My GTi had its 110K (107,000). mile service carried out at a VAG specialist and this time they put in this oil rather than Castrol 5w40 that I usually have. I am fine with that, but where can I buy top up bottles from (1tr)?
But in the meantime I have 1 and a half bottles of Castrol 1ltr topup oil and I am not sure what to do with it, as I don't really like mixing oil brands (although I did read on here that Quantum and Castrol is the same??).
I usually buy from Opie Oils, but they don't appear to stock Quantum?
Any help/pointing in the right direction would be great
