Full title and description

GOST R 51866-2002 — "Топлива моторные. Бензин неэтилированный. Технические условия" (English: Automotive fuels. Unleaded petrol. Specifications). The standard defines technical requirements and specification text for unleaded automotive gasoline supplied to the Russian and export markets.

Abstract

This national standard establishes grades, quality limits (octane numbers, volatility, distillation characteristics, sulphur and oxygenate limits, absence of lead and metallic additives), and test/acceptance provisions for unleaded petrol (commonly published as Regular Euro‑92, Premium Euro‑95 and Super Euro‑98). It is aligned with the European EN 228 family of standards and was developed by the Russian technical committee for petroleum fuels and lubricants.

Scope

Applies to unleaded motor gasoline intended for use in petrol‑engine road vehicles designed to run on unleaded petrol; covers products supplied to the Russian domestic and export markets. The standard sets product grades (examples: Регуляр Евро‑92, Премиум Евро‑95, Супер Евро‑98), limits on composition and properties, and references to test methods.

Key topics and requirements

• Definition of product scope and grade names (Regular, Premium, Super — Euro classifications).
• Minimum and maximum octane ratings (research and motor methods) and classification by octane.
• Volatility and distillation requirements (initial boiling/vapour pressure/distillation curve limits).
• Limits on sulphur and other contaminants; prohibition on leaded and metal‑containing additives.
• Requirements for oxygenates/ethanol content and related labelling/test provisions (in line with EN 228 principles).
• Sampling, testing and conformity assessment rules referencing established test methods.

Typical use and users

Used by fuel producers, refiners, distributors, fuel retailers, vehicle fleet operators, testing laboratories, certification bodies and procurement specialists who need to specify, supply, test or certify unleaded gasoline to meet Russian market and export requirements. Automotive engineers and regulatory authorities refer to the standard when assessing fuel compatibility with vehicle emissions and engine requirements.

Related standards

Mainly aligned with the European standard EN 228 series ("Automotive fuels — Unleaded petrol — Requirements and test methods"); other national and regional fuel and fuel‑testing standards (subsequent EN revisions and related GOSTs for fuel testing and diesel specifications) are commonly referenced alongside GOST R 51866‑2002 in regulatory and certification contexts.
