The AMSOIL Super Duty Oil Filter (SDF) is designed
to provide maximum filtration while meeting the high flow
demands of modern automobiles. The AMSOIL SDF contains
a special cellulose, synthetic and glass blend media that
offers the best possible balance of long life, high capacity
and overall efficiency.
Dirt Throughout Media Thickness
The AMSOIL SDF has a lofted fiber depth-type media
that traps dirt throughout its entire thickness for exceptional
filtering efficiency. It keeps oil clean and free of wear-causing
contaminants. The AMSOIL SDF Oil Filter provides up to
100 percent more capacity and up to 20 percent greater
efficiency than other filters provide. It is ideal for
use with extended oil drain intervals.
for Rugged Performance
The AMSOIL SDF has a heavy-duty case of drawn steel.
The case is double-crimped at the base with rolled-under
seaming to withstand extreme pressure surges and road
Oil Flow with Relief Valve
On most filters a relief valve is provided to assure
ample oil flow. It prevents oil starvation in the engine
in the event the media becomes saturated.
Oil Drainage During Engine Shutdown
On filter installations where the mounting is sideways
or upright, dirty oil could drain out of the filter when
the engine is shut off. The AMSOIL SDF has an anti-drainback
valve that keeps trapped contaminants in the filter when
the engine is not running.
AMSOIL INC. recommends changing the AMSOIL SDF
according to the following guidelines.
In gasoline-fueled engines using any AMSOIL motor oil
except AMSOIL XL-7500 Synthetic Motor Oil, change the
filter at 12,500-mile or six-month intervals. In gasoline-fueled
engines using AMSOIL XL-7500 Synthetic Motor Oil, change
the filter at 7,500-mile or six-month intervals. If a
Hastings or other filter is used, filter should be changed
at manufacturer recommendations.
In diesel-fueled large truck engines, change the filter(s)
at the engine manufacturer's recommended oil change interval.
In diesel-fueled light trucks, including pickups and vans,
change the filter at 7,000-mile or six-month intervals.
When using an AMSOIL Oil Filter with conventional motor
oils, refer to the owner's manual for the recommended
oil filter change interval.
