Common Applications
Honda GX engines power thousands of equipment types across Canada:
- Pressure washers — GX160, GX200, and GX390 are the most popular choices for commercial pressure washer builds and replacements. The GX390 powers 4000+ PSI commercial units.

Honda Engine FAQ
What is the most popular Honda engine?
The GX160 (5.5 HP) is Honda's best-selling small engine worldwide, followed closely by the GX200 (6.5 HP). Both are widely used in go-karts, pressure washers, and commercial equipment.
How long do Honda GX engines last?
With proper maintenance (regular oil changes every 50-100 hours, clean air filter, fresh fuel), a Honda GX engine typically lasts 3,000+ hours of commercial use — often 2-3x longer than budget clone alternatives.
Can I replace my old engine with a Honda GX?
In most cases, yes. Honda GX engines use standard mounting patterns. Measure your crankshaft diameter (common: 3/4", 1"), crankshaft length, and mounting bolt pattern. The GX160 and GX200 share mounting dimensions with most clone engines, making them direct bolt-on replacements.
What's the difference between GX and iGX?
The iGX series adds electronic fuel injection (EFI), automatic choke, electronic governor, and self-tuning capability. Benefits: easier starting in cold weather, better fuel economy (up to 15% improvement), consistent performance at any altitude or temperature, and diagnostic capability.
Do Honda engines come with a warranty?
Yes. Honda GX engines carry a 3-year limited warranty for residential use and 1-year for commercial use in Canada.
What oil should I use in my Honda GX engine?
Honda recommends 10W-30 API SG or higher. In very cold weather (below -10°C), use 5W-30. Change oil after the first 20 hours (break-in), then every 100 hours or 6 months.
Why does my Honda engine surge or hunt?
The most common cause is a partially clogged carburetor jet from old fuel. Use fresh fuel with stabilizer, and clean or replace the carburetor. We stock genuine Honda carburetors.
Are Honda clone engines as good?
Clone engines (Predator, Lifan, etc.) copy Honda's design but use lower-grade materials. They cost less upfront but typically last 500-1000 hours vs 3000+ for genuine Honda. For commercial or daily use, genuine Honda pays for itself.
