AFAIK, there are only 4 true synthetics on the market:
Amsoil, Redline, Rpyal Purple, and another I can never remember the name of.

Not true at all. It's a trick of marketing types and lawyers that make you think M1 is
synthetic.
A true synthetic starts with a PAO base stock, no dino
oil. Then it's further refined, and the package is added. The key is there is no dino
oil.
Oils like M1, QS, etc start with standard dino oil. Then they refine and add until it meets the legal requirements as established by the courts to be allowed to use the term "synthetic". It's a marketing trick, don't fall for it.
However, that's not to say they are bad oils. They're not. They do perform better than standard dino oils. But not as good as a true synthetic. Most people don't need the performance of Redline or RP. If you can get M1 pretty cheap, there's no reason not to use it. This is not a case where you get what you pay for.
As for reduced friction, that's true. Semi-synth's are better than dino, but not as good as true synth. If you're racing and need every last hp, it's worth the expense for a true synth. If it's a street car that gets less than 5K miles a year, you'll get the same performance using standard Penzoil (or maybe wallyworld) and changing it once a year.
