Well I couldn't help myself and I just had to know, so I poured in a 12oz bottle of STP oil treatment. I know it's sacrilege, but I figured the small amount of STP wouldn't significantly affect the overall performance of the more than 5 qts of AMSOIL in the engine.

I then drove the same road under the same conditions and guess what? The increased clicking was eliminated. When I popped the hood the engine sounded the same as it normally does.

I intend to run the AMSOIL for 15k miles and change it again, but with a difference. I'll put in 3 qts of the 0w30 and 2 qts of their 5w40 Euro spec oil.

Hopefully, this will give me the same results as adding the STP, but with the benefit of 100% synthetic oil.
