LIQUI MOLY Top Tec 4200 SAE 5W-30 New Generation | 1 L | Fully synthetic engine oil | SKU: 2004

What It Is

LIQUI MOLY Top Tec 4200 SAE 5W-30 is a fully synthetic engine oil designed for modern lawn mower engines, especially those with four-stroke engines, catalytic converters, or extended oil change intervals. It’s ideal for residential and commercial mowers, zero-turn mowers, and garden tractors requiring a high-performance 5W-30 oil.

Fitment & Compatibility

• Check your owner’s manual for the recommended oil viscosity (SAE 5W-30) and API/ACEA specifications (e.g., API SN, ACEA C3). This oil meets many modern mower requirements but is not universal—older engines may need SAE 30 or 10W-30.
• Engine type: Four-stroke only. Not for two-stroke engines (no pre-mix).
• Brand/model fit: Works with Briggs & Stratton, Kohler, Kawasaki, Honda, and other common mower engines that specify 5W-30 synthetic. Cross-reference with OEM part numbers (e.g., Briggs & Stratton 12V-100 or Honda 08C35-A320G1).
• Capacity: 1 liter bottle. Most mower engines take 0.5–1.5 quarts (0.47–1.42 L). Confirm your mower’s oil capacity—buy multiple bottles if needed.
• Oil change interval: Follow mower manufacturer’s schedule (typically every 50–100 hours). This oil supports longer intervals in modern engines but don’t exceed the manual’s recommendation.

Key Things to Know

• Quality: Fully synthetic with high shear stability and excellent thermal resistance. Reduces engine wear, sludge, and deposits in high-heat mower operation.
• Installation difficulty: Easy—drain old oil, replace filter if applicable, fill to dipstick mark. No special tools.
• Common gotchas: This is a low-SAPS (sulfated ash, phosphorus, sulfur) oil, which is fine for most mowers but may not be needed for older engines without emissions controls. Overfilling can cause engine damage—measure carefully.
• Price vs. value: At ~$15.80/L, it’s premium-priced but often cheaper per quart than dealer-branded synthetic oils. One bottle typically covers a single change for most push mowers.

Should You Buy It

Buy it if you run a modern four-stroke mower that calls for SAE 5W-30 synthetic oil and you want top-tier protection for extended life, especially in hot or dusty conditions. Skip it if your mower requires conventional oil or a different viscosity (e.g., SAE 30) to avoid voiding the warranty or causing performance issues.
