Porsche 911 oil change, in your driveway.

It depends on the year and engine — the table above lists the manufacturer's grade for each. Recent 911s most often take 0W-40. We fill with full synthetic in the specified grade.

4.1–9.4 L (4.3–9.9 qt) with a new filter, depending on engine. We fill to the dipstick and record the amount in your service record.

On the plan, when the 911's oil-life monitor reaches 10% or at 8,000 km (5,000 mi) — whichever comes later — or on Porsche's published interval. If your 911 is 2013 or newer, Aperio reads the oil-life monitor and books the visit when it's due, so you never guess.

Yes. That's the whole idea — a licensed technician comes to your driveway, workplace or a legal street spot anywhere we serve, brings the right oil and filter for your 911, and sends photos of the work.

$231.25 for a European-approval synthetic oil change on the most recent 911, plus the $20 mobile service fee — the table above shows the price for every year and engine. On the plan the oil change is included and you pay only that fee.

$280 a year. The 3.0L 6-cyl takes 8.3 L (8.8 qt). The plan includes 6 L (6.3 qt); each extra litre adds $7 a year, so this engine's plan is $280 a year. European makes are $60 a year more because they need European-approval oil — it's included. Other engines in this range are priced in the Annual plan column. One annual price, and nothing added per oil change. The plan covers every routine service on the schedule: oil and filter, rotations, seasonal swaps, tire, brake and battery inspections and air filters. The only other charge is the $20 mobile service fee per visit (first 4 visits a year; $30 after).
