What Oil Can I Use On My Hedge Trimmer? 

SAE20 or 3-in-1 Multipurpose Engine Oil

This type of oil is better to be used in learn mowers and chainsaws. It has been specifically designed for small engines and provides excellent protection against wear and tear that comes with overuse and aging.

This oil can also prevent corrosion and rest while lubricating the blades properly. If you are looking for an oil that can withstand high temperatures and pressure, this is the oil to be used. 

Vegetable oil

If you are looking for an affordable option, then vegetable oil is the one. It is not only an easy option to lubricate the hedge trimmer but also one that will cause no harm to the plants.

However, you will find vegetable oil less influential than 3-in-1 multipurpose oil in the long run. If you want something that can withstand high pressure and high-temperature conditions, look at the other alternative lubricants available.

Olive Oil Or Canola Oil

You can also use natural oil as a lubricant for hedge trimmers. Oils like olive oil and canola oil offer the same benefits as vegetable oil but will not be able to keep it protected against corrosion, rust, and wear that comes with aging and overuse. However, you will find Canola oil and olive oil readily available in local stores nearby. It is better for temporary usage.

Silicone Spray Lubricant

It is relatively easy to find silicon spray lubricant in your home; if there is none, you can buy it from a local store. Silicone spray lubricant is designed to protect metal surfaces from moisture and rust damage.

It is also suitable for lubricating hedge trimmers. It is also widely available in most hardware stores and can be applied easily on the trimmer blades. Since it is a light lubricant, you will have no problem with dust and dirt accumulating on the blade/trimmer.

Air tool lubricants can extend the lifespan of tools like hedge trimmers and provide an excellent shield against rust and corrosion. It is specially designed to lubricate tools but will not work with any other device.

Chain Oil

Even though chain oil is considered a thick lubricant for tools like hedge trimmers, you can use it temporarily or urgently. The chain oil is specially designed to protect and lubricate change gears and sprockets of lawnmowers, tractors, and other heavy tools. Since it is already a heavy lubricant, you will find it very messy to apply on trimmers and clean it afterward.


Diesel can also lubricate your hedge trimmer if no other quick option is nearby. It may not be as strong as other lubricants, but you can keep the blades lubricated with diesel. Since it is harmful and explosive content, handle it properly. I wonder why people use diesel as a lubricant to oil their hedge trimmer, but few people have firm beliefs & debates on many forums.
