ABSTRACT
The advancement of combustion engines is driven by stricter emission regulations (e.g., Euro/EPA standards), requiring innovations in lubrication. Modern oils must ensure wear protection, emission system compatibility (e.g., DPFs, SCRs) and fuel efficiency. This paper analyzes updates to ACEA, API, and OEM specifications, focusing on oxidation resistance, low-SAPS formulations, and fuel economy. The trend toward low-viscosity oils (0W-20, 0W-16) reduces friction but challenges lubrication under high loads. The study evaluates these changes’ impact on engine durability and future oil development amid tightening sustainability and emission norms. This article will analize lubricant requirments for passenger cars and light commercial vehicles.
