We are no longer recommending the AMSOIL EA15K50 Oil Filter for
2007-2013 GM vehicles with the 5.3L engine and 2013-current Ram vehicles with
the 5.7L or 6.4L engine. There is no cause for alarm if you or one of your
customers is using the EA15K50 Filter with one of the listed vehicles; we are
acting out of an abundance of caution. We have sold thousands of AMSOIL EA15K50
Oil Filters to customers with one of the GM or Ram engines listed above. A very
small percentage of those customers have reported gauges or check-engine lights
indicating slightly lower than normal oil pressure.
Our industry-leading high-efficiency media removes more particles
of smaller sizes than most competing filters to better prevent engine wear. In
the GM and Ram applications listed, the EA15K50 Filter is capturing a large
number of deposits and reaching its holding capacity before the end of its recommended
service life in a small number of instances. This can result in reduced flow
and overall oil pressure, but in no way harms the engine. AMSOIL Oil Filters
include a bypass relief valve to ensure appropriate oil volume is always
delivered to critical components.
Rather than cause some customers unnecessary concern, we are
recommending the WIX 57060 or Donaldson P550794 in place of the EA15K50 in
2007-2013 GM 5.3L engines and 2013-current Ram 5.7L and 6.4L engines. They are
high-quality filters, but will not capture as many small particles as the
AMSOIL Oil Filter does, and they are designed for shorter service intervals.

Technical Services at [email protected] or (715) 399-8324 (TECH).
FAQ
I used the EA15K50 Oil Filter with one of the affected GM or Ram
engines before. Can I continue to do so?
Yes, but it should be changed at the vehicle manufacturer’s recommended change
interval. We no longer recommend this filter for up to 15,000 miles (24,000 km)
in these engines.
Did using the EA15K50 Oil Filter harm my vehicle?
No. The filter includes a bypass relief valve to ensure appropriate oil volume
is always delivered to critical components.
Can I still practice extended drain intervals with Signature
Series Synthetic Motor Oil in these engines?
Yes, but only if you change the WIX or Donaldson filter at the manufacturer’s
recommended service interval and top off the oil after the filter change.
Is there any benefit to using Signature Series Synthetic Motor Oil
if I don’t want to change filters to get extended drain intervals?
Yes, Signature Series contains a robust package of detergents and dispersants
to protect against the deposits produced by these engines.
What can I do to combat these oil deposits?
We recommend using Signature Series Synthetic Motor Oil and changing the WIX or
Donaldson filter at the manufacturer’s recommended interval. We also recommend
using AMSOIL Engine and Transmission Flush every-other oil change.
Will AMSOIL offer another extended-drain filter for these engines?
We are conducting additional research and development with the goal of once
again supplying a high-efficiency, extended-life filtration option.
