- Wait and recheckGive the oil a minute to run down, then check again. Repeat until the level is near, but not above, the maximum.
- Close the cap and clean upMake sure the cap is tight and wipe any spilled oil, which can smoke on hot parts.
When to go to a workshop
Have the car checked if it needs oil often, if you see blue smoke or oil leaks, or if the oil level warning returns soon after topping up.
If the oil change is overdue, topping up is only a short-term fix: book a service.
Questions about How To Top Up Engine Oil
Can I mix different oil brands?
Usually yes, as long as the viscosity and approval match. Mixing is better than driving with too little oil.
Can I use any 5W-30?
Not always. Many engines require a specific manufacturer approval, especially diesels with particulate filters.
