Valvoline High Mileage with MaxLife Technology SAE 5W-20 Synthetic Blend Motor Oil 5 QT

Engines with high mileage on the odometer face conditions that fresher motors do not: hardened seals that begin to weep, gradual wear at contact points, and the buildup of sludge and deposits inside the block. Valvoline High Mileage with MaxLife Technology SAE 5W-20 is a synthetic blend built around that stage of an engine's service life. The formula carries seal conditioners intended to restore flexibility to aging seals, detergents that work against deposit, rust and corrosion accumulation, and friction modifiers aimed at wear protection. It meets the ILSAC GF-6A, API SP, API SN with SN PLUS and API SN specifications, and is formulated and made in America.

One note on fit: this is a 5 quart container of 5W-20 only. Confirm your owner's manual calls for that grade, since it will not substitute for engines specified at a different viscosity.

When switching to this oil on a high-mileage vehicle, plan the first change interval a little shorter than usual, around 3,000 to 3,500 miles, so fresh oil can begin working on accumulated deposits without carrying them too long. After that initial service, you can follow the interval your owner's manual recommends for conventional or synthetic blend oil. Store unused portions of the container in a cool, dry location away from direct sunlight, with the cap tightly sealed to prevent moisture contamination and viscosity drift over time.

A five-quart container is the right size for most four- and six-cylinder passenger cars and light trucks that take a standard oil change, typically between four and five quarts depending on whether you account for filter capacity. It leaves little to no waste for those vehicles, which makes it a practical purchase compared to buying a larger jug and storing the remainder. When comparing high-mileage oils in this category, pay attention to whether the product is a full synthetic or a synthetic blend, since blends tend to sit at a lower price point while still offering meaningful additive packages for aging engines. This product suits drivers who have crossed the 75,000-mile mark and want targeted protection without committing to a full-synthetic price.
