Like him or not Lake Speed Jr. knows lubrication. He helped Gibbs "Driven" brand become the gold standard for many race teams.
Viscosity breakdown is something I know about first hand. With 53 years of trucking under my belt I experienced oils going bad just by keeping track of oil consumption.
For decades the 10,000 mile oil change was the normal in class 8 trucks. And I routinely saw oil consumption go up in the latter stages of that oil change interval. @ 8000 miles I was adding a gallon of oil more frequently.
Some guys would run the engine one gallon low on purpose to cut down on oil usage....but it also increased wear.
I did routine oil sampling for almost 25 years in my equipment. I could see the oil viscosity drop as the miles increased. Oil usage increased... oil pressures dropped.
By the 2000's oils improved. The 15,000 mile service interval became the norm.
I rocked the boat and went to 50,000 miles!
By understanding the oil sample reports I saw which oil lasted longer...the viscosity index stated healthy for a longer period of time.
I saw great numbers by adding Lucas Oil Treatment to the oil. It's nearly a pure VII... viscosity index improver.
The last Pete I owned went 1,918,000 miles before its first rebuild. I bought it @ 900,000 miles and started those 50k service intervals almost immediately.
The engine went down after a cylinder liner perforated caused by the cheap coolant I was using.
The rings and bearings could have gone another 500K if not for the water intrusion into the oil caused by the hole in the cylinder liner.
My son, who has owned big trucks for 30 yr years, would cringe when I mentioned my long oil change intervals.
My point here is watch this video. Look past his presentation to listen to the facts.
You will here a slight prejudice against one particular oil brand...one that I share going back 40 years. Think "castor" oil...
HIs main point here is timing chains and gears kill oil viscosity. And that kills engines. Think about that the next time you buy a modern car with a 10' long timing chain and try to go 7500 miles between oil changes. Or something with cam phasers.
And his opinion on the oil additive packages is insightful. Looks like the Luberizol folks have the answer ..Shell/Mobil do not.
