Cyls still have hone marks and it did not use any noticible amount of oil.

In 74 he bought another Super Beetle new and drove it 145K on Penz 10w-40 just like the 70. He wrecked it in 82 and it was running fine. Neither had more than regular maintenance and both went up Cajon Pass daily in 100+ temps.


71 was the first year for the Super.

He probably bought a 1971 model year in late 1970.

From my experience, oil bath filters are best suited on low CFM applications that can't pull the air/dirt in so fast that it never gets to the oil.

One downside to a oil bath is the fact you got to keep the deal level more/less...something that gets tilted quite a bit can actually have the oil slosh to one side allowing dirty air to pass, or worse yet, allow the oil to suck into the intake.
