I found it very informative, debunking many myths and mysteries along the way.

What is does not explicitly say is that basically you get what you pay for and what you pay for is a combination of base oil and additive package
Buy a Redline group 5 polyol ester oil at twice the price of a group 4 Mobil One polyalpha olefin or 3 times a Valvoline group three "synthetic" . The additive package is one thing but the base oil is another and you cant make a good oil with just an additive package you also need a good base oil.
How much you need to spend depends on the engine you have and how you use it.
The minimum I would use is a group 3 like Valvoline "synthetic" for a moderately loaded road car engine like my Landcruiser. For a full race engine being used at 8000 rpm plus in my elan I would use a group 5 Redline.
