If you are using a chainsaw, keeping the bar and chain lubricated is very important. The DEWALT Biodegradable Bar & Chain Oil Lubricant is made for smoother cutting, less wear, and safer operation. It is also biodegradable, so it is safer for the environment compared to normal oil. I will explain what this oil is, the main advantages, the steps to use it, my own experience, and small things to keep in mind.
What This Oil Is
This is a DEWALT chain and bar oil designed for chainsaws. It reduces friction and heat while cutting. Because it is biodegradable, it breaks down naturally and does not harm soil or plants if it drips. The oil is formulated to stick to the chain and not fling off easily, so it keeps lubrication steady while sawing.

Advantages of DEWALT Bar & Chain Oil
1. Biodegradable Formula
It is eco-friendly and safer to use outdoors. If some oil drips on soil or wood, it breaks down naturally.
2. Smooth Cutting
The oil reduces friction and heat. The chain moves easier, and cuts feel smoother.
3. Reduces Wear
Lubrication helps the bar and chain last longer. It saves money because you don’t replace parts too soon.
4. Less Fling Off
The oil is made to stick better. It stays on the chain instead of spraying away.
5. Works in All Weather
The formula flows well in different conditions. It doesn’t get too thick in cold or too thin in heat.
Steps to Use DEWALT Bar & Chain Oil
Step 1: Check Oil Level
Before using your chainsaw, open the oil tank and check if it needs filling.
Step 2: Shake Bottle
Give the bottle a light shake so the oil is ready to pour.
Step 3: Fill the Tank
Pour the oil into the chainsaw oil reservoir. Do not overfill.
Step 4: Run the Saw
Start the chainsaw and let it run. The oil will spread along the bar and chain automatically.
Step 5: Refill as Needed
Keep checking the level during work. Refill when low so the chain never runs dry.
My Own Experience Using It
When I used this oil, the first thing I noticed was how smoothly the chainsaw ran. The chain moved faster with less effort. While cutting logs, I didn’t feel the chain dragging or heating up. After working for about an hour, the chain still looked well-oiled and not dry. I liked that it didn’t fling off much. Normally I see oil spray around the wood, but this stayed on the chain longer. Cleaning up after was also easier, and I felt better knowing it was biodegradable since I cut near garden beds.
Small Things To Keep In Mind
- It is biodegradable, but it is still oil. Don’t pour it directly into soil.
- Works best with regular refilling; a dry chain can still cause wear.
- It is made for chainsaws, not for other machines.
Who This Oil Is Good For
- Chainsaw users who want smoother cutting.
- People who care about using eco-friendly products in their yard.
- Homeowners who cut firewood or trim trees often.
- Anyone who wants their chainsaw bar and chain to last longer.
Final Verdict
The DEWALT Biodegradable Bar & Chain Oil Lubricant is a reliable and safer option for chainsaw maintenance. It saves money by protecting the bar and chain, it saves time by reducing friction for smoother cuts, and it saves worry because it is biodegradable. It might not replace heavy industrial oils for all machines, but for everyday chainsaw work, it is a strong choice. If you want your saw to run smoother and last longer while also being eco-friendly, this oil is worth using.
