Bensiinis

Bensiinis is the Estonian term for gasoline, a refined petroleum product used primarily as fuel for spark-ignition engines in cars, motorcycles, and some small machinery. It is a complex blend of hydrocarbons with varying chain lengths, formulated to deliver a high energy content while achieving reliable ignition. Gasoline formulations differ by market, but they are designed to provide suitable volatility, efficiency, and cold-start performance. In many places, octane ratings are used to indicate performance, with figures such as 95 or 98 RON, and, in some markets, an Anti-Knock Index that combines research and motor octane tests.

Gasoline is produced through refining crude oil. The refining process includes distillation to separate fractions, followed by treatments such as catalytic cracking, reforming, and blending of hydrocarbon streams. Additives are included to improve engine cleanliness, prevent corrosion, and control emissions; these can include detergents, antioxidants, and anti-oxidation agents. In some regions, ethanol or other bio-blends are mixed with gasoline to reduce carbon footprint and meet regulatory requirements. Benzene content is regulated in many jurisdictions due to health concerns.

Uses and safety: gasoline is the primary fuel for light motor vehicles and various small engines. It is highly flammable and emits vapors that can form explosive mixtures with air. Proper storage in approved containers, away from heat sources, and adherence to handling guidelines are essential. Exposure to gasoline vapors can affect health, with particular concern for prolonged inhalation and skin contact. Environmental concerns include soil and groundwater contamination from spills and evaporation contributing to air pollution.

Regulation and market: gasoline is subject to standards that regulate octane, sulfur content, vapor pressure, and detergency. Standards vary by country and region, reflecting local environmental and safety policies.
