The Environmental Case for Regular Servicing

Emissions and Engine Efficiency

An engine running on old, degraded oil, a clogged air filter, or a failing oxygen sensor doesn't just use more fuel — it burns that fuel less cleanly, producing more emissions per kilometre than a properly maintained equivalent.

The Catalytic Converter's Role

The catalytic converter reduces harmful emissions from the exhaust, but it relies on the engine running correctly to do its job — a genuine misfire (the kind a flashing check engine light warns about) can overwhelm and permanently damage it, turning a temporary problem into a lasting emissions issue.

Tyre Pressure and Rolling Resistance

Under-inflated tyres increase fuel consumption for the same distance travelled — a straightforward, direct emissions cost that costs nothing to fix, just a few minutes with a gauge.

Extending Vehicle Lifespan

The most significant environmental cost of car ownership is often the manufacturing footprint of the vehicle itself — a well-maintained car that lasts years longer before needing replacement has a real environmental advantage over one retired early due to neglect.
