Hahaha fair enough lol. Probably best to keep the rocket science to the rocket scientists[emoji23]

molybdenum is a big one for friction reduction aka wear reduction but again is a fine line to much and you will lose ring seal
and get cylinder glazing / Hazing which is really bad I mention this to give you a idea of how each one plays a part and how to much of one can cause a imbalance or issue with the motors normal function.
This is again why i try to find a oil that tests with the standards of CJ4 and CK4 not just CK4 and call it good most oils that are CK4 mention backwards compatability with CJ4 but do not actually do some of the tests that were done in the CJ4 standard so its very confusing and oil chemistry is a very complicated thing so again I look for a oil with both testing standards and then look for additive package with good soot dispersement and well a respectable group IV PAO oil content as this oil lasts much longer than the group III's before breaking down and is the true synthetic unlike group III which is just highly refined dino oil not even really synthetic at all which is delo and rotella synthetic so you know straight group III no or little to none of group IV POA.

HIGHLIGHTS
Group III — Wax isomerized or hydrocracked crude oil refining process. Group III base stocks are considered synthetic because their molecular structures are altered through an intended chemical reaction. Very low wax and aromatic content. Used in the
majority of synthetic motor oils.
Group IV — Polyalphaolefin (PAO) base stocks are chemically synthesized from ethylene. Used in
some synthetic motor oils.
Unfortunately, manufacturers and marketers of synthetic motor oils can be less than forthcoming with information regarding the types of base stocks and additives used in their product formulas. As a result, the only way to determine their quality and effectiveness is through a series of American Society of Testing Materials (ASTM) tests. For example, the Noack volatility test (ASTM D5800) measures the evaporation loss at high temperature. Another favorite is the High Temperature/High Shear (HTHS) test (ASTM D5481), which measures the viscosity of motor oil under high temperature and shear conditions.
Though they have similar performance characteristics, should you be concerned about the substitution of Group IV or V with Group III base stocks in your synthetic motor oils? Your application, maintenance schedule, and the targeted price point will determine the answer.
Full synthetic motor oils manufactured by the major brands and sold by the leading automotive chain stores are comprised of primarily Group III base stocks. Although some may also contain small amounts of Group II base stocks, they are good-quality motor oils with American Petroleum Institute (API) approvals that you can confidently put in your crankcase knowing they meet the requirements of new-car manufacturers.
However, by no means are Group III synthetic motor oils of the highest quality or necessarily the best product for your application. Pricing and affordability will be determining factors, as well as driving environment and intended use of your vehicle. A Group III-based full synthetic motor oil on sale at the local mega-store may be the best value if your requirements are ordinary, such as city or highway driving, the occasional autocross, and back road driving. But if vehicle use and ambient conditions will be more demanding, including high-performance driving, high heat or extreme cold, frequent short trips, longer oil change intervals, etc., a motor oil with Group IV or V base stocks may be for you.
Generally, Group IV and V base stocks, such as polyalphaolefins, esters, or polyalkylene glycols, will have performance advantages over Group III base stocks regardless of how well refined they may be. These advantages include a lower pour point (temperature at which the oil becomes semi-solid), less volatility or lubricant evaporation due to temperature, and better shear protection (more resistant to physical breakdown). Most formulators of high-performance synthetic oil will blend a variety of Group IV and V base stocks, which can help build a type of synergy between them. They also are often blended with Group III base stocks to help control the price and aid with the solubility issues sometimes associated with certain types of Group IV and V base stocks.
