Key benefits

  • Fully synthetic base oil keeps its viscosity stable from cold starts to sustained high temperatures.
  • ACEA C3: a low-SAPS specification that protects diesel particulate filters and catalysts while keeping a higher film strength, used by BMW, Mercedes-Benz, Volkswagen Group and GM.
  • API SP: the current API petrol engine category, with added protection against low-speed pre-ignition in turbocharged engines.

Frequently asked questions

Is Castrol Edge M 5W-30 right for my car?

Look in your handbook or on the oil filler cap for the specification codes listed above, such as BMW Longlife-04. If your vehicle lists one of them, this oil meets the requirement. If you are unsure, send us your registration number and we will confirm the correct grade.

What does 5W-30 mean?

The first number (5W) describes how easily the oil flows when cold, so a lower number means easier cold starts. The second number describes the oil's thickness at normal running temperature. Always use the grade your manufacturer specifies.

How much oil will I need?

Most petrol and diesel cars take between 4 and 6 litres for a full oil change, so a 4L pack covers a typical service with some left for top-ups. Check your handbook for the exact capacity including the filter.

Supplied sealed in the manufacturer's original packaging and dispatched from the UK by Nitroma Lubricants.
