Sorry to re-open an old post.
I made a post about which oil to use in my 147 1.9JTDm 16v. After ordering some Selenia WR 5w-40 (ACEA B3) as per the car's manual I ended up with WR Pure Energy 5w-30 which meets the ACEA C2 rating. The supplier told me the oil was a correct substitute because of reasons x y and z etc etc. The reason behind this change from what I can gather is to preserve the DPF, please correct me if I'm wrong. I thought that a DPF was fitted to comply with Euro 4 Emissions regulations which came in around 2009? If so did pre-2009 Alfa's have them fitted? The handbook details DPF's but states that it's relevant only to certain markets.
I could get no definite answer as to whether the 147 has a DPF. My local Alfa dealer couldn't tell me over the phone with a chassis number or VIN. The helpful guys at Alfa Workshop said quite certainly, "It will do." They should know better than most. I also heard that if the engine has a lambda sensor connected below the turbo is does not have a DPF. The exhaust is quite sooty just to make things more uncertain, although I suppose you should expect a small amount in the pipes. I know many of the Alfa 159's had a DPF fitted but other users who have GT's and 147's seem to be unsure.
After all this I'm still asking myself, so does it have DPF or not. Can I use this ACEA C2 oil or is it completely unnecessary because I have no DPF? Has anyone else had experience with this?
