Hey Dan, do you know exactly what kind of oil is being put in the Caliber motors from the factory?

I'm wondering because I always run synthetic oil as soon as I take delivery. However it has recently come to my attention (see this thread at TheCarLounge.net http://forums.vwvortex.com/zerothread?id=2515790&page=1 ) that doing so may compromise the motor... or it may not. It looks like it may depend upon what happens at the factory.

How long is it recommended that the factory oil be left in the motor before synthetic is put in?

Will using synthetic too early harm the break-in period?

Is there any sort of precautions to take before using synthetic?

Thanks!

GOT... I put synthetic in my Neon...the thing started to knock...I quickly changed back to regular oil...the recommended viscosity, and the knock went away and hasn't been back...changed my opinion of synthetics...and I used Mobil 1

I'm not sure either...sounded like a rod knock...but it's gone now, and I will only use natural oil
