Very good oil, I have been using it for two years in my golf V gt 1.4 170hp, instead of the golden Castrol ones, recommended to me by the mechanic because they have the same specifications 504-507 as Castrol Edge, they are equally good and more economical. From the first time I used them, I felt the engine working smoothly and linearly, and the revs dropping very smoothly when I release the gas, I don't think I will ever change it with another brand
