Toro Engine Oil 4 Cycle 8Oz -139-0628

What It Is

This is an 8-ounce bottle of Toro 4-cycle engine oil (part 139-0628), a pre-measured SAE 30-weight oil designed for topping off or performing small oil changes on Toro walk-behind mowers, trimmers, and other 4-cycle outdoor power equipment.

Fitment & Compatibility

Before buying, confirm your engine requires SAE 30 weight oil (not synthetic or multi-viscosity). This oil is OEM Toro, but it’s compatible with most 4-cycle engines that call for SAE 30, including Briggs & Stratton, Honda, and Kawasaki. Check your owner’s manual for oil capacity—this 8 oz bottle is enough for most small engines (typically 15-20 oz total capacity). For larger decks (over 22 inches) or engines with higher capacity, you may need two bottles. It fits Toro models like Recycler, Super Recycler, and TimeCutter, but always verify your specific model number.

Key Things to Know

• Quality: SAE 30 is a straight-weight oil, not synthetic. It’s fine for warm-weather mowing but thickens in cold temps—avoid use below 40°F.
• Installation Difficulty: Easy. No tools needed—just unscrew cap, pour into oil fill tube, and check dipstick. Overfilling can cause smoke or damage.
• Common Gotchas: This is a small bottle (8 oz), not a full quart. Many mowers need 15-20 oz, so buy two if doing a full change. It’s not suitable for 2-cycle engines or 4-cycle engines that require 10W-30 or synthetic blends.
• Storage: Keep sealed and store in a cool, dry place. Oil degrades over time—use within 2-3 years.

Should You Buy It

Buy this if you need a quick, OEM-approved top-off for your Toro mower and prefer the convenience of a pre-measured bottle. It’s also a solid choice for a single small-engine oil change, but for larger engines or multiple machines, a quart of generic SAE 30 will save money.
