Well, I watched, I heard all that. It seems almost bizarre an oil engineer could be so annoyingly antediluvian, obtuse, wishy-washy! And, I strongly, emphatically disagree ! And Ironically, unquestionably so does/ did the Saab engineers! They clearly, strongly recommend(ed ) Synthetic oil ! There are real, demonstrable, absolutely undeniable advantages of synthetic oil ! Of course, the Saab engineers, they were up against a real conundrum - The cause of sludged motors! let us not forget they were giving owners brand new motors to replace sludged ones ! ( And they were not the only car company that had a sludge issue BTW ! ) It is NO accident that the incidence of sludged engines markedly decreased when synthetic oil became deriguer! (common ) Albeit the mystery of sludged engines is worthy of an unsolved mystery episode! Many causes were posited and yet no one single, definitive eliciting cause found. I rather think it was a combination of causes! Re the question of whether to use Synthetic oil? We have wise counsel I heed. As per the scientists, engineers of Consumers Reports :
TECH TALK
When should you consider synthetic oil?
Although more costly, synthetic has its advantages
Published: July 08, 2015 08:00 AM
"Many automakers require owners to use synthetic motor oil in their cars’ engines. This is because synthetic oil has some advantages over conventional motor oil. It’s designed to be more effective at:
Resisting break-down, and thus lasts longer than mineral oil
Withstanding high temperatures
Flowing in cold temperatures, thus reducing engine wear during frigid startups.
However, synthetic motor oil can cost two to four times as much as regular oil. So unless your owner's manual specifies synthetic, you don’t need it. But Consumer Reports’ chief mechanic says there are some situations where synthetic oil’s resistance to breakdown can help prolong the life of an engine.
If you make lots of short trips, standard motor oil may never get warm enough to burn off moisture and impurities. That could hasten the breakdown of conventional oil. Also, if you live in a region with very cold winters or very hot summers, or if you use your vehicle for towing or hauling heavy material, synthetic oil won’t break down as quickly. While synthetic generally holds up better and can serve for more miles, it is important to not extend oil changes beyond the time interval recommended by the manufacturer—typically six months or a year.
Another good use for synthetic oil is as a salve for older engines prone to sludge buildup. This gunky residue can block oil passages and lead to a quick death of an engine. In the early 2000s, several engines from Chrysler, Toyota, and Volkswagen, SAAB ! among others, were especially prone to sludge buildup. This sludge forms when oil breaks down. Synthetic oil would be beneficial in those engines, as it is less likely to form troublesome sludge.
Using synthetic in these situations will prolong your oil life and require fewer changes. That’s a major benefit to the environment, as used motor oil is a major source of toxic waste in water. Your pocketbook will also thank you " ........................................ PS I use Blackstone labs for oil analysis! I fitted a much larger than stock oil filter ( about 1 liter larger ! ) and wrapped my exhaust pipe w/ insulating lava wrap tape especially as it IS close to the oil pan as he said! .................. As is said " Those who do not study history are doomed to repeat the misstakes of the past " er actually, 'Those who cannot remember the past are condemned to repeat it.' (George Santayana-1905). In a 1948 speech to the House of Commons, Winston Churchill changed the quote slightly when he said (paraphrased), 'Those who fail to learn from history are condemned to repeat it.'LOL
