Wrong oil TDCi

[jtraf]

Well have just joined the forum and I have a question to ask.

Lasts week I bought a 2010 TDCi focus to use as a fuel efficient means of getting to and from work which is an 80kay round trip. So yesterday I went down to the local SCA and had a look in there oil book for what the right oil is for the new toy. They had a book the lists all makes and models of all the oils they sell in it. Now it listed Shell Helix Ultra 5W-40 as a suitable oil for the motor. I have used this oil in my past cars and always found it to be a great product. As I plan to keep this one for a while I decided to keep the trend going.

Now I changed the oil and filter and drove home yesterday. Now on searching the web last night I found a few threads about oils and on further investigation found out that the Shell Helix I bought yesterday is not suitable for the engine as it a motor fitted with a Particle filter.

My question is will it damage the engine having this oil in it for say 5000 Kay's or should I drop it immediately? If I have to drop it what oil do I buy in its place?

Thanks in advance James
