D170 Oil Change Kit for John Deere Z425 Tune Up Kit, D150 D160 LA155 LA165 LA175 Maintenance Kit, 100 Series Zero Turn Lawn Mower Accessories Parts

What It Is

This is an all-in-one oil change and tune-up kit for John Deere Z425, D150, D160, D170, LA155, LA165, and LA175 lawn tractors, plus 100-series zero-turn mowers. It includes oil, filter, spark plug, and air filter—everything needed for a seasonal maintenance refresh.

Fitment & Compatibility

Before buying, confirm your mower’s engine model (usually stamped on the valve cover or engine shroud). This kit is designed for Briggs & Stratton engines commonly found on the listed Deere models—not Kawasaki or Kohler engines. Check your owner’s manual for the exact oil capacity (typically 1.5–2 quarts) and spark plug gap spec (usually 0.030”). The kit includes 1 quart of SAE 30 oil; you may need a second quart if your engine holds more. Measure your current air filter and spark plug dimensions to match—this kit uses standard sizes for those Deere models, but aftermarket variations exist.

Key Things to Know

• Quality: Branded as D170, this is a non-OEM kit. Filters and plugs are generic, but ratings (4.9/5) suggest decent reliability for the price.
• Installation difficulty: Easy—about 20 minutes for a beginner. Drain oil, swap filter, replace plug and air filter. No special tools needed beyond a socket set and oil pan.
• Gotcha: The included oil may not meet API service ratings for newer engines (check for “SM” or higher). If your mower is under warranty, use John Deere OEM parts to avoid voiding it.
• Gotcha: The spark plug may be pre-gapped, but always verify with a feeler gauge—wrong gap causes hard starts or misfires.

Should You Buy It

Perfect for DIY owners of the listed John Deere models who want a budget-friendly, one-box solution for annual maintenance. Avoid if you need OEM-specific parts for warranty compliance or have a non-Briggs engine.
