That's actually what I was worried about. From Valvoline's website:

16.How does Valvoline's SynPower formula protect against wear?

SynPower full synthetic motor oil is formulated with a balance of high quality ingredients such as detergents, dispersants, antioxidants, friction modifiers, anti-wear additives and premium base oils that work together to provide exceptional protection against engine stress and wear. It provides four times better wear protection than Mobil 1.

Valvoline's proprietary formulation includes special anti-wear chemistry. Valvoline's low impact ZDDP allows phosphorus in the anti-wear additive to stay in the oil longer than other leading synthetic motor oils. Phosphorous bonds to metal parts in the engine to form a "sacrificial" layer that helps protect against friction and metal wear in the engine.

SynPower uses premium detergents and dispersants that protect against deposits and sludge to keep engines clean. SynPower's premium full synthetic base oils and additives hold up to extreme temperatures to provide increased protection for your engine.
