What is best engine oil and filter for kia-rio 1.4 EX automatic in Ireland (cold weather).

You could but most of the time it never works or it works for a short period of time. There is of host of oil filters and oil additives that you could use. You say you are in Ireland, I'm not familiar with the products that are sold there. So my recommendation would be to use a named brand oil filter, oil and additive to the car.

Thanks firebird338. Also is there any special oil filter i need to use.

They all are pretty good but I prefer Fram oil filter and castrol oil but it is just a personal preference.
