Is there a synopsis for folks that don't want to spend 20 minutes watching this please?
A very good question. I knew this video would not be for everyone. It's got some strange glitches which I think may be due to AI help. And if you do not already have some background with the subject, it can be difficult to keep up with the video, which assumes more knowledge than the average person can be expected to have.
It's also somewhat vague when it could have been more clear. But let me see if I can give some bullet points that get us to the crux of the matter.
1. Everyone starts with a base oil and combines it with an additive package.
2. The base oil and the additive package make a big difference, both in performance and price.
3. The 2 major players in this discussion are Group III (Highly Refined Mineral Oil), and Group IV (PAO - A Chemically Engineered Oil)
4. Group III needs a very good additive package to hold up well in modern engines. Especially if the engine oil also lubricates the transmission.
5. Group IV uses a process that builds, or engineers, the desired molicules to exacting specifications. As such, it usually needs little to no additive package. Because the process builds in the desired charastics.
6. Group IV is known for being of extreme purity with a high VI, Viscosity Index (Able to resist shearing and viscosity drop). It also possesses superior thermal stability (Able to resist heat degredation), and cold start, low-temperature flow.
Mobil1, along with Amsoil and a few others, were making true synthetic oil when Castrol began to label their mineral base oil as 'Full Synthetic'. Mobil1 sued them for false advertising, which it was. But they lost. This allowed Castrol, and others, to market their inferior (Note that I said 'Inferior', not inadequate), product which could now compete with the superior true synthetic lubricants at a lower price point.
True synthetically engineered molicule lubricants have a number of advantages over any Group III product. This video tries to make a few very pertinent points.
1. The customer deserves to know what they are getting.
2. Many times, the customer is paying more for a product that does less due to the false marketing allowed by the court decision.
3. Marketing should inform, not deceive.
Why the US court sided with Castrol (we are the only nation in the world that allows a mineral based oil to be classified and marketed as 'Synthetic'). Many experts in the industry consider this a miscarage of justice. The marketing people consider it a windfall for profits.
This is not to say that Group III oils are bad. The video rightly is careful to say that most are 'Adequate' if you change oil at 5,000 miles. Which is exactly where the XPS oil begins to shear and lose viscosity pretty drastically. But the service interval for our Spyders is 9,300 miles. And I think this is a significant combination of detail.
