Method 1: Generator Break in Process
Just like in any other refurbished or new engine, your generator also needs to be broken in to increase its durability.

If you have just bought a new generator, you can make sure it runs fully efficiently by following this generator break in process.
1. Read the Manual
The first and most critical step in breaking in a new generator is to read the manufacturer’s instruction manual. Though many people have ideas about how to break in a generator, it is important to first read and follow the instruction manual to avoid voiding the warranty.
2. Fill the Oil Reservoir
The next step is to check the recommended oil type. Once you find out, remove the spark plug to add some oil conditioning fluid to the cylinder underneath. This helps dry out any moisture on the cylinder walls.
3. Add Fuel
Replenish the fuel reservoir with the recommended fuel. Make sure to follow the octane manuals to check if fuel addition is needed to increase the durability of your engine.
4. Start the Generator
Finally, start your generator and let it run for about 1 hour with no load. After this, change the oil and add an oil cleaning fluid.
To sum up this section, when you break in a new generator, make sure the rings and pistons within the engine wear grooves into the walls of the chamber. This ensures that all components in the generator are well lubricated. Check out best generator deals on Amazon here
Generator Break-In – How to Extend the Life of a Generator
Before you use your generator, it is recommended that you break-in it properly. A break-in is a critical step, as it prevents a dry start and metal debris from clogging the engine. You should always check the manufacturer’s manual before breaking-in your generator. If the manufacturer does not recommend a break-in, you can perform one yourself. This procedure is completely optional.

How to Break in a New Generator (Step by Step)
The first step in breaking in your new generator is to gather the parts that you need. You will need to collect the oil, gasoline, and gas for the new model. If the manual says you should use a specific brand of oil, do so. Also, you will need a funnel, preferably a large one, to make the process easier. After gathering all the materials, you will need to pull the starter cord five to ten times. This will lubricate the pistons and prevent dry starts.
Once you’ve gathered the parts, it’s time to begin breaking in the new generator. While this procedure will take some time, it is essential to ensure that all parts are in good condition. Then, you can prepare the unit for heavy use. This procedure should be completed within the first two to three hours of use. You’ll need to start by running the generator a few times to make sure it is working properly.
The next step in breaking in a new generator is to fill it with gas and oil. If you have a brand-new engine, you’ll need to fill it with the highest octane possible. In addition, you should use oil recommended by the manufacturer, and be sure to add oil conditioner to the gas. Once the fuel is full, you can begin breaking in the generator.
Method 2: How to Break in a Generator
Before you start your generator, it is vital to add oil and/or fuel to the crankcase. The amount of oil should be the maximum recommended by the manual. It is also recommended to run the generator without any load for the first hour, in order to allow the oil and gas to circulate. However, there are some precautions that you must take when breaking in a new generator. Make sure to follow all manufacturer guidelines, and you should not run the generator without any break-in oil.
Using break-in oil on a new generator is crucial for extending its life and preventing damage. The first hour of operation will make the oil dirty. A second run is not necessary, but some manufacturers recommend it. It is also recommended that you run the generator with a load of up to 500 watts for the first hour, to ensure that the engine is ready to handle a load.

The next step is to change the oil and gas in your generator. You can find out the exact steps in your manual. In most cases, manufacturers don’t provide information on how to break in a generator, other than telling you to change the oil immediately after starting the unit. In some instances, it’s not enough, and you’ll need to do it for a few hours. If you’re unsure, you can call a technician to help you with this. Read about why generator won’t start here.
