A generator is only as good as the stuff that you put into it. Without proper fuel and other pieces, a Honda generator will not perform to the best of its abilities. Even more concerning, it won’t last for as long as it should. What we’re here to focus on, Honda inverter generator oil, is essential to maintaining quality.

What type of oil should I be using for my Honda generator?
You should use 10W-30 motor oil for your Honda generator. Determining what type of oil to use largely comes down to viscosity, or how thick it is.
The first number, 10, refers to how thick it is in cold temperatures. W stands for winter (when it’s cold). The second number, 30, refers to how its composition in warmer temperatures. Regardless of the temperature, this type of oil works for whatever conditions you find yourself in.
Luckily, this is one of the most common types of oil. You can find it anywhere, though we emphasize purchasing name brands. A generator is an expensive machine. Because of this, we recommend high quality oil. With premium oil, the generator has its best chance to work at maximum efficiency for the longest amount of time.
Do you put a different type of oil in weaker or stronger generators?
Regardless of power provided by your generator, the type of oil remains the same. If you have the Honda EU1000i, Honda EU2000i, Honda EU3000, or any one of their other inverter generators, the story stays the same.
Amount of oil, however, will change since engine size changes. With a larger engine, you have a larger tank for oil. With a smaller engine, you need less oil—you get it.
One reason we love Honda is due to the resources they make available (for free) to their customers online. If you have a question about your specific generator, there is a manual with more information than you could ever need on the Honda website. Besides individual manuals, they provide recommendations for maintenance, general care and safety.
What else do I need to know about oil?
- You should check your oil level every time you use your generator
- Turning the fuel valve to OFF ensures that no oil gets into the engine
- Diluted oil could cause substantial damage to the engine

Changing the oil for a Honda generator
Everyone’s favorite task with any engine: changing the oil. We won’t go incredibly in-depth, but will give you the basics. If you want the deluxe version, check out this article.
If you can’t tell where the oil even goes in, that’s because it’s under a cover (which is really easy to remove). A critical element, you cannot change the oil if it is cold or hot, only warm. To accomplish this, briefly turn the generator on.
From here it’s pretty simple. Drain the oil. Add more oil. Put everything back together. Presto, oil changed.
‘Oil Alert’ system
We aren’t perfect, no one is. When it comes to using a generator, our mind can be in a million places. Whether you’re using it after a storm and you’re without power, or enjoying some quality time on a camping trip, things get complicated. Bottom line, you don’t have time to pay attention to every little detail.
To help protect your generator, Honda includes an Oil Alert system. When oil levels get critically low, this system triggers an indicator light and turns the engine off. In doing so, any damage to the engine or generator as a whole is prevented.
On generators of lesser quality, there are no shutoffs that prevent damage. Even if there is no immediate damage, it is detrimental to the long-term health of the machine. Honda is a few steps ahead, helping out as you spend your energy elsewhere.
Honda put out a great video via YouTube that discusses the oil change procedure.

Common Questions and Answers about Honda Generator Oil
Generators work on many of the same principles that car engines do, and just like cars they require oil to run correctly. Making sure that your generator has the right oil (and right amount) will increase its efficiency and make sure it lasts as long as possible. Here’s what you need to know about generator oil for your Honda generator:
Do Honda generators come with oil?
No. Honda generators do not come with oil. You will need to purchase oil separately and add oil prior to using your new Honda generator.
What type of oil does a Honda EU2000i 2200 generator take?
If you have a Honda EU2200i generator, it needs to use SAE 10W-30 oil.
Can I use synthetic oil in my Honda generator?
If you have a Honda generator, you can use synthetic oil in it. However, if you have a brand-new generator, make sure that you check the owner manual and run the engine with conventional oil first.
How much oil does a Honda generator take?
The amount of oil that your Honda generator will require depends on its size. If you have the EU3000i, for example, you may end up using a little more than half a quart of oil. Other generators may use a little less than half a quart.
How long does oil last in a generator?
If you have a generator, you are going to need to change the oil often. Typically, generator oil will last around 50 hours of runtime before needing replaced. Make sure to read the owner’s manual though because each generator is different.
How often should I change the oil in my Honda generator?
Generators go through oil pretty quickly, so you want to make sure that you stay on top of changing it. If you have a new generator, you will need to change the oil after the first 24 hours of use. After that, you typically need to change it after every 50-60 hours of use time.
Can I use car oil in my generator?
The type of oil that goes into your generator is the same stuff that goes into a car. You just want to make sure that the oil you are putting in your generator is the correct weight. 10W-40 oil for your vehicle should not be used in a generator that requires 5W-30 oil.
Can I use 10w40 in my generator?
The type of oil that you use in your generator will depend on how it was manufactured. Check the owner’s manual to see if 10W-40 is suitable for your engine.
How do I change the oil in my Honda 5000 generator?
Changing the oil on a generator is not difficult. Simply remove the drain plug and washer as well as the oil filler cap and drain the oil. Reinstall the plug and washer, refill your oil, and cap it back off.

Improper engine oil maintenance is another common mistake which can lead to poor lubrication. This can cause premature wear on your generator's engine internal parts, and can eventually result in permanent engine damage and generator failure.Can I use 10w30 synthetic oil in my generator? ›
10W-30 FULL-SYNTHETIC GASOLINE GENERATOR ENGINE OIL
10W-30 GENERATOR OIL is recommended for all RV gasoline generators. It is formulated for severe temperatures and its 10W viscosity at low temperatures allows it to replace conventional SAE 30 oils in RV gasoline generators.
Generally, running your generator in extremely cold temperatures will require a lower-viscosity oil, such as 5W-30, to ensure it will start. If your oil is too viscous during winter, the cold will make it thick, and it won't move around the engine well.How many hours can you run a portable generator before changing oil? ›
Experts recommend that you do a full oil change after every 100 hours of use, particularly if you're running your generator every day or over an extended period. For safety's sake, make sure you let the generator cool down before you do the oil change.Is 20W 50 oil good for generator? ›

More likely than not, you'll need an SAE 10W-30 oil type. SAE stands for Society of Automotive Engineers, who created the grading system. The 10 in 10W shows how well the oil can be pumped at cold temperatures, and the W stands for the word “winter.”
SAE 30 is a thicker oil best used in warm weather, while 10W30 is a thinner oil better for use in cold weather. SAE 30 will provide better lubrication for your lawn mower's engine, but it may cause the engine to run hotter. 10W30 will not lubricate the engine as well, but it will run cooler.What will happen if I put 10w30 instead of 5w30? ›
If you use 10w30 oil in a car that's designed for 5w30, the oil may not flow as easily at lower temperatures. That can lead to increased wear on the engine, since the oil won't be able to lubricate as well. In extreme cases, it could even cause engine damage.Should you use thicker oil in an older engine? ›
Many older, high mileage engines might face issues with oil pressure due to age and wear and tear. In this case, a practical method to improve oil pressure is to use a thicker oil, since the thicker oils have heavier base weight oil, which can help protect worn engine bearings well.Can I use 10W40 instead of 15W40 in my generator? ›
The difference between 10W40 and 15W40 is largely academic. Swopping one for the other will not do any actual harm to your engine. It just may not perform optimally. The first number is the winter number and the 10 is slightly more suited to slightly colder starting temperatures than the 15.Which oil is better 10W30 or 10W40? ›
Between a 10W-30 and 10W-40, 10W30 motor oil would run smoother in colder climates while a 10W40 would be more effective in preventing engine wear and tear in warmer temperatures.Can you mix different brands of oil with the same weight? ›
THE ANSWER IS NO!
Even if two different brands of oil have the same viscosity, you still should not be mixing them together.
Answer: This is a very contentious and well-worn subject, but there is actually no wrong answer. There is no downside to going with 10W-30 or 20W-50 motor oil in your engine. It really comes down to personal preference.How long can Gas sit in generator? ›
When you add a properly formulated fuel stabilizer and store your generator in a cool, dry place, gasoline in the fuel tank has a maximum shelf life of up to one year. However, gasoline will clog in the carburetor if it isn't used or drained within two weeks.Is SAE 30 the same as 10w30 for generator? ›
10w30 is thinner than SAE 30. The “30” means that it has the same viscosity as the other when the engine is hot. However, since it is thinner, it will never become as thick as SAE 30 when it gets cold. 10w30 has a viscosity of 10w which means it will start moving and protecting engine parts at a colder temperature.What oil do Harbor Freight generators use? ›
STP® Premium Small Engine 4-Cycle Oil SAE 10W-30 is specially formulated for use in generators and outdoor power equipment.
Yes. 5w30 and 10w30 are both 30 weight oils and the exact same thickness in your engine when it is at operating temperature.How many days straight can you run a generator? ›

Once all the old oil is drained, insert the funnel in the fill tube and refill the engine with Honda Power Equipment Oil. The Honda EU2000i has an oil capacity of . 42 quarts. Bring the oil level to the upper limit of the oil fill tube neck.
Since 10W-30 is thinner than 15W-40, its film strength can be weaker and it can be more prone to oxidation. Therefore, high quality additives are needed to compensate for those weaknesses in order for 10W-30 to protect as well and last as long as 15W-40.What does SAE 40 stand for? ›
Introduction of SAE 40 & SAE 50 Diesel Engine Oil
Here, SAE represents Society of Automotive Engineers and 40 alludes to the consistency of the oil. In layman's term, we can say 40 is the thickness of the oil. More is the thickness, lesser is the contact between metals, which expands the life of engine motor.
What is more, you can even use 5W30 oil instead of 10W30 in your generator or car engine, if needed. Both these types of oil have the same viscosity and this means that the oil will perform the precise same way once it reaches operating temperature and therefore can be used interchangeably.Can I use 10w30 instead of SAE 30 in my generator? ›
