Why and How Often Does Your Generator Need an Oil Change?

Why are Generator Oil Changes Important?

Time without power is money lost. That’s why you invested in a generator and why you rely on a service provider to take care of your equipment to ensure its proper operation in an emergency. Generators require regular operation along with a routine scheduled maintenance to prevent their engines from seizing or failing during emergencies.

Benefits of Yearly Oil Changes

There’s nothing quite like fresh oil to reach peak engine performance when running your generator during an emergency. Generator engines have a variety of parts that move at high speeds. These moving parts tend to cause friction, which produces heat. If you schedule yearly oil changes with a qualified generator service provider like GenServe, your generator engine will have proper lubrication that reduces the amount of heat produced by the engine. Oil changes also get rid of dirt and debris, which makes your engine run slower. If your generator engine heats up because of old oil, it will wear down and eventually stop working properly or more importantly fail during an emergency or power outage.
