Thermal　enhancement　of　engine　oil　plays　an　important　role　in　a　variety　of　industrial　applications　including　heat　exchangers,　automotive　cooling　systems,　renewable　energy　systems,　biomedical　devices,　and　advanced　manufacturing　processes.　Considering　the　high　demand　in　industry,　present　investigation　explores　thermal　optimization　of　engine　oil　contained　in　a　porous　inclined　cavity　involving　dispersion　of　hybrid　nanoparticles　along　with　inclusion　of　micropolar　fluid　flow　phenomena.　Numerical　analysis　is　performed　on　the　micropolar　nanofluid　containing　iron　oxide　and　molybdenum　disulfide　while　considering　the　effect　of　thermal　radiation,　buoyancy　force,　viscous　dissipation,　magnetic　field＇s　strength,　porosity,　and　vortex　viscosity.　Numerical　solutions　of　the　dimensionless　governing　equations　are　provided　through　utilization　of　FVM.　The　coupling　of　velocity　and　pressure　terms　was　achieved　through　implementation　of　SIMPLE　algorithm.　The　results　are　illustrated　through　streamlines,　contours,　velocity,　temperature　profiles　and　heat　flux.　The　outcomes　revealed　that　an　augment　in　Hartmann　number　and　thermal　radiation　parameter　results　in　higher　heat　flux　rate.　The　incrementation　in　Hartmann　number　disrupted　the　flow　resulting　a　reduction　in　the　size　of　major　vortices　and　similar　trend　is　noted　in　case　of　temperature　profile　for　the　said　parameters.　The　outcomes　complement　the　continuing　efforts　to　improve　the　thermal　management　of　various　applications　and　offer　insightful　information　for　optimizing　engine　oil　compositions.
