To change the oil on your EU2000i Inverter generator first run the unit until it's warmed up - turn it off and let it cool down for 30 minutes. Running the generator will heat the oil. The heated oil is thinner and will drain more easily and completely from the engine.
10 Easy Steps to Changing Oil
1. Secure the gas cap and turn the engine switch and vent lever to the off position. This will reduce the possibility of fuel leaking.
2. Remove the side cover by loosening the screw.
3. Remove the oil dipstick.
4. At this point you have two options. Pack the bottom of your generator with "rags" or "paper towels". This will stop the oil from running down the engine and into the bottom of your generator as you are tipping it over.
5. Quickly, tilt the generator over a drain pan and allow it to empty. There is less than 1/2 a quart of oil in this unit and it will drain fast.
6. Tilt the unit back in a upright position after all the oil has drained.
7. At this point use a funnel to put the proper amount of new oil back into the generator. You will find that Honda list the capacity at 0.42 US quarts or 13.5 US Ounces for the EU2000i Inverter Generator.
8. Once the proper amount of oil has been installed screw the dipstick back into the unit and wipe off all the excess oil off.
9. Install the cover and turn the engine switch and vent to the ON position. Run the generator for a minute and turn off. Remove the cover to and look for any slow discharge or escape of oil. If all appears to be clean and oil free reinstall the cover.
10. Wash your hands with soap and water. You have completed your oil change in 10 easy steps.
Overall, the Honda EU2000i inverter generator is a very easy unit to maintain and will offer years of usage. The cost of time and oil is minimal to the cost of a new generator.
Note: Two oil changes or one quart of improperly disposed of oil will contaminate 250,000 gallons of drinking water: a year's supply for 12.5 people!
