Hi.
My handbook states the oil has to be to C3 spec. From what I have read this oil is for use in engines with a DPF and or a 3 way cat. I would suspect that if the engine uses oil it will be less damaging to DPF's and Cat's. The 1.2 is a well proven engine and has never been known as an oil burner......I do wonder though it is down to the use of fully synthetic oil during the bedding in stage, a semi synthetic oil would no doubt be better. Thing is no manufacturer wants to have the cost these days of a first service. So surely at 18,000 even on fully synthetic the rings will be bedded in and the C3 spec may be a bit of an overkill.
Being an old engine why do we need to adhere to this spec?
