PETRONAS Urania 800 15W-40 is formulated with ViscGuard™ to effectively guard against engine silent killers (engine deposits: soots, ash, deposits and varnish), preventing abrasive wear and oxidation to maintain optimal oil viscosity. This helps in extending engine life and reduces the total cost of ownership. It is suitable for heavy duty diesel applications including turbocharged and naturally aspirated diesel engines, both on-highway and off-highway, running on high or ultra-low sulphur diesel.
