Frequently Asked Questions

How much oil does a 2.0 L petrol engine need?

A 2.0 L 4-cylinder petrol engine typically takes 4.0–4.5 L with a new oil filter. The filter itself holds 0.25–0.35 L of oil. Always refer to the owner's manual for the exact specification as turbo engines and some designs vary.

Do I need more oil if I change the filter?

Yes. A new oil filter holds 0.25–0.5 L of oil (more for larger diesel filters). When you install a new filter, add this volume on top of the sump capacity. This calculator includes the filter allowance in its total capacity estimate.

How often should engine oil be changed in NZ?

Most modern vehicles specify oil changes every 10,000–15,000 km or 12 months, whichever comes first. Older vehicles and those doing short trips or dusty conditions may need changes every 5,000 km. Always follow the manufacturer's service schedule.
