Where does it state the "total base number"?
It's like they don't want you to know that it's fake synthetic hydrocracked group III oil lol
Group categories are not "ratings," they are categories based on the API 1509 classification system. For example, Group I means "conventional, solvent refined" base oil (not considered synthetic); Group II means "hydroprocessed/hydrocracked" base oil (not considered synthetic); Group III means "all hydroprocessing/hydrocracking + isomerization" base oil (which is considered synthetic); Group III can also mean "Gas to Liquids (GtL), which is what the Pennzoil Platinum motor oils with PurePlus Technology are made from (immensely simplified, GtL means: "from Natural Gas/Methane to hydrocracker to base oil")(which is also considered synthetic); Group IV means Poly Alpha Olefin/PAO" base oil (considered synthetic). Group V means "everything else"
The Pennzoil Platinum and Pennzoil Ultra Platinum motor oils with PurePlus Technology are both made using the Group III Gas to Liquids base oil, which is a truly "synthesized from natural gas" synthetic base oil. But please remember, today's PCMO engine oils contain somewhere between 18-23% additives so, you can have the greatest base oil, but if you couple it with a mediocre additive package, you will have a mediocre finished product! This is where our "PurePlus" name derives from: Gas to Liquids "Pure" base oil + the most advanced "Plus" additive package
