According to a report by The Moscow Times, the Russian Ministry of Energy’s press service announced that the country will permit the production, importation, and sale of K2, K3, and K4 ecological class automotive gasoline complying with Euro-2, Euro-3, and Euro-4 standards until July 1, 2027. Most nations globally have banned these older fuel grades. The ministry stressed that this decision is temporary, designed to secure stable domestic fuel market supplies and prevent potential shortages as an anti-crisis measure.
Temporary Fuel Standards and Environmental Rollback
The ministry stated that the policy change aims to maintain a balance between fuel quality requirements and the necessity of ensuring availability for consumers. Unlike the current Euro-5 standard introduced in Russia in 2016, Euro-2 gasoline permits up to 500 mg/kg of sulfur. By comparison, Euro-5 fuel caps sulfur at just 10 mg/kg. Furthermore, the Euro-2 standard does not regulate aromatic hydrocarbons, including benzene. It also permits monomethylaniline (MMA), an octane-boosting additive. Most countries banned MMA due to high toxicity and potential carcinogenic risks, though Russia utilized it until 2016.

Modern Engine Compatibility and Mechanical Risks
Modern engines are not built to handle lower-grade fuel formulations safely. Fuel market expert Anastasija Bunina notes that increased sulfur content accelerates the wear of cylinder and piston groups, fuel systems, engine oil, spark plugs, valves, injectors, and catalytic converters. Earlier in July, the Russian government permitted select domestic oil refineries to produce and sell Euro-3 standard gasoline containing up to 150 mg/kg of sulfur through the end of the year. However, those earlier concessions apparently proved insufficient to supply the domestic market fully.
Frequently Asked Questions
Why did the Russian Ministry of Energy lower fuel standards?
According to The Moscow Times, the ministry enacted the measure temporarily to secure stable domestic market supplies and prevent potential fuel shortages.
What are the key differences between Euro-2 and Euro-5 gasoline?
Euro-2 gasoline allows up to 500 mg/kg of sulfur and permits monomethylaniline (MMA) additives without regulating aromatic hydrocarbons. Euro-5 limits sulfur to 10 mg/kg and bans toxic additives like MMA.
How do lower fuel standards affect modern vehicles?
Fuel market expert Anastasija Bunina states that modern engines are unsuited for this fuel, noting that higher sulfur content accelerates wear on pistons, fuel systems, spark plugs, valves, and catalytic converters.
