I guess I'm the first one to post a topic in this forum!</P>


Ok, I plan on doing oil changes inbetween my scheduled ones on my '04 XC90. I was wondering what everyone else uses for oil. Volvo recommends Castrol, but my dealer uses Motorcraft. I was thinking of just using Castrol GTX for the first 10,000 miles and then switching to Mobil 1. What do you guys think about this plan? The only thing that concerns me is the fact that the vehicle is turbo. Will Castrol GTX be good enough or should I use a turbo approved oil like Penzoil Turbo? Just cursious what you guys think.</P>

We have a great oil designed for use in turbo's , It outperforms Mobil 1 too.

ive heard that mobil one is good. i use quaker state or castrol gtx, and i am planning on trying out mobil one. i have heard that synthetic is better on the engine. if you are planning on changing oil in between what volvo recommends, you will be spending a lot on oil and filters, so buy something that is cheap but proven good (ie: mobil one).
