2015 Ibiza Cupra 1.4 Petrol Engine Oil

I'm sure you probably have your answer by now but you need a synthetic 5w -30 oil like castrol edge or Mobil one.

It must meet the correct spec for your engine, not just any 5W-30.

Put you reg. mark into the shell lube match website and it'll list oils suitable, and of course you have oils that exceed the spec and others that only just meet with the spec, as mentioned..
