El mejor aceite para nuestro ix55

[daniel55]

Hasta el dia de hoy pongo en mis automóviles el aceite REPSOL LONG LIFE 0W-30 de 100-115 € los 5 l. por no encontrar donde comprar los que me interesan, que son:
1º .- Mobil Delvac 1 ESP CJ-4 Synthetic 5W-40 aceite totalmente sintético de rendimiento supremo para motores diesel
2º .- Mobil Delvac 1 5W-40 CI-4 es un aceite totalmente sintético de rendimiento supremo para motores diesel
¿ Alguien puede indicarme donde conseguirlo ?

Os dejo una prueba realizada con un porche 928 S4 en un laboratorio alemán.
saludos, Daniel
