My 2018 GTI performance has done 7k miles, the oil dipstick is showing midway between max and min, so I thought I'd better top up before first service.
I called the local VW service dept for advice as to grade- was told 0w30. He sounded uncertain, so I called another dealer- he told me "10w 40 semi, shell or castrol". Called a third dealer who said "5w30 semi, castrol edge"
So 3 calls, 3 different grades advised!
Now I'm absolutely sure the engine won't explode if I add a litre of slightly different oil, but it would be nice to get consistent advice. Even nicer to get accurate advice, but I have no confidence in these chaps to give that!
Just done the oil change on my old Peugeot and have several litres of Shell Helix 10w40 semi that I bought in bulk from Opieoils. I could put a litre of this in. Should I?
Can anyone advise as to what the recommended grade of oil is?
