You have a Generac generator and need to change or add oil. What type of oil should you buy?
Please Note: When you purchase a new Generac generator, it will not come with oil already in the engine. This is because there is a risk of oil spillage during shipment. If oil were to leak into other engine parts, it could cause serious damage. For this reason, you will need to purchase oil separately and add it to your generator before operating.

Types of Oil Explained
This article explains the types of oil for generator engines to understand how lubricant is categorized. Here is an excerpt:
Oils are rated by their viscosity. Viscosity is the thickness of the oil. The thinner the oil, the more fluid it will be in colder weather and the easier it moves when starting your engine. Heavier weight oil is needed in warm weather to protect the engine components.
The weight of your generator’s oil is just as important as the type of oil you use. The first number in the weight rating indicates the oil’s viscosity, or how fluid the oil is when exposed to friction during various outside temperatures. The lower the first number, the thinner the oil and the better suited it is for cold conditions.
The “W” in 10W-30, for example, stands for winter. The second number in the weight rating indicates the thickness of the oil when the engine is running at an average operating temperature. Therefore, 10W-30 means that the oil is moderately thin for average temperatures, making it the most commonly used type of oil.
However, depending on where you live and what kind of weather conditions you typically experience, you may need to use a different weight of oil. For example, if you live in an area with very cold winters, you may need to use 5W-30 or even 0W-30. On the other hand, if you live in a region with hot summers, you might be better off using 10W-40 or 15W-40. Ultimately, selecting the proper weight oil for your generator engine depends on a variety of weather factors.
Using Generac Recommended Oil Weight
To ensure your Generac Generator runs smoothly and efficiently, it is important to use the oil type recommended in your generator’s manual. Using the wrong oil for the season can damage the engine by increasing friction.
The right oil will help protect your engine from wear and tear and make sure it runs smoothly during operation. In addition, using the recommended oil weight will help to extend the life of your generator. By following these simple tips, you can keep your Generac Generator running like new for years to come.
FAQ
How many quarts of oil does a Generac generator take?
The amount of oil a Generac generator takes depends on the size of the generator. Engine oil capacity ranges from 1.1 to 1.9 quarts, so make sure you check your owner’s manual to determine the correct amount for your model.
Filling the oil tank is an important step in maintaining your generator, as it helps to keep the engine lubricated and running smoothly.
Can I use 10w30 in my Generac generator?
You can use 10W-30 in mild weather conditions. In temps under 40°F and above -10°F, you can use this type of oil. This is the official recommendation on the Generac website.
What kind of oil does a Generac 22KW generator take?
If you own a Generac 22KW generator, you need to use 5W-30 synthetic oil. This is a great oil for Generac generator engines, and it will help to keep your engine running smoothly. Synthetic oil is also more resistant to breakdown than a traditional oil, so it will last longer and keep your generator running at peak performance.
How often should I change the oil in my Generac generator?
The frequency will depend on how often you use the generator, but as a general rule of thumb, you should change the oil after the first 20-30 hours of operation and then every 100 hours after that. With a little bit of care, you can keep your generator running smoothly for years to come.
How do I reset my Generac generator after an oil change?
After changing the oil in your Generac generator, it is necessary to reset the “Maintenance Due” light. To do this, set the generator to the “OFF” position and press the “OFF” button. If there is an alarm condition present, you will need to clear it before resetting the light. Once everything has been reset, your generator should be ready to go.
