Full-Synthetic 5W-40 for Automotive Engines

Valvoline SynPower 881050 is a full-synthetic engine oil formulated for cars and light trucks. The 5-gallon box supplies enough fluid for multiple drain intervals or fleet top-ups. It meets API and SAE standards for gasoline-engine protection.

SAE 5W-40 Viscosity Grade

The 5W-40 rating defines cold-start flow at minus 24 degrees Fahrenheit and high-temperature film strength at 390 degrees Fahrenheit. Kinematic viscosity measures 82 at 40 degrees Celsius and 13 at 100 degrees Celsius. A viscosity index of 168 confirms stable performance across that range.

Sustained High-Temperature Operation

Under continuous load the oil resists thinning thanks to its high viscosity index and 390-degree-Fahrenheit flash point. The pour point of minus 36 degrees Celsius ensures pumpability after cold soaks. Full-synthetic base stocks maintain protective film strength during extended drain cycles.

What standards does this Synpower oil meet and what do they cap in practice?

It meets API and SAE standards, guaranteeing the viscosity index of 168 and a flash point of 390 °F for automotive engines.

What space and fittings does the 5-gallon box need to sit and pour?

The box holds five gallons of amber full-synthetic oil; its pour-point of -36 °C ensures it flows from the container in freezing conditions.
