Valvoline High Mileage 150K with Maxlife Plus Technology 10W-30 Motor Oil 1 Quart

What It Is

This is Valvoline’s High Mileage 10W-30 motor oil formulated for engines with over 150,000 miles, using MaxLife Plus Technology to reduce leaks, sludge, and wear. It’s designed for 4-stroke lawn mower engines (push, riding, zero-turn) that specify 10W-30 viscosity.

Fitment & Compatibility

Before buying, check your mower’s engine manual or dipstick for the recommended oil viscosity (SAE 10W-30) and capacity (typically 18–20 oz for small engines). This oil is not for 2-stroke engines or those requiring SAE 30, 5W-30, or synthetic blends. Compatible with most Briggs & Stratton, Kohler, Honda, and Kawasaki engines that call for 10W-30—common in many residential mowers with 140cc to 500cc displacement. No OEM-specific restrictions; it’s a universal aftermarket oil.

Key Things to Know

• Quality: API SN/SP certified, meets modern small-engine standards; high-mileage additives help condition seals and reduce oil consumption in older engines.
• Installation difficulty: Easy—drain old oil, replace filter if equipped, refill to dipstick mark. No special tools needed.
• Gotchas: 1 quart is enough for most mowers (check capacity—some take 20 oz, others 24 oz). Do not mix with other viscosities or non-high-mileage oils. Overfilling can cause smoking or seal damage.
• Storage: Unopened shelf life ~5 years; keep sealed and away from extreme temps.

Should You Buy It

Buy this if your mower’s engine has over 150,000 miles (or is high-hour, aged, or burning oil) and calls for 10W-30. It’s ideal for extending the life of a well-used machine without switching to a full synthetic. Skip it if your engine is newer or requires SAE 30 or a different viscosity.
