I recently bought a new 1.2 Suzuki Swift. Only done 2,000 miles but the oil could already do with a top up. The handbook says the number 1 recommended oil is Castrol Magnatec 0w - 20.

My question - is this what I should use to top up in advance of the first service or will the factory fitted oil be different to allow for bedding in etc. In that case what should I use?

The move to 0w - 20 oils seems to be gaining momentum.
