Hello guys,
Background: my in-laws recently bought an (ugly) Citroën Berlingo, 1,6 HDI 92hp (told them not to, but the price was good apparently).
Was dealer maintain, basically had 3 very pricey OC with cabin filter change. It has around 53000Km.
So, since they are on holiday with us, I changed the fuel and air filter, and the cabin filter (which was apparently "forgotten" by the dealer last time). Also changed the gearbox's oil, which according to Citroën is never needed (it was dark anyway), but it surely improved the feeling of said gearbox.
Now what oil?
I was browsing on the ACEA website, and noticed C4 oils (never really paid attention to "C" oils before). Are these like the best thing since sliced bread for DPF vehicles? What's not to love ? HTHS 3,5 min, very low SAPS, less sulphur and min TBN of 6. It offers the "advantages" of C3 oils with the "benefits" (for the DPF) of C1 oils, with higher HTHS, lower NOACK, more Phosphorus, and a guaranteed starting TBN.
Am I missing something here? On the paper, C4 oils seem superior to C2 or C3, so why aren't more car makers recommending C4 oils? I admit C4 oil selection is pretty limited, but apart from that?
