How To Change the Oil On A Portable Generac Generator?

You can change the oil for your portable generac generator with these easy steps. First, you’re going to want to shut off your generator and unplug it from its power supply. Check your owner’s manual if you are unsure of how to do this. Some models may require that you remove the fuel tank to access the oil drain plug.

After you have the generator powered off and unplugged, position your drain pan beneath the oil drain plug. Use a wrench to loosen the oil drain plug, being careful not to burn yourself on any hot oil. Let all of the oil in your generator’s engine run out into your container to avoid spilling it around the outside of your generator.

When all of the old oil has drained, replace the washer on your drain plug and tighten it back up. Refill your generator with new motor oil through its fill port located near where you just drained the old oil from. Be sure that you are putting exactly as much new motor as you took out when draining. Refer to your owner’s manual for specific information about how much oil your generator needs.

If you’re not sure how much oil to put in, the general rule of thumb is that you should add a bit more than a single quart. Be careful not to overfill your generator, as this can cause problems later on. After filling it with new oil, start up your generator and allow it to run for five minutes before shutting it back down.

Check underneath where you drained the old oil from again and make sure there is no evidence of leakage. If everything looks good, then you can go ahead and use your portable generac generator!.

Oil Checking and How Often The Oil Change Should Be Done?

Now when it comes to how often should i check my oil on a portable generac generator. I will say that there is no right and wrong answer for this question, but rather whatever works best for you and your needs. If you use your portable generator frequently, then changing the oil before it gets too dirty maybe your best option.

You can check your oil after a few hours of use, once the generator has cooled down. However, you may also want to check your oil before each use if you do not frequently fire up this piece of machinery.

Whenever you decide to change the oil on your generator, be sure to check it for a few reasons. If the oil is dark or has a burnt smell to it, then chances are that there is a problem with your machine. Sometimes bits of metal from parts rubbing together can contaminate the oil and cause it to turn black.

In this case, you should check your entire generator for any metal bits that may be the cause of the problem. If there is no visible evidence, then you can try changing your oil to see if it helps with the issue.

What Type of Oil for Generator?

The best type of oil to use in a portable generator is a 10W-30 Oil with a viscosity grade of 40. Why! Because it can handle both hot and cold weather conditions, it’s thinner so it flows more easily so the engine gets less wear and tear, etc. So if you want a thicker oil, I would go for one between SAE 30 or SAE 40 weight oils.

What do You Need to Change Your Oil in a Generator?

In general, most people recommend changing your oil every 50 hours on average. However, this depends on the size of the generator that you have as well as how often you use it. Some generators can last longer while others may need changes after several uses but never be afraid to check the oil levels and change it every 25 hours if you need to.

Of course, to lubricate your generator with new oil, you’ll need some of that stuff too. For this project, I recommend getting 5W-30 Oil. This is because it’s thin enough so it won’t cause any trouble but also thick enough for your generator.

You can get away with using 10W-30 or even 5W-20 although they may not break down the carbon deposits as easily (and thus will require more frequent changes). Some folks like Mobil 1 synthetic but I buy my liquids at Walmart for cheap when I find them on sale.


So if your generator is new or you want to keep it clean and running smoothly, then change the oil at least every 25 hours. If you neglect this, then your portable generac generator will be sure to give you problems down the road and probably won’t start up for long periods. Furthermore, if any visible metal bits get into your oil, then we will recommend changing it more frequently until they stop appearing in there.


Q 1) What are the signs of low oil?

A low oil warning light on your generator will go off soon after you see some dark spots on the dipstick. However, if there’s no warning light, then you may notice that it starts to run roughly or dies quickly when in use. You can also check for metal bits in the oil and if they’re present, then chances are your oil is contaminated and should be changed asap!

Q 2) When should i change my portable generac generator’s oil?

The best time to change your portable generac generator’s oil is whenever it’s due for a checkup under normal conditions. I recommend every 25 hours of use but this could vary depending on how often you fire up this machinery. If you don’t use your portable generac generator regularly, then consider changing it more often as carbon buildups will eventually take their toll at some point.

Q 3) What should i look for when checking my oil level?

The first thing to do is pull out the dipstick and wipe it all over with a clean cloth or towel so that it’s clean and dry before putting it back in. Then, pull the stick out and take a look at the color and smell of the liquid on there.

If it’s black or smells burnt then we recommend changing your whole machine as well as looking for any metal bits that may be causing the issue. However, if everything looks normal, then chances are your oil is still good but if you want to be safe, change it anyways.
