A gasoline mechanic only works on gasoline-powered vehicles, not diesel, electric, or hybrid vehicles. A gas mechanic is typically on-duty at most auto repair shops around the world, performing maintenance, engine rebuilding, and tuneups. The gas mechanic is trained in the operation of gasoline-powered engines as well as the typical mechanics of a vehicle, such as brakes, transmissions, and electrical systems. The majority of a vehicle’s mechanical needs can usually be met someone who has been trained as a gas mechanic.
The modern gasoline-fueled vehicle, unlike the carburetor, can be fuel-injected, turbocharged, or even supercharged. Only diesel mechanics had to be trained in fuel-injection and forced-induction systems in the past. Computer ignition timing, variable valve timing, and variable piston or cylinder firing are all used in modern gasoline engines, which expands the knowledge base required of a gas mechanic. To diagnose a vehicle’s problem, most repair shops use specialized engine diagnostic machines. Not only must the gas mechanic be able to repair the vehicle, but he or she must also be able to connect the computer to the vehicle’s diagnostic ports and program the computer to look for a problem.
In today’s global economy, the average gas mechanic must be able to work on all makes and models of vehicles, regardless of origin. Short of bodywork, a gas mechanic should be able to perform nearly any repair required on a vehicle, from oil changes and tuneups to engine overhauls. Because of the time commitment of body repairs, as well as the inherent mess and contamination of the work environment, most mechanics avoid them. Any engine maintenance that may be attempted in the immediate area will be harmed the dust and debris created sanding and painting.
Many younger and inexperienced mechanics do tedious work like exhaust repair, tire repair, and brake service, while more educated and experienced mechanics are usually reserved for more involved work. One of the more involved tasks that an experienced mechanic might undertake is engine component repair and replacement. Whether a gas mechanic works for a new car dealership, a marina, or an independent repair shop, the level of professionalism and knowledge of the vehicle to be repaired are critical to providing high-quality service. Many mechanics attend periodic training to stay abreast of new technology, functions, and features of gasoline-powered vehicles, as technology in the automobile industry advances with nearly every new model year.
