LUKOIL AVANTGARDE ULTRA API CI-4/SL 15W-40 are premium all-season oils for heavily loaded diesel engines, including those equipped with turbocharging, operating under particularly severe operating conditions and with extended service intervals. These oils are designed for modern diesel engines of the latest generation that meet the emission requirements of both the previously issued Euro-1, Euro-2, Euro-3, and the most modern Euro-4 (without diesel particulate filters (DPF)).

LUKOIL AVANTGARDE ULTRA API CI-4/SL 15W-40 oils are produced on the basis of modern synthetic and highly refined mineral base oils with the use of a highly effective carefully balanced package of foreign-made additives. LUKOIL AVANTGARDE ULTRA API CI-4/SL semi-synthetic oils of SAE 15W-40 viscosity grade are distinguished by improved low-temperature properties and make it easier to start the engine at low temperatures.
