I have a couple of those but the older ones without the updated ADBV. Being a 95% filter it will never be on my Toyota I'll likely give them to my stepson he isn't so fussy. His Corolla has 260K plus on it. Nice tool I got one of those for Christmas.
Considering its efficiency is roughly twice as good as the OE Toyota filter (as near as we can tell via the AMSOIL data)
The February 2011 Amsoil study sure has legs. But, until Toyota states otherwise, I guess that is about all we have to go on. Meanwhile, I will continue to use that poorly rated filter and see how far I can take our RX330.
