It seems the major advantage of Premium Plus Passenger Car Engine Oil is for cold weather.So our PCMO oil has AN, Ester and Moly just like the premium plus. The premium plus is PAO with a Star VII. Both of those are most beneficial when you are in a colder climate. If you are in North Carolina you would honestly be throwing money away by using the premium plus series over the PCMO. And as always the BITOG15 discount code is important to remember for 15% off.
