Gas mechanics work on gasoline-powered vehicles, performing maintenance, engine rebuilds, and adjustments. They must be knowledgeable in fuel injection, forced induction systems, and computer diagnostics. Gas mechanics must work on all makes of vehicles and attend periodic training to stay up to date with new technologies.
A gas mechanic works exclusively with gasoline-powered vehicles, not diesel, electric, or hybrid. Typically performing maintenance, engine rebuilds and adjustments, a gas mechanic is usually on duty in most auto repair shops across the world. Educated in the operational aspects of the gasoline engine, the gas mechanic is also trained in typical common vehicle mechanics such as brakes, transmissions and electrical systems. The average mechanical needs of a vehicle owner can usually be met by someone trained as a gas mechanic.
Unlike the carburetor, the modern vehicle powered by gasoline can be injected, turbocharged or even supercharged. In the past, only diesel mechanics needed to be trained in fuel injection and forced induction systems. The modern gasoline engine uses computer ignition timing, variable valve timing, and variable piston or cylinder actuation, expanding the knowledge base needed to be a gas mechanic. Most repair shops use specific engine diagnostic machines to identify a problem with a vehicle. The gas mechanic must be able to not only repair the vehicle, but also connect the computer to the vehicle’s diagnostic ports and program the computer to look for a problem.
With a global and worldwide economy, the average gas mechanic must be able to work on all makes of vehicles, regardless of country of origin. From oil changes and tune-ups to engine overhauls, a gas mechanic should be able to complete almost any repair needed on a vehicle with a lack of bodywork. Most mechanics do not perform body repairs due to the time intensity of the repair, as well as the basic mess and contamination of the work area. The dust and debris caused by sanding and painting is detrimental to any engine maintenance that may be attempted in the direct area.
Many younger, less experienced mechanics carry out tedious jobs such as muffler repair, tire repair and brake service, while more educated and experienced mechanics are typically reserved for more involved jobs. Repairing and replacing engine components is one of the most involved tasks that can be performed by an experienced mechanic. Whether the gas mechanic works for a new vehicle dealership, a marina or an independent repair facility, the level of professionalism and knowledge of the vehicle being repaired equates to providing quality of service. With technology in the auto industry advancing with each model year, many mechanics attend periodic training to stay abreast of new technologies, functions and features in gasoline-powered vehicles.
