How to Choose the Right Chainsaw Oil: A 2024 Guide

How to choose the right chainsaw oil

Choosing the right chainsaw oil is crucial for optimal performance and longevity of your chainsaw. The oil lubricates and cools the chainsaw bar and chain as they operate, preventing excess friction and wear. Using the wrong oil, or oil that is too thin or thick, can lead to insufficient lubrication, increased component wear, overheating, and potential engine damage. 

Proper lubrication is vital for any chainsaw. Without oil, the fast-moving chain will quickly wear against the guide bar, leading to excess friction, overheating, and eventual failure. Chainsaw oil also helps flush away wood dust and debris and prevent corrosion on the bar and chain. Using the manufacturer recommended bar and chain oil is always advisable, as it is formulated specifically for chainsaw applications. But there are also suitable alternatives if needed, as long as you consider viscosity, tackiness, eco-friendliness, and other key factors.

In this chainsaw oil guide, we will cover the different types of chainsaw oils, considerations for selecting oil, seasonal recommendations, common oil substitutes, proper oil usage and maintenance, frequently asked questions, and final tips for choosing the right chainsaw bar and chain oil for your needs. Equipped with this information, you can make an informed decision to get the optimal performance and lifetime out of your chainsaw. Let’s get started!

How to Choose the Right Chainsaw Oil?

How to choose the right chainsaw oil

When selecting chainsaw oil, there are a few key factors to consider:

Types of Chainsaw Oils

There are a few primary types of oil designed specifically for chainsaw bar and chain lubrication:

Standard chainsaw oil

This conventional oil is formulated for optimal adhesion and lubrication under a range of conditions. Most chainsaw manufacturers recommend using standard bar and chain oil for best performance. These oils are designed to stick well and not fling off at high chain speeds.

Hydraulic chainsaw oil

Formulated for use in hydraulic equipment, these oils can also work for chainsaw lubrication. They have high tackiness to stick to the bar and chain.

2-stroke chainsaw oil

These oils are designed for 2-stroke engine lubrication and fuel mixing. They can work for the bar and chain in a pinch but are not optimal.

Bar and chain oil

These oils are specifically made for chainsaw bar and chain lubrication. They protect against rust, resist slinging off, and provide optimal lubrication.

Factors to Consider When Choosing Chainsaw Oil

When selecting chainsaw oil, consider the following factors:


The oil must provide sufficient lubrication and cooling for optimal performance. Standard bar and chain oils engineered specifically for chainsaws are best in this regard.


Oils made for chainsaw lubrication are more expensive but worth the cost for best performance. Alternatives like used motor oil can save money but may compromise efficiency.

Compatibility with your chainsaw

Check your owner’s manual for recommended oil types. Using the recommended oil ensures optimal performance in your specific model.

Environmental impact

Some standard oils use more eco-friendly plant-based additives compared to petroleum-based oils. Alternatives like vegetable oils are also more environmentally friendly.

Chainsaw Oil for Different Seasons

Outdoor temperature impacts chainsaw oil performance. Here are tips for seasonal use:

Summer Chainsaw Oil

Thicker oil for summer

In hot weather, thinner oils become less viscous and can fling off the chain more easily. Using a thicker oil in summer helps the oil better adhere to the chain at high temperatures.

Winter Chainsaw Oil

Thinner oil for winter

Colder temperatures thicken oil, slowing flow through the oiler system. Using slightly thinner oil in winter helps the oil continue flowing smoothly to lubricate the chain.

Chainsaw Oil Alternatives

While standard chainsaw oils are best, some alternatives can also work in a pinch:

Motor Oil

Pros and cons of using motor oil

Motor oils like 5W-30 or 10W-30 provide decent lubrication and are readily available. However, they lack optimal tackiness to stick to the bar and chain. Used motor oil is thicker and adheres better but can contain contaminants.

Vegetable Oil

Canola oil

Of vegetable oils, canola oil adheres best to the bar and chain. It’s readily biodegradable for eco-friendliness. However, vegetable oils lack optimal viscosity and lubrication for chainsaw applications.

Soybean oil & Olive oil

Other vegetable oils like soybean and olive oil can work but may not have enough tackiness or viscosity to properly lubricate the chain. Canola oil is typically the best vegetable oil option.

Hydraulic Fluid

Pros and cons of using hydraulic fluid

Like hydraulic chainsaw oils, standard hydraulic fluids also have high tackiness to adhere to the bar and chain. However, they may lack the optimal lubricating properties of dedicated chainsaw oils and need to be mixed with oil.

Chainsaw Oil Maintenance

Proper oil usage and maintenance ensures your chainsaw always has sufficient lubrication:

How to Add Bar and Chain Oil?

Steps to add oil to your chainsaw

  1. Locate the oil tank cap
  2. Use a funnel to carefully pour oil into the tank
  3. Replace cap securely, wiping any spills
  4. Check oil level window to confirm sufficient oil

How Much Bar Oil Should a Chainsaw Use?

Proper oil consumption

Most chainsaws use around 2-4 ounces of oil per tank of gas. Regularly check consumption and refill as needed. Oil flow rate can be adjusted on many models via an oil adjustment screw.

What Happens If You Run a Chainsaw Without Bar Oil?

Risks of running a chainsaw without oil

Without oil, the chain will quickly overheat from friction against the dry bar. This can damage the bar and chain. Running a chainsaw continuously with no bar oil can ruin the bar, chain, and engine. Always ensure sufficient oil.

Frequently Asked Questions

Can I use motor oil as a chainsaw oil substitute?

Yes, but with caution. Motor oils can work as a substitute but lack optimal viscosity and tackiness for sticking to the bar and chain at high speeds. Thicker used motor oil adheres better. Only use motor oil brands without additives.

Is vegetable oil a good alternative to chainsaw oil?

Yes, especially canola oil. Of vegetable oils, canola oil has optimal viscosity and tackiness to adhere and lubricate the chain. Though not as effective as dedicated oils, it provides eco-friendly lubrication in a pinch.

How often should I check and refill my chainsaw oil?

Regularly, depending on usage. Check the oil level with each use, and refill when down more than halfway. With frequent use, refill the oil tank every 1-2 gas tanks. Adjust oil flow rate as needed.

Can I use hydraulic fluid as a chainsaw oil substitute?

Like hydraulic chainsaw oils, standard hydraulic fluids have good tackiness to stick to the bar and chain for lubrication. However, they may lack optimal lubricating properties. Only use pure fluid, not premixed oil.

What are the environmental impacts of using alternative chainsaw oils?

Standard oils are petroleum-based, while some new oils use plant-based additives. Canola and other vegetable oils are readily biodegradable for reduced environmental impact.

How do I know if my chainsaw is using enough oil?

If your chainsaw bar and chain look dry, the chain stretches or squeals, or oil consumption is under 2 oz. per tank of gas, increase oil flow via the adjustment screw.

What are the risks of using the wrong chainsaw oil?

Insufficient lubrication and cooling from light or wrong oils can lead to overheating, accelerated wear, winter clogging, and damage over time. Only use recommended oils for your chainsaw.


Choosing the optimal chainsaw bar and chain oil is essential for performance and longevity. Consider oil type, tackiness, viscosity, and eco-friendliness for your needs and chainsaw model. While oil substitutes can work, dedicated chainsaw oils engineered for adhesion, rust prevention, and lubrication are always the best option for optimal saw performance in any season. Use the manufacturer-recommended oil, and maintain proper oil usage and levels. With the right oil and care, your chainsaw will run reliably for years of trouble-free use.
