Valvoline Full Synthetic High Mileage with MaxLife Technology SAE 5W-30 Motor Oil 1 QT (Pack of 2)

What It Is

Valvoline Full Synthetic High Mileage with MaxLife Technology SAE 5W-30 Motor Oil is a premium engine oil designed specifically for older or high-mileage small engines (typically over 75,000 miles of equivalent use) in lawn mowers, tractors, and zero-turn mowers. It helps reduce oil burn, leaks, and deposits in engines that have accumulated wear.

Fitment & Compatibility

• Engine types: Fits most 4-stroke (overhead valve, side valve, and OHV) lawn mower engines from Briggs & Stratton, Kohler, Kawasaki, Honda, and Tecumseh. Not for 2-stroke or diesel engines.
• Viscosity: SAE 5W-30 is the most common winter-grade oil for mowers used in cooler climates (below 40°F). For warmer regions (above 80°F), SAE 10W-30 or 30-weight is often recommended. Check your owner’s manual for the correct viscosity.
• Capacity: 1 quart (32 oz) per bottle. Most push mowers take 15–20 oz; riding mowers typically take 48–64 oz (2–3 quarts). You’ll likely need 2–3 packs for a full change on a rider.
• OEM vs aftermarket: This is a universal aftermarket oil, not OEM-specific. It meets or exceeds API SN, SM, SL, and SJ standards, making it safe for any 4-stroke engine that calls for 5W-30.

Key Things to Know

• High-mileage formula: Contains seal conditioners and detergents that reduce leaks and sludge in older engines. It’s not necessary for new or low-hour engines—standard synthetic is fine.
• Installation difficulty: Easy. Drain old oil (warm engine, tip mower or remove drain plug), replace filter if equipped, refill to the dipstick full mark. No special tools needed.
• Common gotcha: 5W-30 is thinner than 10W-30 or SAE 30. Using it in a hot-running mower (e.g., zero-turn in summer) can lead to oil thinning and insufficient protection. Stick to the manual’s recommended viscosity for your climate.
• Pack size: 2 quarts per pack. If your mower takes 20 oz, you’ll use about 1.25 quarts per change—buy 2 packs (4 quarts) to have extra for top-offs between changes.

Should You Buy It

Buy this if you have a high-hour (75,000+ equivalent miles) 4-stroke lawn mower engine that specifies 5W-30 and you want to reduce oil consumption, leaks, or deposit buildup. Skip it if your mower is new or low-hour, or if you live in a hot climate where SAE 30 or 10W-30 is recommended. For the price, it’s a solid value for extending the life of an aging engine.
