MTD Genuine Parts 28 oz. 4-Cycle Engine Oil

What It Is

This is MTD’s OEM 28 oz. 4-cycle engine oil, designed for 4-cycle lawn mower engines that require SAE 30 weight oil. It’s a straight-grade, non-detergent oil meant for small engines (push mowers, tractors, zero-turns) operating in warm temperatures.

Fitment & Compatibility

• Engine type: Only for 4-cycle engines. Do not use in 2-cycle (mix with gas) or 4-cycle engines requiring 5W-30, 10W-30, or synthetic blends.
• Capacity: 28 oz. bottle fills most push mower crankcases (typically 15–20 oz.) with leftover. Check your owner’s manual for exact oil capacity.
• Brand compatibility: MTD Genuine Parts oil fits any brand that uses SAE 30 (Briggs & Stratton, Tecumseh, Kohler, Honda, etc.) as long as the engine calls for straight 30-weight. Not limited to MTD machines.
• What to verify: Confirm your mower’s oil type (SAE 30 vs. multi-viscosity) and capacity. Also check if your engine requires a detergent oil—this is non-detergent, so avoid it in engines that specify detergent (rare, but check manual).

Key Things to Know

• Quality: MTD Genuine Parts oil meets API service classification SF/SG/CC, which is adequate for most older and current small engines. Not the highest tier (SM/SN), but fine for air-cooled mowers.
• Installation difficulty: Easy—just unscrew the oil fill cap/dipstick, pour in slowly, and check level. No special tools needed.
• Common gotcha: Non-detergent means it won’t hold contaminants in suspension. If your engine has sludge or carbon buildup, this oil won’t clean it. Use only in clean engines or those with a history of regular oil changes.
• Storage: Keep sealed until use; no expiration date, but store at room temperature away from moisture.

Should You Buy It

Buy this if you need a quick, affordable SAE 30 oil for a 4-cycle push mower or small tractor and want OEM quality without overpaying for synthetic. Skip it if your engine requires multi-viscosity or detergent oil, or if you need a full quart (you’ll have 8 oz. left over).
