I had a great UOA with Amsoil ASL 5W-30 in my Acura. I did notice that the Amsoil oil filter I was using at the time (the EaO20) took longer to build-up oil pressure when compared to other filters I've used on the car. The oil light would take a good 2-3 seconds to turn off, whereas it usually only takes a second. Perhaps the ADBV was a bit weak, but it didn't seem to affect anything wear-wise with the UOA. I believe they call it Signature Series oil now instead of ASL. I should note that this was during a very cold winter, where I started the car in temperatures of colder than -25F, though the oil light issue happened even when it was above freezing.
Edit: Forgot to mention that I've used their ATF in my Acura's transmission since I got it at 120k miles and it's still shifting great. I've also put it in my girlfriend's 2001 Civic, which has a trouble-prone transmission. Amsoil's ATF is second-to-none, IMO.
