Valvoline has a long history of making oils.
When I joined the site back in 2000, the only synthetic on the shelf worth buying was Mobil 1. As the demand for synthetics increased, so has the competition from SOPUS and Ashland. Synpower has become a more competitive product over the years.
Valvoline has a state of the art lab in Kentucky and is capable of running all the API Sequence Engine testing for API approval. Their oils are all very good, and even their specialty oils like MaxLife are a great vaule.
Are they better than the competition? No, not necessariliy. Most of these products perform about the same, with each having a slight advantage in specific areas.

While Valvoline’s formulations are a trade secret Valvoline has at its disposal, Group III, Group III+, Group IV (PAO) and various Group V base oils and we use these as appropriate to meet our high standards. Valvoline is free to choose whatever base oils and additives we desire to meet our performance goals. Many of our competitors, due to corporate affiliations may not have this freedom.
