A mass fuel inspection across 15 regions of Russia showed that large chain stations mostly comply with the standards, while non-chain gas stations often sell low-class fuel disguised as K5. Even the federal player Teboil was found to have triple the allowed sulfur content.
Otabek YusupovAssociate Professor of Perm Polytech Sergey Pestrikov told Gazeta.Ru that K3 (Euro-3) ecological class gasoline contains up to 150 mg/kg of sulfur versus 10 mg/kg for K5. Sulfur combustion products pollute the air and irritate the airways, especially in people with asthma. Sulfur also reduces the efficiency of the catalytic converter and oxygen sensors, increasing emissions and fuel consumption.
