But what if you find yourself without it? Well, there are many items that you can use to substitute for starting fluid if you desperately need to get your car running. This is where starting fluid comes in to save the day. It can be due to many things but is commonly caused by the inability of gas to ignite. The effects of inhalation vary, but have been known to include lightheadedness, loss of coordination, paranoia, and sometimes hallucinations.An engine that won’t start has to be driver’s worst nightmares. This trend has gradually picked up since the turn of the century, as phrases such as 'etherized' and 'ethervision' have gained popularity. Sometimes referred to as 'passing the shirt,' the starting fluid is sprayed on a piece of cloth and held up to one's face for inhalation. Use at the present time directly as an inhalant includes the effect of the petroleum solvents, which are more toxic as inhalants than diethyl ether. WD-40 was previously recommended for use on two stroke engines because it has lubricating qualities, but the formulation with non-flammable CO 2 as propellant instead of propane no longer has the same combustible nature, making it useless as starting fluid on any type of engine.ĭiethyl ether has a long history as a medical anesthetic when starting fluid was mostly ether, a similar effect could be obtained using it. 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. 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). Starting fluid is not recommended for regular use with some two-stroke engines because it does not possess lubricating qualities by itself. Caution is required when using starting fluid with diesel engines that have preheat systems in the intake or glow-plugs installed, as the starting fluid may pre-ignite, leading to engine damage. It is used more often with carbureted engines than with fuel injection systems. Mechanics sometimes use it to diagnose starting problems by determining whether the spark and ignition system of the vehicle is functioning if the spark is adequate but the fuel delivery system is not, the engine will run until the starting fluid vapors are consumed. Other uses include cold weather starting, vehicles that run out of fuel and thus require extra time to restore fuel pressure, and sometimes with flooded engines. Using starting fluid to get the engine running faster avoids wear to starters and fatigue to one's arm with pull start engines, especially on rarely used machines. Starting fluid is sprayed into the engine intake near the air filter, or into the carburetor bore or a spark plug hole of an engine to get added fuel to the combustion cylinder quickly. ĭiethyl ether is distinct from petroleum ether (a crude oil distillate consisting mostly of pentane and other alkanes) which has also been used for starting engines. Historically, Diethyl ether, with a small amount of oil, a trace amount of a stabilizer and a hydrocarbon propellant has been used to help start internal combustion engines because of its low 160 ☌ (320 ☏) autoignition temperature. Some formulations contain butane or propane as both propellant and starting fuel. Some modern starting fluid products contain mostly volatile hydrocarbons such as heptane, (the main component of natural gasoline) with a small portion of diethyl ether, and carbon dioxide (as a propellant). It is typically available in an aerosol spray can, and may sometimes be used for starting direct injected diesel engines or lean burn spark engines running on alcohol fuel. Starting fluid is a volatile, flammable liquid which is used to aid the starting of internal combustion engines, especially during cold weather or in engines that are difficult to start using conventional starting procedures.
