My understanding is that bore scoring is more of a metallurgy issue. The cylinder liners were coated with an Alusil or Nikasil insufficiently tough material that breaks down under extreme stress, such as very cold starts where there’s no lubrication in the cylinder bore. It’s why the Mezger based engines of the same era didn’t have issues, as they retain a Nikasil cylinder bore coating just like the air cooled cars. It seems the issue has been traced to cars in cold climates, which would suggest that how you operate the car is probably not a big factor.
