sound(2) vehicles or equipment as follows:

Normal Service(3)
-- Up to 25,000 miles or one year, whichever comes first, or longer
based on oil analysis.
Severe Service(4)
-- Up to 15,000 miles or one year, whichever comes first, or longer
based on oil analysis.
Replace
AMSOIL Ea full flow oil filter at the time of oil change up to
25,000 miles (other brands at standard OEM* intervals).
Commercial
or Fleet Vehicles, Long-Haul Trucks, Marine Craft, RV, Off-Road
Equipment
Non-EGR equipped
diesels
-- extend drain intervals up to two times (2X) the OEM* recommended
drain interval or one year, whichever comes first, or longer based
on oil analysis.
EGR equipped or low
emission diesels
-- extend drain intervals based on oil analysis or use the longest
drain recommendation of the OEM*.
Replace
Donaldson Endurance or AMSOIL Ea full flow oil filters at the time
of oil change up to two times (2X) longer than the OEM* standard
interval, not to exceed 60,000 miles in long-haul trucks.
Gasoline
Engine Service
In
gasoline engines, oil drain intervals may be extended up to two
times (2X) the OEM* recommended drain interval (not to exceed 15,000
miles without oil analysis) or one year, whichever comes first.
Replace AMSOIL Ea full flow filter at the time of oil change up to
25,000 miles. Replace other brand oil filters at standard 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)
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 a properly
working emission control system. AMSOIL recommends repairs be made
to malfunctioning engines prior to the installation of AMSOIL
synthetic oils.
(3)
Personal transportation vehicles frequently traveling greater than
10 miles (16 km) at a time and not operating under severe service.
(4)
Extensive engine idling, daily short trip driving less than 10 miles
(16 km), frequent towing, plowing, hauling heavy loads or
dusty-condition driving.
AMSOIL Ea
and Donaldson Endurance full flow oil filters are designed for
extended drain intervals. They stop smaller particles, have less
restriction and last longer than regular filters. For best
performance, use AMSOIL Ea or Donaldson Endurance oil filters.
AMSOIL
by-pass oil filters are specialized for the removal of small,
wear-causing dirt particles, thereby extending engine life. AMSOIL
encourages using an
AMSOIL bypass filter system for maximum engine and oil life.
**Oil
changes (OEM) are recommended for use according
to the longest service interval established by the engine, vehicle
or equipment manufacturer. Drain intervals may be extended when
monitored by oil analysis. Recommendations for
Ford PowerStroke,
Dodge Cummins,
Chevy/GMC Duramax Diesel Engines. Request a free
