Valvoline Extended Protection is a fully synthetic motor oil sold here as a four-pack of 5-quart jugs in 5W-20. It is Valvoline's step-up full synthetic, positioned above its basic full synthetic line and aimed at longer drain intervals and better wear protection. The 5W-20 grade suits many modern four-cylinder and V6 engines that specify a thin oil. Buying four jugs covers several oil changes, which makes sense for owners who service their own cars.

Owners of full-size trucks and cars who use Valvoline Extended Protection generally report smooth running and clean engines at high mileage. Some question whether it is worth more than Valvoline's basic full synthetic.
