Most engine oils are now formulated with Group II (hydrotreated) or a mixture of Group I (conventional mineral oil) and Group II base oils to meet the latest API gasoline and diesel performance designations.

Because Group III and Group IV (PAO) base oils are both considered synthetics (since 1999), any oil labeled as a full synthetic would contain either Group III or PAO, or both. Any oil that is labeled as a partial synthetic, semi-synthetic or synthetic blend would contain Group I or Group II (mineral oil) plus some amount of Group III oil or PAO (synthetic). Keep in mind that there is no minimum quantity of synthetic base oil required in order to call a blend a semi-synthetic lubricant.

There are also no designations for end users to know what specific base oils the oil formulator has used, so your question is a bit academic in nature. We would never be able to tell if we were purchasing a Group III engine oil vs. a Group IV (PAO) engine oil.

However, from an academic point of view, I would expect the cleaning ability of a Group III and a PAO to be similar (generally poor). Again, academically, I would expect less risk of seal issues, etc., when switching from a Group III oil (as opposed to a Group I oil) to a PAO, as the Group III oil and PAO are chemically similar.

Ester synthetics have a higher degree of solvency than Group II, III or PAO base oils. This means they will dissolve additives and deposits more readily and may cause some seals to swell slightly. They also can remove some paints. These characteristics (other than paint removal) can be beneficial, so some oil formulators will add small amounts of ester base oils into their synthetic (Group III and PAO) formulations to improve these properties.

 

MANUFACTURING PROCESS OF ENGINE OIL is not very complicated. For the production, there is need usable and tried a formulation, ingredients ( performance and another additives, base oils,foam agent, pour point depressant, etc. ) and process tank. For ingredients to be used, quantities to be used and ingredients usage rankings, you should look into this formulation and manufacturing process. Therefore, formulation and productıon process of MULTIGRADE, MONOGRADE,SYNTHETIC,SEMI SYNTHETIC MOTOR OIL are important. If you have not a good formulation, you cannot make healthy and  efficient production of any lubricating oils.
