Valvoline High Mileage 150K with Maxlife Plus Technology Motor Oil SAE 5W-30 1 QT, Case of 6

What It Is

Valvoline High Mileage 150K with Maxlife Plus Technology is a synthetic blend motor oil formulated specifically for gasoline engines with over 150,000 miles. It’s designed for walk-behind mowers, riding mowers, and small engines that require SAE 5W-30 viscosity and have accumulated significant wear.

Fitment & Compatibility

Before buying, check your mower’s owner’s manual for the recommended oil viscosity and API service classification (typically SJ through SN). This oil is SAE 5W-30, so it’s compatible with most air-cooled small engines from Briggs & Stratton, Kohler, Honda, Kawasaki, and Tecumseh that specify 5W-30. It is not for 2-stroke engines or diesel mowers. For riding mowers, verify your engine’s oil capacity (usually 1–2 quarts). This case of 6 quarts covers multiple oil changes or a single large-engine mower.

Key Things to Know

• Quality: Synthetic blend with added detergents and seal conditioners to reduce leaks and oil consumption in high-mileage engines. Meets API SN Plus and ILSAC GF-5 standards.
• Installation difficulty: Easy – just drain old oil, replace filter (if applicable), and refill. No special tools beyond a wrench and oil pan.
• Common gotchas: Do not use in engines specifying SAE 30 or 10W-30 without verifying compatibility. Overfilling can cause seal damage; always check the dipstick after adding.
• Shelf life: Unopened bottles last 5+ years if stored in a cool, dry place. Once opened, use within 2 years.

Should You Buy It

This is ideal for owners of high-mileage walk-behind or riding mowers (150k+ miles or equivalent engine hours) who want to reduce oil consumption, prevent leaks, and extend engine life. If your mower is newer or low-mileage, a standard SAE 5W-30 or 10W-30 will suffice.
