“I bought my Seat Leon FR new in 2009. After the first 3 services with the main dealer, I have had it serviced every year in the same garage specializing in VW, Audi, Seat and Skoda. I have always provided my own Oil, (Mobil 1 ESP 5w-30 Advanced Fully Synthetic). The car is fifteen years old in September and the engine runs like new, never needing a top up between services. I believe this speaks volumes for the quality of this oil.”
