STIHL MS 172 C-E Gas Chainsaw 16-Inch (31.8cc)

The STIHL MS 172 C-E is a compact 31.8 cc gas chainsaw built for homeowners who need a dependable saw for occasional yard work, pruning, and small firewood jobs. Its light overall weight and ErgoStart pull system make it approachable for anyone picking up a chainsaw for the first time.

Effortless starting when you need it most

STIHL's ErgoStart system reduces the pull force needed to get the engine running, so cold mornings and repeated restarts in the yard don't turn into a workout.

A 2-MIX engine tuned for efficiency

The STIHL 2-MIX engine delivers strong cutting power from a small displacement while keeping fuel consumption and exhaust output low, so you spend less time refueling and more time cutting.

Tool-free adjustments save time

Side-access, tool-free chain tensioning and bayonet-style fuel and oil caps mean routine maintenance and mid-job adjustments don't require a separate toolkit.

Built to protect the operator

An anti-vibration system isolates the engine and cutting attachment from the handles, reducing fatigue on the hands and arms during longer sessions.

Frequently asked questions

What fuel mix does the MS 172 C-E need?

It runs on a 50:1 mix of unleaded gasoline and STIHL two-stroke engine oil; using the wrong ratio or straight gasoline can damage the engine.

Is this saw suitable for a first-time chainsaw owner?

Yes. Its lighter weight, easier-pull starting system, and tool-free adjustments make it a practical entry point for homeowners handling occasional cutting tasks.

What size branches or logs can it handle?

With a 16-inch bar, it comfortably handles pruning, small tree felling, and firewood rounds up to roughly 14-15 inches in diameter.

How often does the chain need tensioning?

Check tension before each use and periodically during longer jobs; the tool-free side-access adjuster makes this a quick, no-wrench task.
