Although the
Engine Oil article is written for the classic car owner, I don't believe that I have written the article as specific advice for antique and classic cars only. If you re-read my Oil Recommendation section, I do recommend extending OCIs to coincide with tire rotations.
As for the low temperature advantages of synthetics, thank you for bringing this to my attention. Although I have mentioned it indirectly, I will have to add more information in this regard. It is the first draft after all and there is plenty of room for improvement.

Based on what I've read from Widman and Haas, many people seem to
underinflate the importance of getting an oil to operating temp viscosity. Do you disagree with Widman's
Corvair Oil article or Haas'
Motor Oil Basics article?
