Questions

TyresWhy does my 992 show more than one pressure for the same tyres?

For most 992s Porsche gives a part-load and a full-load pressure, and on many cars a lower Comfort pressure for speeds up to 270 km/h. Set the tyre type, size and load condition in the tyre pressure monitor and choose Standard or Comfort to match what you have inflated the tyres to, so the warnings are correct. The GT3 and GT3 RS have one standard pressure plus a lower Performance pressure.

OilCan I use 5W-40 in my 992?

Only in a 2020 model-year car, where the handbook allows 5W-40 above minus 25 C. Porsche's oil list says only 0W oils may be used from model year 2021, so use a 0W-40 with Porsche C40, or C40 GT for the GT3, GT3 RS and S/T.

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 992 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 992 also runs wider tyres at the rear. Carrera models use 235/40 ZR19 front and 295/35 ZR20 rear, or 245/35 ZR20 and 305/30 ZR21 on 20/21-inch wheels, which are the only summer sizes approved for the S, GTS and T; the 992.2 GTS takes a 315/30 ZR21 rear. The Turbo, Turbo S, Sport Classic, GT3 and S/T use 255/35 ZR20 and 315/30 ZR21 (325/30 ZR21 rear on the 992.2 Turbo S), the GT3 RS uses 275/35 ZR20 and 335/30 ZR21, and the Dakar uses 245/45 ZR19 and 295/40 ZR20, with an approved all-terrain tyre in the same sizes.

Porsche marks its approved tyres with a code on the sidewall beside the tyre's name. On most 992 road models it reads NA0, NA1, NA2 and so on, while GT3 tyres use codes such as N0 or N1. Fit the same make, type, speed rating and code across the car, and treat the handbook's load and speed ratings as minimums. Some sizes are approved in two load ratings, so match the markings on the tyres you are replacing.

After fitting new tyres, enter the tyre type, size and load in the tyre pressure monitor so its warnings are correct. Porsche recommends replacing tyres more than six years old and does not recommend repairs. Winter tyres have their own sizes and pressures, and the GT3 and GT3 RS have a lower Performance pressure, valid up to 290 km/h, which should be used only when it is selected in the instrument cluster.
