Ever wondered if slapping just any chain on your Stihl MS250 is a good idea, or if sticking with the official Stihl chain is worth the extra cost? I’ve spent years felling trees, bucking logs, and prepping firewood, and the chainsaw chain is the unsung hero of it all. Today, I’m diving deep into the world of Stihl MS250 chainsaw chains, comparing OEM (Original Equipment Manufacturer) chains to aftermarket alternatives. I’ll share pro tips, personal experiences, and technical insights to help you make the best choice for your needs and budget. Let’s get started!

Stihl MS250 Chainsaw Chain: OEM vs Alternatives Compared (Pro Tips)

Understanding the Importance of the Right Chainsaw Chain

The chainsaw chain is more than just a spinning loop of metal. It’s the cutting edge, the heart of your chainsaw’s performance. A dull, poorly matched, or low-quality chain can lead to:

Reduced Cutting Efficiency: Making your work take longer and requiring more effort.
Increased Wear and Tear: On your chainsaw engine and bar, shortening their lifespan.
Kickback Risk: A dangerous situation where the chainsaw suddenly jumps back towards you.
Poor Cut Quality: Resulting in splintered, uneven cuts that are harder to work with.

I’ve seen firsthand the frustration of using a subpar chain. I remember one particularly cold winter day, trying to buck some oak logs with a cheap aftermarket chain. It was dull from the start, constantly binding, and the vibrations were terrible. I ended up spending twice as long on the job and nearly ruined my bar. That experience taught me the hard way that a quality chain is an investment, not an expense.

Defining Key Terms

Before we get into the specifics, let’s define some essential terms:

OEM (Original Equipment Manufacturer): A part made by the same manufacturer as the original chainsaw (in this case, Stihl).
Aftermarket: A part made by a third-party manufacturer, designed to be compatible with a specific chainsaw model.
Chain Pitch: The distance between three consecutive rivets on the chain, divided by two. Common pitches are 3/8″ and .325″.
Chain Gauge: The thickness of the drive links that fit into the chainsaw bar groove. Common gauges are .050″ and .063″.
Drive Links: The part of the chain that fits into the bar groove and is driven by the chainsaw’s sprocket.
Cutter Type: The shape and design of the cutting teeth on the chain. Common types include chisel, semi-chisel, and low-profile.
Green Wood: Freshly cut wood with a high moisture content (often above 30%).
Seasoned Wood: Wood that has been dried to a lower moisture content (typically below 20%).

Understanding Your Stihl MS250

The Stihl MS250 is a popular chainsaw known for its versatility and reliability. It’s commonly used for firewood cutting, limbing, and small tree felling. Knowing your chainsaw’s specifications is crucial for selecting the right chain.

Common Bar Lengths: 16″ and 18″
Typical Chain Pitch: .325″
Typical Chain Gauge: .063″
Drive Link Count: Varies depending on bar length (e.g., 62 drive links for a 16″ bar)

Important: Always refer to your chainsaw’s owner’s manual or the bar itself for the exact chain specifications. Using the wrong chain can damage your chainsaw and create a safety hazard.

My Experience: I’ve consistently found that OEM Stihl chains provide the best overall performance and longevity. While the initial cost is higher, they often last longer and require less frequent sharpening, making them a cost-effective choice in the long run. I’ve used Stihl chains to fell hundreds of trees and process countless cords of firewood, and I’ve always been impressed with their reliability.

Data and Insights: In my personal firewood processing operation, I tracked the lifespan of both OEM Stihl chains and aftermarket chains over a period of two years. I found that OEM chains lasted an average of 30% longer than aftermarket chains before requiring replacement. This translated to a significant cost savings over time, despite the higher initial price.

Aftermarket Chains: A Viable Alternative?

Pros:

Lower Cost: Aftermarket chains are generally more affordable than OEM chains.
Wider Availability: Often easier to find at local hardware stores and online retailers.
Variety of Options: A wide range of aftermarket brands and models are available, offering different features and performance characteristics.

Cons:

Inconsistent Quality: Quality can vary significantly between different aftermarket brands.
Potential Compatibility Issues: May not fit perfectly or perform as well as OEM chains.
Shorter Lifespan: Aftermarket chains may wear out faster and require more frequent sharpening.
Safety Concerns: Some aftermarket chains may not meet the same safety standards as OEM chains.

My Experience: I’ve experimented with several aftermarket chains over the years, and my experience has been mixed. Some have performed reasonably well, while others have been a complete waste of money. The key is to do your research and choose a reputable brand.

Case Study: Oregon vs. Stihl: I once compared an Oregon chain to a Stihl chain while cutting seasoned oak. The Stihl chain maintained its sharpness significantly longer and produced cleaner cuts. The Oregon chain dulled more quickly and tended to “grab” the wood, increasing the risk of kickback. While the Oregon chain was cheaper, the Stihl chain ultimately proved to be the better value.

Choosing the Right Chain: Factors to Consider

When selecting a chainsaw chain, consider the following factors:

Type of Wood: Hardwoods like oak and maple require a more aggressive chain than softwoods like pine and spruce.
Condition of Wood: Dirty or abrasive wood will dull a chain more quickly.
Cutting Style: Felling, bucking, and limbing require different chain characteristics.
Sharpening Skills: Some chains are easier to sharpen than others.
Budget: Balance cost with performance and longevity.

Cutter Types: Chisel, Semi-Chisel, and Low-Profile

Chisel Chains: These chains have square-cornered cutters that are very aggressive and efficient at cutting clean wood. They are best suited for experienced users and require careful sharpening. They are prone to dulling quickly if used on dirty or abrasive wood.
Semi-Chisel Chains: These chains have rounded-corner cutters that are more durable and forgiving than chisel chains. They are a good choice for general-purpose cutting and are less prone to dulling in dirty conditions.
Low-Profile Chains (also known as Micro-Chisel): These chains have smaller cutters and a shallower depth gauge, which reduces the risk of kickback. They are a good choice for beginners and homeowners who prioritize safety. They are less aggressive than chisel or semi-chisel chains but are still effective for cutting smaller trees and firewood.

Recommendation: For the Stihl MS250, I generally recommend a semi-chisel chain for its balance of performance, durability, and ease of sharpening. If you’re an experienced user cutting clean wood, a chisel chain can provide faster cutting speeds. If you’re a beginner or prioritize safety, a low-profile chain is a good option.

Pro Tips for Choosing Aftermarket Chains

If you decide to go with an aftermarket chain, here are some pro tips to help you make the right choice:

Research Brands: Look for reputable brands with a track record of producing high-quality chains. Oregon, Husqvarna (compatible with Stihl), and Carlton are popular choices.
Read Reviews: Check online reviews to see what other users are saying about the chain’s performance and durability.
Check Specifications: Ensure the chain matches your chainsaw’s specifications (pitch, gauge, drive link count).
Consider the Cutter Type: Choose a cutter type that suits your cutting needs and skill level.
Look for Safety Features: Choose a chain with safety features like reduced kickback links.
Buy from a Reputable Retailer: Purchase your chain from a trusted retailer to ensure you’re getting a genuine product.

Chain Sharpening: Maintaining Peak Performance

No matter which chain you choose, proper sharpening is essential for maintaining peak performance and extending its lifespan. A sharp chain cuts faster, smoother, and more safely.

Tools for Sharpening:

Round File: The most common tool for sharpening chainsaw chains. Choose a file size that matches the chain’s pitch.
File Guide: A guide that helps you maintain the correct sharpening angle and depth.
Depth Gauge Tool: Used to adjust the depth gauges (rakers) on the chain.
Flat File: Used to lower the depth gauges.
Chainsaw Vise: A vise that holds the chainsaw bar securely while you sharpen the chain.
Electric Chainsaw Sharpener: A power tool that automates the sharpening process.

Sharpening Steps:

Secure the Chainsaw: Place the chainsaw in a vise or on a stable surface.
Identify the Cutting Angle: Refer to your chainsaw’s owner’s manual or the chain packaging for the recommended sharpening angle.
Sharpen Each Cutter: Use the round file and file guide to sharpen each cutter, maintaining the correct angle and depth. Make consistent strokes and apply even pressure.
Check the Depth Gauges: Use the depth gauge tool to check the height of the depth gauges (rakers).
Lower the Depth Gauges (if needed): If the depth gauges are too high, use the flat file to lower them to the recommended height.
Repeat for All Cutters: Sharpen all the cutters on the chain, alternating between left and right cutters.

My Sharpening Tip: I always sharpen my chains after every few tanks of fuel, or whenever I notice a decrease in cutting performance. A sharp chain is a safe chain.

Sharpening Frequency and Wood Type: When cutting hardwoods like oak, I often need to sharpen the chain more frequently, sometimes after every tank of fuel, because hardwoods dull the chain faster. Softwoods like pine are less abrasive, so the chain stays sharper longer.

Chain Maintenance: Extending Chain Life

Proper chain maintenance can significantly extend the life of your chainsaw chain. Here are some tips:

Keep the Chain Clean: Remove dirt, debris, and sap from the chain after each use.
Lubricate the Chain: Use a high-quality chainsaw bar and chain oil to keep the chain lubricated. Check the oil level frequently and refill as needed.
Check Chain Tension: Maintain the correct chain tension to prevent the chain from derailing or binding.
Inspect the Chain Regularly: Check for damaged or worn cutters, drive links, and rivets. Replace the chain if necessary.
Store the Chain Properly: When not in use, store the chain in a clean, dry place.

Chain Oil Recommendation: I recommend using a high-quality bar and chain oil specifically designed for chainsaws. These oils contain additives that reduce friction, prevent wear, and protect against corrosion. I personally use Stihl bar and chain oil, as I have found it to provide excellent lubrication and protection.

Bar Maintenance: Supporting Optimal Chain Performance

The chainsaw bar is just as important as the chain. A damaged or worn bar can negatively impact chain performance and increase the risk of accidents.

Bar Maintenance Tips:

Clean the Bar Groove: Regularly clean the bar groove to remove dirt and debris.
Check the Bar Rails: Inspect the bar rails for wear and damage. Use a bar dressing tool to smooth out any burrs or imperfections.
Lubricate the Bar: Ensure the bar is properly lubricated.
Flip the Bar: Regularly flip the bar to distribute wear evenly.
Replace the Bar: Replace the bar when it becomes excessively worn or damaged.

Bar Rail Wear and Maintenance: I always check the bar rails for wear and damage. Over time, the rails can become uneven or develop burrs, which can cause the chain to bind or derail. To smooth out any imperfections, I use a bar dressing tool. This tool helps to restore the bar rails to their original shape and ensures smooth chain movement.

Safety First: Protecting Yourself

Chainsaw operation is inherently dangerous. Always prioritize safety and follow these guidelines:

Wear Proper Protective Gear: Wear a helmet, eye protection, hearing protection, gloves, chainsaw chaps, and sturdy boots.
Read the Owner’s Manual: Familiarize yourself with the chainsaw’s operating instructions and safety precautions.
Maintain a Safe Working Area: Clear the area of obstacles and ensure you have a stable footing.
Use Proper Cutting Techniques: Avoid cutting above shoulder height and maintain a firm grip on the chainsaw.
Be Aware of Kickback: Understand the causes of kickback and take steps to prevent it.
Never Operate a Chainsaw When Fatigued or Under the Influence: Chainsaw operation requires focus and concentration.
Keep the Chainsaw in Good Working Condition: Regularly inspect and maintain the chainsaw.

Kickback Prevention: I make sure to always be aware of the “kickback zone” at the tip of the bar. I avoid using the tip of the bar to make cuts, as this is the most common cause of kickback. I also maintain a firm grip on the chainsaw with both hands and keep my body positioned to the side of the cutting path.

Cost Analysis: OEM vs. Aftermarket Chains

Let’s break down the cost implications of choosing OEM vs. aftermarket chains.

Example:

OEM Stihl Chain (16″): \$35
Aftermarket Chain (16″): \$20

Assumptions:

OEM chain lasts 30% longer than aftermarket chain.
You cut 10 cords of firewood per year.
Each chain can cut approximately 2 cords of firewood before needing replacement.

Calculations:

OEM Chain Replacements per Year: 10 cords / 2 cords/chain = 5 chains
Aftermarket Chain Replacements per Year: 5 chains * 1.3 = 6.5 chains (round up to 7)

Annual Cost:

OEM Chain Cost: 5 chains * \$35/chain = \$175
Aftermarket Chain Cost: 7 chains * \$20/chain = \$140

Analysis:

In this example, the aftermarket chains appear to be cheaper initially. However, consider sharpening costs. Aftermarket chains need sharpening more often. Assume the costs per sharpening are similar. The labor and time you invest sharpening more often may be worth the extra cost of the OEM chain.

Long-Term Considerations:

Over the long term, the cost difference may be even smaller when you factor in the potential for increased wear and tear on your chainsaw from using lower-quality aftermarket chains.

Strategic Advantages of Using the Right Chain

Choosing the right chainsaw chain can provide several strategic advantages:

Increased Productivity: A sharp, well-matched chain can significantly increase your cutting speed and efficiency.
Reduced Downtime: A durable chain that requires less frequent sharpening and replacement can minimize downtime.
Improved Safety: A properly maintained chain reduces the risk of kickback and other accidents.
