Porsche maintenance schedule
Porsche's published oil-change interval: gasoline/hybrid models: oil service at every annual scheduled service — 1 year/10,000 miles, 2 years/20,000, 3 years/30,000, 4 years/40,000, 5 years/50,000 (i.e., every 10,000 miles or 1 year, whichever first). Included First Service: first scheduled service at 1 year/10,000 miles on new internal-combustion. We list the schedule rather than a dollar figure because Porsche doesn't publish service prices.
Included First Service
Term: First scheduled service at 1 year/10,000 miles on new internal-combustion (gas and hybrid) Porsches; battery-electric models get no included service
Covers: Oil service plus general maintenance at the first scheduled interval. Further years can be prepaid through the Porsche Scheduled Maintenance Plan (PSMP): Plus One through Plus Four for gas/hybrid (to 5 yr/50k), or 2/4/6-year plans for BEVs. PSMP locks in current rates for up to six years depending on model, stays with the car, can't be cancelled (unless state law says otherwise), and excludes wear items such as brake pads, rotors and tires.
