Editing Starting fluid (section)

===Two stroke engines===
Starting fluid is not recommended for regular use with some [[two-stroke engines]] because it does not possess lubricating qualities by itself. [[Two-stroke engine#Lubrication|Lubrication for two-stroke engines]] is achieved using oil that is either mixed into the fuel by the user or injected automatically into the fuel supply; engines requiring premixed fuel that are run solely on starting fluid do not receive an adequate supply of lubrication to their crankcase and cylinder(s). Engines that haven't been run recently are especially vulnerable to damage from oil starvation; starting fluid, a strong solvent, tends to strip residual oil off of cranks and cylinder walls, further reducing lubrication during the period of fuel starvation.
