“I use this oil on my 987.1 3.4 Cayman S. Previously, I used it on my 996.1 3.4 911
This is the 'go to' oil as recommended by Hartech for any of this era Porsche.”
“Ideal for 911 996, better o p at idle, quieter engine overall. Especially Careful with warm up in really cold weather. 10w 50 original oil weight for this engine.”
