AUC12916 Oil Filter for Compatible with E120- E180,S100-S180 Series Lawn Tractor (35-Second Easy)100 Series Lawn Tractor OEM（with oil）

What It Is

This is a replacement oil filter (model AUC12916) designed for John Deere 100 Series lawn tractors, specifically the E120–E180 and S100–S180 models. It’s a direct-fit spin-on filter that includes pre-filled oil for faster, less messy changes.

Fitment & Compatibility

Before buying, confirm your tractor’s model and engine type. This filter fits John Deere 100 Series with 20–24 hp V-twin engines (e.g., E120, E140, E170, S120, S180). It will not fit single-cylinder models like the E100, S100, or older 100 Series (e.g., L100, LX172). Check your owner’s manual or existing filter’s part number (OEM equivalent is John Deere AM125424 or AM116304). Measure the filter’s thread size (3/4″-16) and gasket diameter (approx. 2.6″) to match your engine’s mounting base. This is an aftermarket product, not OEM, so verify the listed compatibility with your specific engine (Briggs & Stratton, Kawasaki, or Yanmar) before ordering.

Key Things to Know

• Pre-filled oil saves time – The filter comes with oil inside, so you can install it directly without pre-filling. Just prime the system by cranking the engine with the spark plug disconnected for a few seconds.
• Installation is straightforward – Spin on by hand until the gasket contacts the base, then tighten ¾ to 1 full turn. No tools required, but check for leaks after starting.
• Quality vs. OEM – This filter uses a metal housing and standard filtration media. It’s fine for regular use, but if you have extended intervals or dusty conditions, an OEM or high-end aftermarket filter (e.g., Wix, Baldwin) may offer better bypass valve and media quality.
• Common gotcha – The pre-filled oil can drip during handling. Keep a rag handy and avoid over-tightening, which can strip the threads or warp the gasket.

Should You Buy It

If you own a compatible John Deere 100 Series tractor with a V-twin engine and want a quick, no-mess oil change, this filter is a convenient choice. It’s not the best for heavy-duty or commercial use, but for most homeowners with moderate mowing, it delivers solid value at $41.99.
