Two-stroke gasoline engines are preferred when mechanical simplicity, light weight, and high [[power-to-weight ratio]] are design priorities. By mixing oil with fuel, they can operate in any orientation as the [[sump|oil reservoir]] does not depend on gravity.
 
A number of mainstream automobile manufacturers have used two-stroke engines in the past, including the Swedish [[Saab Automobile|Saab]], German manufacturers [[DKW]], [[Auto-Union]], [[VEB Sachsenring Automobilwerke Zwickau]], [[VEB Automobilwerk Eisenach]], and [[Simson (company)|VEB Fahrzeug- und Jagdwaffenwerk]], and Polish manufacturers [[Fabryka Samochodów Osobowych|FSO]] and [[Fabryka Samochodów Małolitrażowych|FSM]]. The Japanese manufacturers [[Suzuki]] and [[Subaru]] did the same in the 1970s.<ref>{{cite web|url=http://www.lj10.com/lj50info/ |title=Suzuki LJ50 INFO |publisher=Lj10.com |access-date=2010-11-07}}</ref> Production of two-stroke cars ended in the 1980s in the West, due to increasingly stringent [[Clean Air Act (United States)|regulation of air pollution]].<ref>{{cite web|url=https://www.epa.gov/vehicles-and-engines|title=Vehicles and Engines|first=OAR|last=US EPA|date=16 August 2016|website=US EPA}}</ref> [[Eastern Bloc]] countries continued until around 1991, with the [[Trabant]] and [[Wartburg (marque)|Wartburg]] in East Germany.

Two-stroke engines are still found in a variety of small propulsion applications, such as [[outboard motor]]s, small on- and [[dirt bike|off-road]] [[motorcycle]]s, [[moped]]s, [[scooter (motorcycle)|motor scooter]]s, [[motorized bicycle]]s, [[tuk-tuk]]s, [[snowmobile]]s, [[go-kart]]s, [[radio-controlled car|RC cars]], [[ultralight]] and [[model airplane|model]] airplanes. Particularly in developed countries, pollution regulations have meant that their use for many of these applications is being phased out.

Due to their high power-to-weight ratio and ability to be used in any orientation, two-stroke engines are common in handheld outdoor power tools including [[leaf blower]]s, [[chainsaw]]s, and [[string trimmer]]s.

Two-stroke [[diesel engine]]s are found mostly in large industrial and marine applications, as well as some trucks and heavy machinery.
