ग्यास टर्बाइन इन्जिनको फाइदा तथा बेफाइदा निम्नानुसार छन्:<ref>{{cite web|last=Brain |first=Marshall |url= http://science.howstuffworks.com/turbine2.htm |title=How Gas Turbine Engines Work |publisher=Science.howstuffworks.com |date=1 April 2000 |access-date=13 March 2016}}</ref>
* Very high [[power-to-weight ratio]] compared to reciprocating engines.
* Smaller than most reciprocating engines of the same power rating.
* Smooth rotation of the main shaft produces far less vibration than a reciprocating engine.
* Fewer moving parts than reciprocating engines results in lower maintenance cost and higher reliability/availability over its service life.
* Greater reliability, particularly in applications where sustained high power output is required.
* Waste heat is dissipated almost entirely in the exhaust. This results in a high-temperature exhaust stream that is very usable for boiling water in a [[combined cycle]], or for [[cogeneration]].
* Lower peak combustion pressures than reciprocating engines in general.
* High shaft speeds in smaller "free turbine units", although larger gas turbines employed in power generation operate at synchronous speeds.
* Low lubricating oil cost and consumption.
* Can run on a wide variety of fuels.
* Very low toxic emissions of CO and HC due to excess air, complete combustion and no "quench" of the flame on cold surfaces.
* Core engine costs can be high due to use of exotic materials.
* Less efficient than reciprocating engines at idle speed.
* Longer startup than reciprocating engines.
* Less responsive to changes in power demand compared with reciprocating engines.
* Characteristic whine can be hard to suppress.
