NO, you should probably change your oil at least after first 2K miles or do it when you can SEE the right moment. Long story...but I'm sure everyone can tell you more than I can. Old topic.....<P>I switched to Synthetic after 5000K on my car. Used GTX after first oil change.

At the time -- I believe -- the company recommended at least 6,000 miles on new engines before switching to synthetic, and we have continued to follow this guideline on all subsequent new cars.<P>Ciao,<P>Larry<P>
Volvo recommends NOT using a Synthetic for the first 10,000 miles. I think this is in the manual, but I heard it from the dealer that sold me the car, and also from a different dealer where I get my oil changed.<P>As for which brand synthetic: I use Mobil 1 because Mobil seems to be committed to synthetics (they have had a complete line for a long time, including a lot of commercial products), as opposed to the various "me too" offerings from some of the other companies. Also, I prefer Mobil 1 over brands such as Red Line and Amsoil for convenience (Mobil 1 is readily available at many retail outlets). However, I have no credible evidence that any brand is better than any other brand. If I had such info, I would certainly go out of my way to use that brand.<P>
Break in is between 1500-2000 miles, depending on how you drive, and that is plenty with todays high tolerance engines. <P>As for Synthetic oil, Amsoil 0W-30 Series 2000 is bar none the best for Volvo turbo's or non-turbo's for that matter. I used Mobil 1 for 6 years and it is very good oil, far better than Castroil Syntec (as Castroil is not 100% synthetic stock), but the Amsoil additive package is far better, thus the 35,000 drain interval (not that I would go that long myself) and Amsoil has a considerably lower wear scare diameter with the four ball wear test (universally accepted SAE test for oils). Just do the research yourself. Drawback is that it's abut $8.50/quart. <P>As for commitment to synthetic, Mobil was before everyone (Except Amsoil) which was the first company to make synthetic automotive motor oil.
