Introducing Generac’s OHVI® Engine

This is the only engine designed specifically for extended generator use and not for lawn and garden applications. Powering most of Generac’s popular standby and portable generator models, this impressive engine is sure to keep you confident in your generator’s ability to keep your property properly powered.

Generators are often required to run for hours at a time, day after day. Generac’s OHVI engine utilizes the same type of pressurized oil lubrication used to give automobile engines long and trouble-free lives. This means a significantly longer life than competitive engines—an unprecedented three to four times longer. That is the reliability you need for the long run-times emergency backup can require.

The Power Behind the #1 Home Standby Generator

With one of the broadest home generator product lines, Generac has the exact solution for any backup power need you might have. Furthermore, these generators feature some of the easiest installations on the market thanks to their pre-wired solutions, which means you won’t have to worry about extensive installation times. Find out for yourself why Generac generators have earned the accolades from such prestigious organizations as the Good Housekeeping Research Institute.
