Hi Valleys

It should tell you in your Warranty and Maintenance handbook. When we had a 2003 C3 1.4 petrol 75bhp, I used Castrol Magnatec 5w30 A1 which was to the right oil spec. Supermarkets and Halfords sell it so it is not too expensive and being a full synthetic helps with the 2 year / 20k mile service interval if you risk going that long. It also never went black between oil changes. Before I started servicing it the Citroen dealer used Mobil formula P 5w30.

 

The Comma oil link suggests a 5w40 oil for that C3, so a bit different to the handbook and dealer but for our current cars it comes up with the same specs as the handbooks.

 

If you want to use a Total oil you should pick the full synthetic which I think is 9000.

Brilliant thanks for replys. Another thing is reason im asking about oil I think I have a leak somewhere seems to be using alot of oil. I will put a picture up now looks to be like a pipe is kinked if you can see it in photo.

Are you sure it is a pipe and not insulation around the wiring. I vaguely remember it breaking up on our old C3 but did not bother replacing it. It can get soaked with oil as the filter is changed.

 

The petrol engine is known for oil leaks from an oilway in the head gasket at the left end as you look at it from the front. There is a rubber seal in the gasket that can perish and to sort it if it is bad, the head gasket needs replacing.

 

Other possibilites for an oil leak include the sump drain plug if the washer on it is not replaced (less than £1 from a dealer) on oil changing, the oil filter itself if the top is not torqued up enough (might be 25Nm, it tells you on the top) or the oil filter top seal is not renewed or put on properly. It should be possible though to trace an oil leak.

 

If the engine is using oil and not leaking it, then this could be the head gasket again or wear in the engine. Look for oil in the coolant expansion tank and smoke from the exhaust when accelerating, especially after going down a hill without using the accelerator and also on first start up in the morning. If the oil use is due to wear and is not great then most people would live with it.

 

I edited post 3 since you last posted so you may want to look at it again.

The reason Comma site is a better choice for your grade of motor oil than say, a user manual or owners handbook etc, is that Comma have regular updates by all manufacturers on the latest grades of oil recommended for any given vehicle.

It is amazing how oil grades change over the years, even some times on the same car with the same engine which you have probably replenished the oil many times before.

 

9 times out of 10, your intuition of which oil to use will stand you in good stead, but manufacturers can change the spec of recommended oils at short notice. I know from my own experience that many times I have assumed that the oil was the same on similar models with slightly different engines, only to find that I was completely wrong. A good example is the VW range where the oil for the PD engines is totally different to the TD engines (and considerably more expensive). I just think it's best to be sure.
