This is a brand that is known for producing engine oil for most trucks. You will find it in most Dodge pickup trucks and this is a testament to its quality.

The brand we have described is the thickest in their line of motorized engine oil and it will work just fine in with your generator. 

The thick engine oil is designed to offer superior engine protection for RV generators as you are exposed to some extreme temperatures. It is however, best suited for higher watt generators that require thicker oil. The reason for thicker oil is to reduce the loss of oil via the process of oxidation. Oxidation is not good as when it happens it makes oil thinner and this causes it to lose its lubrication abilities. Without this extra layer of protection your engine will suffer from premature wear and tear. 

What we liked:

  • High viscosity making it suitable for higher watt generators
  • Reduces engine wear and fuel consumption 
  • Provides maximum protection against tear
  • Comes in an ergonomical container

Buying Guide for Best oil for Honda eu2200i generator 

The Honda eu2200i is a powerful generator suitable for those camping or for use in your home when their blackouts. Like most equipment your generator needs an oil change occasionally to keep things well lubricated. Oil is the lifeblood of any motorized engine and getting the right motor oil is vital if your machine is going to be operating efficiently. Here are some key factors you should consider when purchasing the right motor oil for your generator. 


One of the things you will note whenever you go searching for motor oil are these numbers on the surface of the container. The numbers indicate the viscosity of the oil. What this means is how well the oil pours under certain temperatures. The first number to your left indicates its viscosity during cold weather and the one to your right is for hot temperatures. Motor oil with high viscosity will pour out slower in cold weather. If motor oil loses its viscosity then it is not act out its properties as a lubricate well. It is important that you check your generator manual for the right viscosity number in this case it is SAE 10w 30. 


There are so many engine motor oil brands in the market and this makes shopping for the right one a bit tricky. One way to select oil is to go for the well known brands. These brands have had a longer period of time to establish themselves. Their oils are made under the stringent regulatory standards and this makes them to be of the best quality. You will find top brands like Castro, Shell, Pennzoil among others. If you can find a brand that matches your engine oil the better as it means the engine oil has being manufactured for that specific oil. In our case for the Honda eu2200i generator you do have a Honda motor oil which you can try out.


Motor oil is regulated and rated by various international bodies. This ensures it meets the highest level of standards and it is safe for the consumer. You should carefully examine the oil containers to ascertain which regulatory bodies have certified the oil.  You can also check out online reviews to see what other consumers are saying in regards to the oil.

Synthetic or conventional 

When it comes to the type of motor oil to use you will be confronted with two options – conventional or synthetic. The conventional oil tends to be the standard oil and is often cheaper than the synthetic one. It is tempting to use due to its cost but it may not provide you with the kind of protection you get with the synthetic ones. Synthetic oils are made from the highest form of standards and come with additives for engine protection and cleaning. As thus they are pricier than the conventional oils. You get more mileage on them and it is what we recommend for your generator. 


The Honda eu2200i generator is a portable generator that comes in handy to power your applications during camping or when experiencing blackouts. The best oil for this generator will have to be the Pennzoil 10w 30. We liked the motor oil due to its high viscosity which allows it to handle extreme weather conditions.

You should check your generator manual first to know what is permissible. If you do not have any specifications it is okay to use motor oil with the same viscosity.

Is the Honda eu2200i generator noisy?

The generator is not noisy hence making it an excellent companion for camping
