What makes the Honda iGX800 different from a standard GX engine?

The iGX800 features Honda’s advanced Electronic Fuel Injection (EFI) system along with an integrated ECU, STR Self-Tuning Regulator governor, and Drive-by-Wire controls for improved fuel efficiency, automatic RPM management, smoother operation, and intelligent engine diagnostics.

Why is EFI beneficial on a pressure washer system?

Electronic Fuel Injection helps maintain consistent engine performance under varying load conditions while improving fuel efficiency, throttle response, cold-weather starting, and overall operational stability.

What is the STR Governor System?

Honda’s STR (Self-Tuning Regulator) governor system automatically adjusts engine output and RPM based on load demand to help maintain stable performance during operation.

What oil does the Honda iGX800 use?

Honda recommends SAE 10W-30 engine oil for general operation across most temperature ranges.
