A generator is supposed to last as long as you need it to. Hours, days, and even weeks pass. Constant usage may put an engine under a lot of strain if it isn’t constructed to handle it. 

Say hello to the Generac G-Force & OHVI engine lineup. They’ve been designed to endure the rigors of generating electricity, so you can expect extended life and trouble-free operation.

We’ll provide you the opportunity to learn about Generac engines in this post. We wrote this article with the primary topic “Who makes Generac Engines?” in mind. We hope that by reading this, you will learn everything you need to know about Generac Engines.

Who Makes Generac Engines?

Generac Power Systems Inc. designs and manufactures Generac G-FORCE® and OHVI engines at its Eagle & Whitewater, Wisconsin facility. Generac manufactures portable generators and power sources, with Generac’s Whitewater plant producing the engines on-site. They have an unrivaled track record of dependability.

The Generac OHV engines are neither designed or built in the United States. There is contradictory evidence that some engines are provided by Briggs & Stratton and assembled in China, where Briggs & Stratton has a plant.

Is Generac a Chinese Company?

Generac Power Systems, founded in 1959, is an American producer of generators and power equipment. Because the firm has numerous production sites in the United States, its items are manufactured in the United States.

Some Generac, on the other hand, are built-in China yet can run anything. These generators appear to have been manufactured in the same location because they are quite similar yet have different labels. They all have 12-volt lugs and a few additional things in common.

About The Manufacturer

Built-in 1959, Generac Holdings Inc., or Generac, is an American Fortune 1000 company that makes backup power generating devices for the home, light commercial, and industrial sectors. Generac has manufacturing plants in Berlin, Oshkosh, Jefferson, Eagle, and Whitewater, all in Wisconsin.

Generac produces gas, diesel, and bi-fuel engine-driven power generation equipment, as well as modular paralleling systems, automated transfer switches, and tiny engines. Many various distributors supply the company’s goods to the industrial, commercial, and portable generator sectors.

Generac Industrial Power (a rebranding of its industrial products business) was released in December 2009, with new engines, enclosures, ergonomic and cosmetic improvements. This includes a collaboration with Fiat Powertrain Technologies to provide industrial diesel engines to Generac for use in industrial generators. 

Are Generac Engines Any Good?

According to third-party research, the typical standby generator system on the market has dependability of about 98%. This level of generator dependability, according to Generac Power Systems, is unacceptable.

Generac manufactures diesel-powered engines that offer efficient and dependable electricity as a result of this mindset. Using industrial-grade components and air-cooled technology, this engine is made to last with an affordable price range. Because diesel is more dependable, you will have less work and maintenance to do.

Generac’s engine uses the same sort of pressure oil lubrication that gives automotive engines a long and trouble-free life, and it has a life that is three to four times longer than many competitor engines.

Is Generac Owned by Briggs and Stratton?

Generac, one of the industry’s major generator manufacturers, became public in 2010. Generac Holdings, Inc. is the parent company of Generac. Briggs and Stratton, on the other hand, is an engine manufacturer. Between Briggs & Stratton and Generac, there is a long history.

Briggs purchased Generac Portable Products from the Beacon Group, a New York-based investment group, in 2001. It subsequently went on to establish Briggs & Stratton Power Items, which competed with Generac on several products.


How Long Does a Generac Last?

They are designed to last 40 years, according to Generac’s design department. A well-maintained generator may easily provide 25 years of dependable operation.

How long can a Generac generator run nonstop?

On a full tank, Generac’s portable generators should provide around 10 hours of continuous and reliable power delivery, assuming you’ve connected a 50% load. With a 500-gallon propane tank, the Generac generator should operate 24 hours a day for more than a week.

How much does it cost to service a Generac generator?

Annual Maintenance is required for Generac generators. Generac offers a $200 annual service contract that covers the yearly checkups, while some Generac installation specialists offer $170 per checkup choice.

What does a Generac generator’s green, yellow, red light mean?

A green light indicates that your Generac generator is operational. A yellow light indicates that your generator requires maintenance but is still operating normally. 

The red light on the side of a Generac unit indicates that the device won’t run during an outage for whatever reason. It was merely because the device was turned off in your situation, but regardless, it would not have run and was attempting to indicate that.

How often do I need to have my Generac generator serviced?

Maintenance on a portable or standby generator should be done once a year, just like you would on a loan mower or ATV. Changing the oil is the first and most critical maintenance duty. It is recommended that you use SAE 30 oil (most maintenance kits come with two quarts.)

How loud are Generac Engines?

Generators from Generac are extremely quiet. At three meters, they are evaluated at 66 dB on average (about ten feet). That’s the sound of a phone ringing or the air conditioner running.

How can I tell whether the generator is on?

Once a week, the generator performs a self-diagnostic test that lasts around 10 minutes. This test ensures that your Generac generator will be available when you need it.


With over 60 years in the business, Generac has established a reputation for producing high-quality generators. They come in a variety of sizes, from small portable generators to huge commercial backup generators. Next time your house loses power, remember to utilize Generac generators, which are powered by these robust Generac engines!
