I was reading an article about oil in Old Cars Magazine a month or so ago. There was the usual discussion about new oils being bad for old flat tappet engines unless it carries the SL rating but it also noted that the term "Synthetic" is just a marketing tool any more. I don't remember the exact terminology and I don't have the article to refer to anymore but I believe it said all (maybe most) current "Synthetic" oils are specially treated dino oil. They are a higher quality oil but there's nothing synthetic about them. I thought that was a freeking rip-off, no better than calling a piece of glass a diamond so you can charge more.
