Oil for my (new) 2002 X5 3.0i

[MiRH]

I've recent bought my first X5, a 2002 3.0i.

Despite it being looked after previously, the oil currently is rather black and a bit sludgey so i am going to drain and change it.  I've gone for 0w-30 castrol edge, which i'll add a Slick 50 or Wynns Oil boost to.

There shouldn't be any major issues with that right, i know 5w-40 is the default?  The car has just crept over 148k miles.

Morning Matt

Welcome to the forum I hope you enjoy your X5

There are many debates on oils but as long as it meets BMW LL ACEA A3 spec it should be fine. If I recall in the hand book it gives a pretty wide range of oils to cover all geographic locations.

I use 5W 30 fully synthetic I have read that additives can cause lazy lifters but have no personal experience, I may go to 5W 40 fully synthetic now mileage is over 100k

Hi Matt....welcome to the Forum

I totally agree with Greydog on his judgement with the oil specs and the fact that your X5 has done a higher mileage I don't think I would go with the lighter grade...best to go with the 5w40 and you shouldn't need any additional additives if you get a quality oil (Mobil1, Shell, etc)

Let us know how you get on with it all.  Cheers,  Trevor
