Maintenance Schedule - Porsche 911 Maintenance Manual

Maintenance schedule

Scheduled maintenance
The recommended service intervals and scope of work apply
under normal driving conditions and do not take into account all
optional equipment.
Dusty areas require more frequent checking and possible
replacement of the air filter elements.
If the vehicle is driven on very dirty roads, the radiators and
cooling-air inlets in the front should be checked and cleaned
regularly.
Tire, clutch, brake pad and brake disk wear as well as the
condition of the engine oil, the transmission fluids and the brake
fluid (e.g. in the case of sporting events) are all largely
dependent on driving habits, and are also affected by adverse
operating conditions; this could mean shorter intervals between
servicing and replacement.
Time-dependent maintenance
Oil maintenance: If the mileage for scheduled oil maintenance is
not reached, oil maintenance must be performed after
1, 3, 5, 7 ... years at the latest.
Maintenance: If the mileage for scheduled maintenance is not
reached, maintenance must be performed after
2, 4, 6, 8 ... years at the latest.
Proper care and maintenance will preserve the value of your
Porsche and safeguard its functional capability.
This will also protect your right to make warranty claims.
The terms "inspect" and "check" include all associated work
such as checking the condition, adjustments, readjustments,
corrections and replenishment.
They do not include the repair, replacement or overhaul of
components or assemblies.
