Oscar Jade Optimum 5W30 C2 C3 is a very high performance, fully synthetic MID SAPS lubricant for gasoline and diesel engines, including the ones complying with ACEA C2/C3 standard. Oscar Jade Optimum is formulated to reduce pollutant emissions, such as HC, NOx, CO and particles and to protect and ensure longevity of post treatment anti-pollution systems, such as particulate filters (GPF, DPF) and three-way catalysts. Oscar Jade Optimum also helps to lengthen the engine life thanks to its excellent resistance to temperature variations and permits an extra long oil change interval.
