TECHNICAL LIBRARY Correctly setting your oil level (1997-08 Boxster, Cayman, 911) · The purpose

TECHNICAL LIBRARY Correctly setting your oil level (1997-08 Boxster, Cayman, 911) The purpose of this directive is to address concerns with excessive oil consumption due to overfilling. NOTE: Per Porsche ATI SC1 0604, the maximum value for engine oil consumption is up to 1.5 liters in 1000 kilometers or 1.6 quarts in 622 miles. Normal oil consumption for an engine with low tension rings and nikasil plated bores is 1 quart in 1000 miles. Oil level on this generation of engine is done via dipstick on early models (preferred method) or with electronic oil level sensor. Later vehicles are not fitted with dipsticks, so you may be limited to using the electronic oil level indicator with level indicated on the dash instrument cluster. Oil level should be checked and corrected only when the vehicle has not been operated for a minimum of 8 hours with engine cold and parked on a level surface. Do not start up the engine prior Old style dipstick, Porsche part # 99610701454 to checking oil. Countdown after engine shutdown is insufficient to allow time for oil to drain back to the sump completely. Waiting for the countdown to zero to read the oil level is not sufficient time to allow all the oil to drain back to the sump. It is recommended to run the oil level ½ a quart low, however Porsche put out revised programming and dipsticks beginning in the 2002 model year which effectively reduced total system volume by this amount. Starting at engine number # 662 11795 for the 2002 model year*, Porsche already adjusted the oil level sender and dipstick on Porsche 911 models to read ½ a quart lower to reduce smoking at high engine speed under cornering. Vehicles fitted with updated dipstick part number 996-107-014-55 should have the oil level set to the full mark. This applies to vehicles beginning with production on January 8th, 2002 as of the following VINs: 99 52S 62 1921 – Coupe 99 02S 63 5312 – Targa 99 X2S 64 2784 – Cabriolet 996 models fitted with the 996-107-014-54 dipstick should have their oil levels set to half way between the min and max marks on the dipstick.
