What It Is

The S100 Oil Change Kit is a complete maintenance set for 100 Series John Deere lawn tractors and select ZTrak zero-turn mowers. It includes an oil filter (AM125424), air filter, spark plug, and fuel stabilizer—everything needed for a single oil change and tune-up.

Fitment & Compatibility

Before buying, confirm your mower has a 100 Series frame or ZTrak model with a 17.5–22 HP single-cylinder engine (typically Briggs & Stratton or Kawasaki). Compatible models include D100, D105, D110, D125, D130, D140, E100, E140, S130, S140, Z335e, and Z315e. Check your current oil filter number—this kit uses AM125424 (OEM equivalent). Not for X300, X500, or 200 Series tractors. Measure your air filter housing to ensure the included filter matches (most 100 Series use a rectangular foam/pre-filter design).

Key Things to Know

• Quality: Filters and spark plug are aftermarket but meet OEM specs. Oil is not included—you’ll need SAE 30 or 10W-30 (about 1.5 quarts).
• Installation: Easy for DIYers. Drain oil, replace filter, swap air filter and spark plug, add stabilizer to fuel. No special tools required.
• Gotcha: The spark plug gap may not be pre-set—check and adjust to 0.030 inches. Also, the fuel stabilizer is a small single-use packet; use it all at once.
• Frequency: Designed for annual maintenance (every 50–100 hours). If you mow heavy or dusty conditions, replace air filter mid-season.

Should You Buy It

This kit is ideal for John Deere 100 Series or ZTrak owners who want a single, cost-effective package for routine maintenance. It’s a solid value if you prefer aftermarket parts over OEM (saves ~30–40%), but skip it if you need exact factory parts or have a larger-frame tractor.
