About Gas & Diesel Engine Equipment Guide
Gas & Diesel Engine Equipment Guide is an independent, reader-supported publication about engine-powered equipment: generators, gasoline and diesel engines, water pumps, air compressors, pressure washers and the tools of a working garage. We write for people who have to choose a piece of equipment, keep it running, or work out why it has stopped.

How we work
Our guides are researched from manufacturer documentation, owner’s manuals, published specifications and official safety guidance from bodies such as the U.S. Consumer Product Safety Commission. We do not claim hands-on testing unless an article says so explicitly, and we do not invent specifications, prices, ratings or experience. When a recommendation is our own editorial judgment, we say so. Our editorial standards page describes the process in detail, including how we handle corrections.
How the site is funded
Some links on this site go to Amazon. As an Amazon Associate we earn from qualifying purchases, at no extra cost to you. Affiliate links never decide what we recommend, and we link to search results for a class of equipment rather than pushing a single product. Our affiliate disclosure explains this fully. The site carries no sponsored content and no display advertising.
A note on safety
Engines, fuel, electricity and pressurized air can injure and kill. Our articles include the safety steps that manufacturers and safety agencies recommend, but they are general guidance, not a substitute for the manual that came with your equipment or for a licensed professional. Please read our equipment safety notice.
