Frequently asked questions
Is Castrol Power1 4T 10W-40 right for my car?
Look in your handbook or on the oil filler cap for the specification codes listed above, such as API SN. 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 10W-40 mean?
The first number (10W) 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 1L pack is ideal for top-ups between services. Check your handbook for the exact capacity including the filter.
