0W-30 ... 0W-40 ... or 10W-30 as we head into summer?

Will hit AutoZone and look for either Ryan's Castrol suggestion or this stuff. If I find neither on my lunch outing, will look harder for something to pickup on the way home.
Thanks

She's running a lot better w/ Mobil 1 0w-30 right now, very little turbo whine (siren). Mobil 1 0w-40 for summer will give better protection for the higher degree summer days.<ul><li><a href="http://www.mobil1.com/USA-English/MotorOil/Car_Care/Vehicle_Chooser/VehicleChooser.aspx?option=2">Mobil 1 Link</a></li></ul>

...I started off running RedLine 5w30 after hating Mobile 1 0w30. Then while on track, hit 300+ oil temps, so switched to Castrol TWS 10w60 to get the temps under control.
Added the RS4 oil cooler, that brought the normal temps from 250 to 200, then switched to German Castrol 0w30.
