Maintenance schedule

911 (996.1) — 1999–2001

At Geha Performance, we know your car's maintenance matters to you. Here is the complete maintenance schedule for your Porsche 911 (996.1), so you always know where you stand and what comes next.

Find your mileage along the top of the table. The column just before it shows what was due at the last service; the column just after, what is due at the next one. Each X marks a service that is due. The service is due at whichever comes first: the mileage or the time.

Example: at 132,000 km, the last service was the 120,000 km service and the next one is the 135,000 km service.

So-called “lifetime” fluids

For some components, such as a manual transmission or a differential, the manufacturer schedules no fluid change: it calls the oil “lifetime”. It does not say whose lifetime, and its warranty does end. Oil still ages: heat and the work of the gears break it down, mile after mile. Worn oil protects gears, synchros and bearings less well, and a transmission or differential costs far more than a fluid change.

Geha Performance therefore recommends changing these fluids at the intervals shown in the table. Where possible, each interval comes from an identical or very similar component for which a manufacturer, or the fluid's maker, publishes a change; each row's note gives the source. These rows are a Geha Performance recommendation, not the manufacturer's.

By time, regardless of mileage

Brake fluid: Every 2 years
Engine oil and filter, if the car has not had a major service: Every 2 years
Yearly inspection, without oil change, if the car is driven less than 9,000 miles (about 14,500 km) a year: Every year
Airbags and rollover protection (if equipped): After 4, 8 and 10 years, then every 2 years
Coolant: replace⁴: Every 5 years
Power steering: fluid⁴: Every 4 years

1. Porsche calls for a new oil filter every other service, at 48,000 km (next row). The Geha oil change kit always includes a filter.

2. For 1999 and 2000, Porsche calls for this replacement at 48,000 km. For 2001, at 96,000 km.

3. Tiptronic (automatic) transmission only.

4. Geha Performance recommendations for so-called “lifetime” fluids: Why we recommend this ↑

Coolant: replace. The manufacturer only has the level and freeze protection checked. Geha Performance recommends a change every 5 years, the interval published in the technical data sheet of a long-life G13-type coolant (5 years or 250,000 km).
Power steering: fluid. No manufacturer publishes a change interval for this fluid, even for a sister car. Geha Performance recommends replacing it every 4 years: this interval is Geha Performance's own choice, with no manufacturer source.

Past 300,000 km, the cycle starts over: at 315,000 km, use the 15,000 km column.

Porsche states that these intervals apply to normal driving. In dusty areas, the air filter must be checked more often and replaced if needed. On very dirty roads, the front radiators and air intakes must be cleaned regularly. Tire, clutch and brake wear and the condition of the oil depend heavily on driving habits: under these conditions, these items need more frequent service.
