Tangent,

With all respect, I think that you must be off on a tangent. If you are talking about the original beetle, they were air cooled POS engines. In Germany or in other cooler climates these engines would hold up okay, maybe. In the heat, they wouldn't hold up at all.

200,000 miles on an air cooled 40HP or 52HP air cooled beetle would be about as impossible as anything mechanical could be. If you DID manage to get that mileage from one, it would be with MANY valve adjustments and more than one jug job.

I drove a '68 Beetle 52,000 miles or so in Germany in about 23 months in 1969 to 1971. This was before we had the better oils that we have now days. If you were to try your 200,000 mile test now with modern oil, specifically Mobil One, and if the stars were to perfectly align and you drove it carefully, etc........... You MIGHT be successful, but I would like to place a bet on such a test.

Have a great day,
