Questions

TyresWhy does my 997 handbook give two sets of tyre pressures?

Porsche gives a part-load figure for up to two people without luggage and a higher full-load figure for two or more people with luggage. On most 997s the full-load figure is 2.5 bar front and 3.0 bar rear. The 18-inch 997.1 Carrera uses that figure at all loads, and the GT3, GT3 RS, GT2 and GT2 RS have a single, much lower figure instead.

Source: Porsche 911 Carrera owner's manual (MY2007 and MY2010, US edition), Tire pressures for cold tires; Porsche Manufacturer's Certificates 77/21, 86/21 and 89/21.

OilDoes a 997.2 take less oil than a 997.1?

Yes. Porsche's handbooks give about 8.25 litres (3.6) or 8.5 litres (3.8) for an oil and filter change on a 997.1 Carrera, but about 7.5 litres on the direct-injection 997.2 Carrera. Both take an A40 oil. The level check differs too: a 997.1 reads its level on the on-board computer with the engine off and the ignition on, while a 997.2 reads it with the engine warm and idling. On either, add no more than 0.5 litre at a time.

Source: Porsche 911 Carrera owner's manual (MY2007 and MY2010, US edition), Capacities and Oil level measurement.

TyresWhere do I find the correct tyre pressures for my car?

On the tyre pressure label on the car itself, in the driver's door frame, and in the owner's handbook. The figures are for cold tyres, so check them before a drive rather than after one.

TyresWhy do some rows give more than one pressure?

Many of these cars have two sets of figures: part load, for up to two people and a little luggage, and full load. Where Porsche gives both, the main figures here are the full-load ones and the note under the row gives part load, and the Comfort pressure where the car has one. Use the figure that matches how the car is loaded, and check again when that changes.

OilWhy does the oil depend on which model I have?

Because the engine does. Most generations were built with more than one engine, and each has its own oil grade, Porsche approval and capacity. Two cars from the same year that look alike can need different oil, so look for your exact model in the oil section, not just the generation.

OilIs the oil grade all I need to check?

No. The viscosity grade (for example 0W-40 or 5W-40) is only half of it. The oil also needs the Porsche approval listed for your engine (A40, C40 or C40 GT, for example), which is printed on the bottle. Two oils with the same grade can carry different approvals.

OilHow often should the oil be changed?

Follow the service schedule in your handbook or service booklet. Many owners change it more often when the car is used on track, or does lots of short journeys that never let the oil get fully up to temperature.

GeneralWhere do the figures on this 997 page come from?

From Porsche's own documents, named and linked under each figure. Where Porsche's documents disagree, or no Porsche figure could be found, the page says To be confirmed rather than guess. If a figure here ever disagrees with the label on your car or your handbook, the car and the handbook are right.

Choosing tyresSizes, the Porsche N mark and what to ask for

The 997 runs staggered tyres, and the rear size depends on the body. Rear-drive Carreras use 235/40 ZR18 front and 265/40 ZR18 rear, or 235/35 ZR19 front and 295/30 ZR19 rear. The wider four-wheel-drive cars use 295/35 ZR18 or 305/30 ZR19 at the rear, and the Turbo, Carrera GTS, GT3 and 997.1 GT3 RS use 235/35 ZR19 front and 305/30 ZR19 rear. The GT2 has 325/30 ZR19 rear tyres, and the GT2 RS and 997.2 GT3 RS use 245/35 ZR19 front and 325/30 ZR19 rear.

Porsche marks the tyres it has tested and approved with an N code, such as N0, N1 or N2, on the sidewall next to the tyre's name. Its approval lists for the 997 say to fit tyres of the same make, type, speed index and N code across the car, to replace tyres that are more than six years old, and that the recommended pressures apply only to approved tyres. Porsche notes that the GT3 range is fitted as standard with sports tyres developed for motor sport, which its lists class as ultra high performance tyres: road legal, but with a reduced tread depth and designed for circuit use as well.

Most 997 handbooks give two pressures: a part-load figure for up to two people without luggage and a higher full-load figure, which is the one shown in the table. The GT3, GT3 RS, GT2 and GT2 RS use a single, much lower figure, so never set a GT car to Carrera pressures or the other way round.
