What Oil Do You Use for Diesel Engines?

[Krzysiek79krzysiek]

I was recently changing the oil in my 3.0d GU4 2005 and was looking / reading a lot in the nissan manuals about it. It needs to go with "turbo diesel" oil and as far as API it depends what is the coldest and hotest temp around your area of driving. I am leaving in Poland where during winter (Jan-Feb) we can have -30C and during sommer months (Jun-Jul) it goes up to 35C ... So it is recomended to use 5W40 - and I used this time Castrol Magnatec Diesel 5W40, though it is C3 type not B3 - but same CF type so good for diesel engine with turbo. I know from these Guys (who are maintaining mostly patrols) that with Castrol GTX and with Castrol Mgnatec (both diesel with turbo) they never had issues. They told me that for 3.0 CRD there is other than CF type but I don't remember now. It is the same if not more important if you use good quality oil filter not the cheapest one from ebay... and you need to take into consideration the outer conditions as well as driver - driving style. 10k kms and 1 year is not the only time you shall chng the oil.
