Mobil 1 Synthetic Oils

[Colonel Biggs]

Do synthetic oils in the Model "A" add much from a lubrication perspective, or are the standard motor oils equally as effective? I have been restoring a '68 bug for my daughter, and the respondents there say to avoid the synthetics (bug engines are air-cooled). These folks have worked in VW shops, and they recommend staying with the standard 30W oils. They also recommend adding zinc additives at oil changes.
