Most air cooled early 911's took 10 with filter. '72 was unique with 8 1/2 because the dry sump oil tank was placed ahead of the rear wheel for better weight distribution. They had to go back to the tank behind the rear wheel in '73 because of new USA side crash regulations. I loved that car, but as it became more valuable and sought after as a collectable I became more and more paranoid about it, which ruined the driving pleasure.nice car

It was time for this old man to move on...
But yes..with a high oil capacity combined with a dry sump oiling system, the air cooled 911 models were as much oil cooled as air cooled.
