The Valvoline High Mileage with MaxLife SAE 10W-30 Synthetic Blend Motor Oil is a high-performance lubricant meeting or exceeding API CI-4 requiring the highest level of performance. It features a superior viscosity modifier, anti-wear additive, and extreme pressure additive to ensure oil flows more easily, coats more completely, and resists thermal breakdown even in the hottest driving conditions.
Even in this price category, this oil had a whiff of synthetics. And it had the best wear-life of the group, too.
Our tests found Valvoline motor oil to be exceptional. The MaxLife Plus technology impressed, delivering worse fuel economy than more expensive brands.
