Hi Leeg,
Smokey and Rob are giving you great advice and Rob has had a lot of experience on his own X5 and some issues too,especially loss of performance when can is warm and I hope he has sorted it.
Back to your car.One thing I can't see in your symptoms and feedback ,is whether the engine made the ticking noise before you changed the oil???
Regarding the oil you used,it's fine and the guys that favour Mobil1(Great oil ,used it in my M3E30)are mainly guys with M3s High revving and the viscosity is 10w60.
As the guys here already mentioned ,the Bmw recommended is 5w30 0r 0W40.The brand is commercial,so as long choose a known brand with Bmw specs,that's fine.I use BP7000 5W30.eventhough at work (Bmw dealer),we have to use Castrol Edge 5w30,so it's just a commercial thing.Been rumours that. Bmw will be changing to Shell .
A ticking noise can occur on higher mileage engines when you change from a higher viscosity oil,say from 5w30 to a lower viscosity,like 0w30,due to the latter being thinner and doesn't "fill in the gaps"of the
Wear and tear of the high mileage engine parts,where a thicker oil will and thus stop the ticking noise and excessive oil smoke.
Don't know if this is true in your case as I don't know what oil was in your engine previously.
This is only thing I can say at the moment,but if it's not your oil change,you need to look at other ticking noise possibilities:-
1.A loose or faulty injector (Quite common and something I already sorted for a member here)
2.Tappets (maybe spring is stuck preventing it from filling with oil)
3.Cracked manifold (facelift only and you should smell exhaust gases)
Look forward to your answer
