Unleaded 95

The enhancing additives of our EuroSuper 95 gasoline ensure that inlet valves and combustion chambers are kept clean, reduce corrosion, improve performance and lower fuel consumption.

While out on a trip, it's worth buying EuroSuper 95 at an ORLEN fuel station. Simply pull over at any of our 2,000 stations in Poland and experience highest quality driving.

Characteristics of 95 unleaded gasoline

ORLEN’s unleaded gasoline with a research octane number 95 is sold under the name of EuroSuper 95. The product has been enriched with premium quality refining, detergent, anticorrosive and antioxidant additives. The detergent facilitates keeping the engine intake system clean, and reduces formation of deposits on intake valves and in the combustion chamber (as confirmed in bench tests in the Mercedes Benz M102E engine – the CEC F-05-93 Inlet Valve Cleanliness in the MB M102E Engine method). The corrosion inhibitor protects the engine and fuel system from corrosion. Based on the results of a special research test, the additives used in the product significantly reduce fuel consumption and deposit formation, while also mitigating the risk of damage and protecting the engine. 

The EuroSuper 95 gasoline makes it possible to unleash the full power of a car, ensuring smooth operation of the engine, which contributes to reduced fuel consumption. The antioxidant additives prevent gasoline ageing, improve its stability, and inhibit deterioration of its properties while in storage (such deterioration manifests itself through fuel darkening, as well as build-up of resins and deposits).

In addition, the unleaded EuroSuper 95 gasoline ensures that the engine works properly even under heavy load, at both low and high temperatures. The use of EuroSuper 95 gasoline extends oil change intervals, thus reducing oil consumption. It also improves the lifespan of spark plugs and the exhaust system. The EuroSuper 95 gasoline protects the catalyst system and prolongs its useful life, as well as reduces hydrocarbon emissions into the air.

The gasoline does not contain manganese-based metallic additives, including methylcyclopentadienyl manganese tricarbonyl (MMT).

Unleaded 95 – Application

The fuel is intended for spark ignition gasoline engines capable of operating on unleaded gasoline.
