What Is the Best Generator Oil to Use?

When a storm knocks out the power to your home, a portable generator powers your furnace for heat, stove to cook, and other appliances. If you’re out camping, then a generator provides power for lights and other camping equipment.

There are many reasons why someone would want a portable generator, but if you want it to work properly for many years, then you need generator oil. Most generators are powered by fossil fuels such as natural gas or diesel fuel.

They use internal combustion engines that create electricity and oil keeps the engine lubricated. We’ll examine the best generator engine oil for your generator.

Check the User Guide About Engine Oil

Every portable generator has a user’s manual that explains the various parts of the machine and how it works. It likely has a section on the type of oil you need. It may not provide a specific brand unless the company that made the generator also makes oil.

This gives you a starting point in your search for the best oil for your generator. It should provide information about the type and viscosity of the oil. Once you have that, you can go online and start looking for the brands.

What Type of Engine Do You Have?

All internal combustion engines require some type of oil, but what kind depends on the type of engine. There are two primary types, 4-stroke engines, and 2-stroke engines. Most generators use a 4-stroke engine, but it’s best to make sure.

A 4-stroke engine is more complicated than a 2-stroke and creates more torque at lower revolutions per minute. A 2-stroke engine works at higher revolutions per minute and wears out faster because of it.

You might not be able to tell visually the difference between the two, but a 2-stroke engine is louder and has a distinctive buzzing sound because of the high revolutions per minute. Most 4-stroke engines use either 5W-30 or 10W-30 oils.

Viscosity and Operating Temperature

When choosing a generator oil type, you need to understand viscosity and operating temperature. Viscosity is the resistance to flow, and a higher viscosity means a higher resistance to flow. Oil lubricates the engine’s moving parts, so you want an oil with a lower viscosity.

The higher the oil viscosity, the higher the temperature of the engine. The W in the oil stands for winter and if you plan on using the generator in colder temperatures, you’ll want a 5W. If you plan on using it at a higher temperature, then you’ll want the 10 W.

Pick Brands You Know

Just because the oil says 10W-30, doesn’t mean it’s the best for your generator. Stick to well-known brands with a reputation for quality like those on sperrs.com and stay away from cheaper no-name brands. The oil could have contaminants that may end up damaging the engine.

Pick The Best Generator Engine Oil

Your generator oil has a lot to do with the longevity of your portable generator. Use the information in this guide to help decide which brand is right for your engine.
