Hi all. Just bought a used 2013 Jetta for my teenage son. Was freshly serviced and seems really well maintained, but I’m not sure what oil the used car dealer put in... car has 40,000 miles on it. Should I do a preventative oil change and put in the Castrol 0w-40 I have in the garage? Always heard that VWs were hard on oil, but the 2.5 non turbo was kind of an anomaly to that... thought
