Most European vehicle manufacturers

Most European vehicle manufacturers are satisfied to specify ACEA quality oils, though some still retain their own approval system. Notable examples are Mercedes Benz who define additional requirements beyond the ACEA limits, VW, Porsche, BMW, Peugeot, Renault and Fiat.
In Japan, vehicle manufacturers market their own brands of oil through their spare parts networks, and these are referred to as “Genuine Oils”. The requirements of those oils are set using in-house engine tests in conjunction with a single Japanese oil manufacturer.
