Oil Change Frequency after LN IMS Bearing

[mnc-i]

Perfetlap,

Thanks for the info.

I promised myself that I would purchase a 996 series (1999 - 2004) 911 once I clock 300,000 miles.

Can you tell me which model year 996s, if any, came with dual row bearings?

Any assistance you can provide is greatly appreciated.

P.S. "I just purchased 10 quarts of Royal Purple 20W50. The label states zinc/phosphorous fortified."

The 996's mirror the Boxsters; 1997-2001 (partial) run dual rows, 2001 (partial) - 2005 (partial) run single rows, and 2005 (partial) - 2008 run the oversized third design IMS bearings. The model years noted as "partial" are transition years and the cars could have had either design, and the only way to know which is in the car is to take it apart and look.
