How to Change the Oil in Your Westinghouse Generator
Why Regular Oil Changes Matter
Oil keeps your Westinghouse generator running smoothly. Over time, oil breaks down and gets dirty from heat and use. When oil degrades, it can't protect your engine as well, which leads to wear and tear on important parts. Changing the oil regularly helps your generator last longer, work better, and run more reliably when you need it most.
Most Westinghouse generators need an oil change every 50 to 100 hours of use. If you don't run your generator often, change the oil at least once a year before storing it for long periods. Checking your owner's manual will tell you the exact schedule for your specific model. Regular maintenance is one of the easiest ways to keep your generator in good working condition.
What You'll Need
Before you start, gather all the items you'll need. Having everything ready makes the job go faster and smoother. Here's what to collect:
- New oil (check your manual for the right type and amount—usually SAE 10W-30 or similar)
- An oil drain pan (to catch old oil)
- A wrench or socket set (to remove the drain plug)
- An oil filter wrench (if your model has a filter)
- Clean rags or paper towels
- A funnel (to pour new oil without spilling)
- Safety glasses (to protect your eyes)
- Work gloves (optional, but helpful)
You can find most of these items at hardware stores, auto parts shops, or online. The oil type matters—using the wrong oil can damage your engine. Always check your Westinghouse generator's manual to find out exactly which oil to buy and how much you need.
Prepare Your Generator
Safety comes first when working on your generator. Start by letting your generator cool down for at least 5 to 10 minutes after running it. Hot oil can burn your skin, and hot engine parts can cause injuries. Never work on a hot generator. Make sure the generator is turned off and unplugged from any electrical outlets or devices.
Move your generator to a flat, level surface where you have room to work. Place your drain pan underneath where the oil drain plug is located—usually on the bottom of the engine. Put down newspaper or cardboard to protect the ground from any spills. Wear your safety glasses before you begin, and keep paper towels nearby to wipe your hands and clean up drips as you work.
Drain the Old Oil
Locate the oil drain plug on the bottom or lower side of your generator's engine. It's usually a bolt or plug that sticks out slightly. Use your wrench to loosen it by turning it counterclockwise. You don't need to remove it completely yet—just loosen it enough that you can finish unscrewing it by hand.
Once it's loose enough, carefully unscrew the drain plug the rest of the way by hand. Be careful—old oil may still be warm. Let all the old oil drain into the pan below. This may take several minutes, so be patient and let it drain completely. After the oil stops dripping, wipe the drain plug clean with a rag or paper towel. Check that the rubber seal or washer on the plug looks good. If it's cracked or damaged, you may need a new plug.
Replace the Oil Filter (If Equipped)
Not all Westinghouse generators have oil filters, but many do. Check your manual or look at your engine to see if yours has one. If it does, you'll find it on the side or top of the engine. It looks like a small metal cylinder. Use an oil filter wrench to turn it counterclockwise until it comes loose. Then unscrew it by hand the rest of the way and set it aside in your drain pan.
Before installing the new filter, apply a thin layer of new oil around the rubber ring on the top of the filter. This helps create a good seal. Screw the new filter onto the engine by hand only—don't use the wrench. Turn it until the rubber ring just touches the engine, then turn it about three-quarters of one more full turn. This is tight enough. If you over-tighten it, it will be hard to remove next time and may leak.
Add New Oil
Put the drain plug back into the hole on the bottom of the engine and tighten it with your wrench. Tighten it firmly, but don't over-tighten it or you may strip the threads. Place your funnel in the oil fill hole on top of the engine. This hole usually has a cap that twists off. Pour in the new oil slowly and carefully to avoid splashing.
Check your owner's manual to see exactly how much oil your generator needs—this varies by model. After you've added oil, wait about a minute for it to settle. Then check the oil level using the dipstick. Most generators have a dipstick that you pull out, wipe clean, reinsert, and pull out again to read the level. Add more oil a little at a time until the level reaches the "full" mark on the dipstick. Don't overfill it, as this can cause problems.
Check Your Work
Wipe up any spilled oil around the engine with clean rags or paper towels. Make sure the drain plug is tight and the oil filter is secure. Start your generator and let it run for a minute or two at a low speed. This circulates the new oil through the engine. Turn off the generator and let it cool for a few minutes.
After it cools, check the oil level one more time with the dipstick to make sure it's still at the right level. The oil level may drop slightly as it circulates, and that's normal. If it's below the full mark, add a little more. Once everything looks good, you're done with the oil change. Dispose of your old oil properly at a recycling center, auto parts store, or hazardous waste facility—never pour it down the drain or into the ground, as it harms the environment.
Keep Track of Maintenance
Write down the date and the number of hours on your generator when you changed the oil. You can keep this information in your owner's manual, a notebook, or on your phone. This record helps you remember when the next oil change is due. Keeping your generator well-maintained means it will be ready and reliable whenever you need to use it.
Consider setting a reminder on your calendar or phone for your next scheduled oil change. Regular maintenance doesn't take much time, but it makes a big difference in how long your generator lasts and how well it performs. A well-maintained generator is a dependable generator.

Frequently Asked Questions
How often should I change the oil in my Westinghouse generator?
Most Westinghouse generators need an oil change every 50 to 100 hours of use. If you use your generator regularly, you may need to change the oil more often. If you don't use it much, change it at least once a year before storing it for the winter or for long periods. Your owner's manual will have the exact recommendation for your specific model. Keeping track of your hours helps you stay on schedule.
What type of oil should I use in my Westinghouse generator?
Always check your Westinghouse generator's owner's manual to find out the correct oil type for your model. Most generators use SAE 10W-30 or SAE 5W-30 oil, but some models may require different grades. Using the wrong oil can reduce engine performance and cause damage. The manual will also tell you how much oil your generator needs. When you buy oil, bring your manual to the store so you can get the right product.
Can I change my generator's oil without an oil filter wrench?
If your Westinghouse generator has an oil filter and you don't have an oil filter wrench, you have a few options. You can wrap a rubber band or old cloth around the filter to help you grip it better and turn it by hand. Some people use a strap wrench or even a piece of old rubber from a bicycle tire. However, an oil filter wrench is inexpensive and makes the job much easier. You can buy one at any auto parts store or online. If the filter is stuck very tight, you may need the proper wrench to remove it without damaging it.
What should I do with the old oil after I drain it?
Never pour old oil down the drain, into the ground, or in the trash. Old oil harms the environment and is illegal to dispose of that way in most places. Instead, take your old oil to a recycling center, auto parts store, or hazardous waste facility. Many auto parts stores will take used oil for free or for a small fee. Some communities have special collection days for hazardous waste. Call your local waste management office to find out where you can drop off oil in your area.
