Ziggyrama, You have 5000 total miles on the vechile it is kind of too late now to try to re-break it in! To be honest I think your 1000 miles OEM break in should be enough. I do not think going back to conventional oil at this point with 5000 miles on the clock is going to do anything for you! You might try S3K 5W30 or their 5W40 and see if this helps!
You could always give it a try but would be wasteing the price of the Amsoil oil! So many oils are now group II,II+,III with some ester added in etc...
P.S. You can also try driveing it harder for a couple of months! Down shifting a bit more etc...
