Ultimate-Performance Multigrade Diesel Engine Oil for Modern Low-Emission Engines with Outstanding Soot Control, Exceeding API Service CJ-4 and ACEA E9 Performance Levels
PETRONAS Urania Supremo CJ-4 is an environmentally friendly ultimate-performance multigrade diesel engine oil for used in the most severe on-highway and off-highway applications. It is specially engineered for modern, high-output, low-emission engines including those fitted with exhaust after-treatment system using Diesel Particulate Filter (DPF), Selective Catalyst Regeneration (SCR), Diesel Oxidation Catalyst (DOC) and Exhaust Gas Recirculation (EGR).
It delivers exceptional performance for the latest EPA 2007 and Euro V compliance engines as well as older high speed turbocharged or naturally aspirated engines running on ultra low sulphur or high sulphur diesel fuel.
Specially formulated with unconventional base fluids technology and advanced low-ash additive system to ensure excellent control over soot induced wear, high temperature piston deposits, corrosion, foaming and oxidation stability. It also provides excellent resistance to bore polishing, a high level of wear protection and ensures superior engine cleanliness at extended drain intervals.
