Hi everyone, I have been enjoying ownership of my Mk5 GTI now for nearly a month and was wondering what is the best recommended oil to put in her. From service records from Inchcape it looks as if Shell Helix Ultra Pro AV-L 0w30 has been being used but is this correct for the car. currently on 128,000 miles with last service done end of February this year and 3000 miles to date. any advice would be greatly appreciated on which oil to go for and how often to change it.
