20 percent better wear protection
50 percent higher oxidation resistance
80 percent better high-temperature viscosity control
But that’s not all. Volvo VDS-4.5 also offers significantly longer drain intervals than other API CK-4 heavy-duty engine oils – up to 60,000 miles depending on engine, application and idle time.
