engine noise after oil change
i just purchased a 01 t/a and changed my oil for the first time. it had 10w-30 conventional oil and i put royal purple 10w-30 in it. on inital start up it had a slight knock that i had not heard before but went away after a few minutes. but now every morning it does the same thing and i was wondering if it had something to do with oil or weight of oil? any suggestions?

welcome to the world of ls1's (that is the type of motor you have) mine does it along with many other members on here. its just a valve tap or piston slap and its nothing to worry about. just make sure you have good oil pressure and your good. if you really hate the noise try amsoil...i have heard that it helps the piston slap a little. hope this helps

Try to find the German made Castrol Syntec. It's a 0/30 synthetic, and you can find it at Autozone. Use the bigger Wix filter, and run 6 quarts. I've had NO knock OR consumption issues, and I run it for 5k miles.
