How Much Oil Does a Generator Take?
Ideally, you need to be checking your oil regularly. If you’ve noticed that your generator seized up a few days after use, it’s usually because you’ve neglected to check the oil level.
Thankfully, modern generators come with a low oil shutdown feature that can prevent any real damage from occurring. So, if it has stopped, your first port of call should be to check the oil.
As a general rule, change your oil every 100 hours of use. Of course, make sure it has had a chance to cool down before you actually make the change. We don’t want any catastrophic injuries or accidents occurring!
You will find that most generators take between 500 to 800 millimeters of oil. But this depends on the size and the brand. While we aren’t going to be able to give you specifics per brand, we’ll do our best to answer your “how much oil does a generator take?” question.
Sound like a plan? Excellent!

No, this isn’t all the generators that Westinghouse makes. The brand sells larger ones too, however, we’re not going to be covering all the models of every brand.
Also, bear in mind that the user manual stipulates the importance of not overfilling it. Doing so can lead to lots of problems like fires, serious engine damage, and damage to surrounding property. So, before filling, ensure the generator is on a level surface. This way, the oil level reading will be as accurate as possible.

| P2200 PowerSmart | 500 ml |
| P2400 PowerSmart | 500 ml |

DuroMax generators are a bit different when it comes to finding the specific oil capacities in the owner’s manual. Unfortunately, it just doesn’t list it. Instead, you have to refer to the sticker on the generator itself. We found this a little strange and were hunting around for ages!
#4 Champion
| Champion Generator Model | Oil Capacity |
| 170cc Inverter | 560 ml |
| 224cc Inverter | 560 ml |
| 2000 Watt Inverter | 370 ml to 470 ml |
| 3500 Watt Inverter | 560 ml |
Disclaimer: Of course, you should always check the manual of your specific generator to know exactly how much oil to put into your model.
Champion is very helpful as their Customer Service Center tells you exactly how many quarts are required for all of their models. We’ve converted a few of the most popular ones to ml here for you. But take a look in your owner’s manual to read the specific instructions too.
#5 Firman

| ECO 4000 | 620 ml |
| ECO 4000RE | 620 ml |

Just like the Westinghouse, Firman emphasizes the importance of ensuring your generator is on a flat and level surface before filling to improve accuracy.

Disclaimer: Of course, you should always check the manual of your specific generator to know exactly how much oil to put into your model.
If you’re looking for your Ford generator’s oil capacity online, be careful not to fall into their cars’ oil capacity category. It’s quite easy to do, so make sure you check the headings before trying to cram 3.5 L of oil into your portable generator!
#7 Honda
| Honda Generator Model | Oil Capacity |
| EU2000i | 400 ml |
| EU1000i | 250 ml |
Disclaimer: Of course, you should always check the manual of your specific generator to know exactly how much oil to put into your model.
The Bottom Line
As you can see, the amount of oil needed for each generator changes drastically — even if they’re made by the same company. This is why we’ve been encouraging you to check your owner’s manual before going ahead and filling it up.
Remember, it isn’t just the oil amount that you need to be aware of, it’s the type of oil too. Viscosity plays a vital role in keeping your generator happy and healthy.
This will be stated inside the owner’s manual, as well as on the label of your generator. It’s best to know the specifics before you purchase it so you can have everything you need by the time it arrives.
