Abstract

Aditivo de viscosidad propio para conferir un VIE de por lo menos 155 a un aceite lubricante que presenta, antes de la incorporación de dicho aditivo, una viscosidad a 100°C de 4,8 a 5,5 mm²/s y un VIE de 85 a 100, que presenta una resistencia al cizallamiento tal que el descenso relativo de viscosidad después de cuatro horas bajo la prueba 'VKA' o después de veinte horas en la prueba 'FZG' se inferior a 13.
