Who is recommending running ASM for 35,000 miles? What disaster happened?
SERVICE LIFE
AMSOIL Synthetic 0W-20 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.

• Severe Service(4) – Up to 15,000 miles or one year, whichever comes first.

• Replace AMSOIL Ea Oil Filter at the time of oil change, up to 25,000 miles or one year service life, whichever comes first (other brands at standard OEM* intervals).

• In all non-gasoline fueled vehicle applications, extend the oil change interval according to oil analysis or follow the OEM* drain interval.

*OEM – Original Equipment Manufacturer

(1) Engines operating under modified conditions are excluded from extended drain recommendations. Examples include the use of performance computer chips; non-OEM approved exhaust, fuel or air induction systems; and the use of fuels other than those recommended for normal operation by the manufacturer.

(2) Mechanically sound engines are in good working condition and do not, for example, leak oil or consume excessive amounts, are not worn out, do not overheat, do not leak anti-freeze and have properly working emission control systems. AMSOIL recommends repairing malfunctioning engines prior to the installation of AMSOIL synthetic oils.

(3) Personal vehicles frequently traveling greater than 10 miles (16 km) at a time and not operating under severe service.

(4) Turbo or supercharged vehicles, commercial or fleet vehicles, excessive engine idling, first and subsequent use of AMSOIL in vehicles with over 100,000 miles, daily short trip driving less than 10 miles (16k), frequent towing, plowing, hauling or dusty condition
driving.

Again, what risk? AMSOIL has made these claims for 38 years and the oil has not failed yet. And if the oil does fail, AMSOIL covers parts and repair with their warranty.

Again, just follow the Service Life recommendations, and all will be fine.
