Dads new Leon FR 2.0TDi needs a top up of oil.
Now I have 2 types in my garage and just wondering which I should use for the top up
1. Special Plus Advanced Engine Oil from Audi 505 01 (This is in my Ibiza FR)
or
2. Castrol SLX Longlife II 506 01 also from Audi
I know 2. is for Longlife servicing, but is this ok to use for a top up?
