One way to have your generator last a long time is to change the oil regularly. If you don’t know how to change generator oil, this guide should help. There are two things to consider when thinking of oil change.

The first is to know what brand of generator you own. For instance, the maintenance routine for a Honda EG5000 generator can be different from other brands of generator. It is important that you know the model of generator you use and where to check the oil.

The second factor to consider when changing your generator’s oil is to determine how frequently you use the generator. If you run your generator for long hours or if you run it every once in a while. When you replace the old oil with new oil in your generator, it will help the vital parts of the engine function properly. We will show you how to go about the generator oil change and when to change it.

Oil Checking and How Often The Oil Change Should Be Done

How to Change Generator Oil?If you just bought your generator, either Honda, Generac or other brand, you will need to put in new oil because it is very much likely that the manufacturer did not put oil in the generator. Now, if you have had your generator turned on for a while, you need to turn it off and allow the engine to sit for a while. Give it two minutes for the oil to settle. Then you can use the dipstick from the back of the engine to check the oil. Make sure you wipe it clean with a cloth before you use it to check the oil. You will place the dipstick inside the dipstick tube and pull it out to look at it. This will let you know if the oil needs changing. This shouldn’t be a difficult process if you have a regular maintenance routine for your generator. Experts recommend that you change your generator oil at least every 50 to 200 hours of operation. This is, however, subjective because it depends on if your generator is new, the brand of the generator, and where you place the generator. Your generator may require regular change if it is placed in a dusty environment or where there are contaminants. It will mix with the oil and increase the number of times you will need to change it.
