So they now meet GF-4 and still retain the 25k mile drain.

SERVICE LIFE
AMSOIL Synthetic 10W-30 Motor Oil is recommended for extended drain intervals in unmodified(1), mechanically sound(2) gasoline fueled vehicles as follows:
• Normal Service(3) – Up to 25,000 miles or one year, whichever comes first.
• Replace AMSOIL oil filter at 12,500 miles or six months, whichever comes first (other brands at standard OEM* intervals).
• Severe Service(4) – Up to 15,000 miles or one year, whichever comes first.
• Replace AMSOIL oil filter at 15,000 miles or six months, whichever comes first (other brands at standard OEM* intervals).
• In all other applications, extend the oil change interval according to oil analysis or follow the OEM* drain interval.
*OEM – Original Equipment Manufacturer
(1) Where the engine or operating conditions have been modified from the original manufacturers’ design, drain oil at the owner’s discretion or extend based on oil analysis. Examples include the use of performance computer chips; modified exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the manufacturers.
(2) Engines are in good working condition and within the factory design settings. Mechanically sound engines, for example, do not leak oil or consume excessive amounts, are not worn out, do not overheat, do not have internal or external anti-freeze leaks and have properly working emission control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.
(3) Non-turbo/non-supercharged personal transportation vehicles frequently traveling greater than 10 miles at a time and not operating under severe service.
(4) Turbo/supercharged vehicles, commercial or fleet vehicles, extensive engine idling, first and subsequent use of AMSOIL engine oil in vehicles with 100,000 miles or greater, daily short trip driving (less than 10 miles), frequent towing, plowing or hauling heavy loads and frequent driving in dusty conditions.
Notice, that the HT/HS score is now 3.2, and it no longer meets the A3/B3 specs.quote:
