Frequently asked questions

Is Triple QX Fully Synthetic A3/B4 5W-40 right for my car?

Look in your handbook or on the oil filler cap for the specification codes listed above, such as ACEA A3/B4. 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-40 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 20L pack covers a typical service with some left for top-ups. Check your handbook for the exact capacity including the filter.
