hi all, as my originally summer use only beast is now a regular winter driver i am looking for feedback and recommendations for a quality winter oil.
i have used BND oil for the last 3 years and i am very pleased with the oil when only used in the summer months. i have had to use the car after being sat outside in minus 20 celcius and its not a pleasant noise as its mineral based and a 7.5w.
i used to use mobil 1 0w40 in my old 2.7t winter car and it suited the car well but i know the RS6 is more piccy on oil type.
im leaning towards amsoil 5w 40 european spec but any suggestions would be helpfull and appreciated.
