Some Important Questions

[Jeff5886]

Hello all,

I am new here and had some basic questions. But before I ask; I have a 2001 X5 with the 4.4 and about 70k miles.

Ok questions.....

1. I have read that I can use 0w40 Mobile 1 full synthetic. Is this ok to use in the hot Arizona sun, or would you recommend some other type of oil? Does it need a special filter?

2. If I park the X5 and come outside from letting it sit parked, it will lean to the right. As soon as I unlock the car with the keyfob, it starts to level itself out. What is going on?

3. A Service engine light came on today. P0492. I have read that it has to do with the secondary air pump. Where is that and how do I test it?

Thanks,
Jeff
