I agree, if it was wrote before 2007, it no longer applies. Oils are different, engines are different, and emission regulations are for sure different.

Oil is not 'different'. Its still dino oil with an additives package. The only 'difference' is now that zinc and phosphorus are being REPLACED with other additives that do not harm catalytic converters and o2 sensors, as well as reduce emissions.
Flat tappet motors are still very common (they are called 'inverted bucket' by Ford and modern API oils still meet wear and scuff criteria.
