So I'm I'm aproaching 5k miles in my 2015 gti and have decided to do my first oil change at 5k. This is my first vw by the way. I have a question about the oil specification numbers in the hand book. Does the oil I need to use match all of the numbers listed in the vehicle manual? The cars oil cap and hoses are marked with Castrol sae 5w-40 so I got that much but the only Castrol oil I can find o nlynlist one of the specification numbers in the manual.
