This is off of their Synpower FAQ's. The usual double talk answer...
Is Valvoline SynPower a full synthetic? Is SynPower motor oil PAO or ester based? Does it require a special filter?
Yes, SynPower is 100% synthetic. Synpower uses a proprietary combination of various types of synthetic base oils to obtain optimum performance.
No, a special oil filter is not required with Synpower.
I am not a proponent of Valvoline but if you just read what they say about the 5w40 you would be led to believe it is something really special.
SAE 5w40: Provides the widest range of protection available in the SynPower motor oil line. Delivers outstanding cold temperature pumpability for rapid oil circulation at start-up. Provides a thick oil film for ultimate wear protection. Exceeds all car and light truck manufacturer’s warranty requirements for the protection of gasoline, diesel and turbocharged engines where an API SJ or CF oil is recommended. Exceeds European ACEA A3/B3 and all preceeding API Gasoline Engine Oils. Meets or exceeds the engine performance requirements for BMW, Bentley, Corvette (GM4718M), Jaguar, Lexus, Mercedes-Benz, Porsche, Rolls Royce, Volkswagen, Volvo and other high performance vehicles.
