I have switched over both my vehicles to Amsoil. I have a 2002 4.0L V6 SOHC Explorer and a 2007 Toyota Prius and both are now on what will be extended drain intervals with Amsoil. The Explorer is on 0w30 SSO and a Wix filter while the Prius is on ASM 0W-20 with an EaO filter.
The Prius is the daily use car and sees ~12,000 miles/year so I expect to change it out at the one year mark. The Explorer is now lightly used and I'll change it out at 5,000 miles which will be somewhere near the 1 1/2 mark.
