Valvoline High Mileage with MaxLife Technology 5W-30 Synthetic Blend Motor Oil 1 Quart

What It Is

Valvoline High Mileage with MaxLife Technology 5W-30 is a synthetic blend motor oil designed for engines with over 75,000 miles. It’s formulated for four-stroke lawn mower engines—commonly found in walk-behind mowers, riding mowers, zero-turns, and garden tractors—to reduce leaks, oil burn-off, and wear in older engines.

Fitment & Compatibility

• Engine type: Only for four-stroke (gas) engines; do not use in two-stroke or diesel mowers.
• Viscosity: 5W-30 is ideal for small engines operating in temperatures from 0°F to 100°F. Check your mower’s manual for recommended oil weight—some older or heavy-use mowers may require SAE 30 or 10W-30.
• Capacity: Most push mowers need 15–20 oz (one quart covers one oil change). Riding mowers may need 1.5–2 quarts—buy extra if needed.
• OEM vs aftermarket: This is a high-quality aftermarket oil, fine for all major brands (Briggs & Stratton, Kohler, Kawasaki, Honda, Toro, John Deere, Craftsman). No special OEM oil required.
• Measurement: Check your dipstick or manual for exact oil capacity. Do not overfill—fill to the full mark on the dipstick.

Key Things to Know

• Installation difficulty: Easy—drain old oil (warm engine), replace drain plug, refill. No special tools needed.
• Quality: Synthetic blend with seal conditioners to reduce leaks in high-mileage engines. Exceeds API SN and ILSAC GF-5 standards.
• Common gotcha: Not for engines under 75,000 miles—it’s thicker and may cause foaming or drag in newer, tight engines. Also avoid in extreme cold (below 0°F) or hot (above 100°F) climates.
• Storage: Sealed bottle lasts 5+ years if kept in a cool, dry place. Dispose of used oil responsibly at auto parts stores or recycling centers.

Should You Buy It

If your mower has 75,000+ miles (or is a decade old), this oil is a smart buy—it’s affordable, widely compatible, and proven to reduce leaks and smoke. For newer or low-mileage mowers, stick with standard 5W-30 or SAE 30.
