AMSOIL BMK-21, Installation And Servicing Instructions

Page: 3 / 6

Installing an oil sampling petcock
on a spin-on by-pass:
Getting a clean and uncontaminated oil
sample is easy and simple when an oil sam-
pling pet-cock is installed into the Spin-On
By-Pass Oil Filter system. This can be easily
done by ordering a BP-67 Kit and installing
it into the by-pass system as shown here.
Oil Analysis:
1. If installing By-Pass Oil Filter with
AMSOIL Air Filter and 100% Synthetic
Engine Oil, in a pleasure vehicle we rec-
ommend the TRIGARD Oil Analysis
Program:
a. TRIGARD 1 (Stock No. ATG-01) is the starter pro-
gram. It contains registration material and 2
p prre ep pa aiid d analysis to check oil’s condition.
b. TRIGARD 2 (ATG-02) is for all subsequent oil
samples. Each ATG-02 also contains materials for
2 prepaid oil analysis.
2. For other oil analysis or commercial vehicles, order
G-1318 Oil Analysis Sampling Kits (in U.S., Canada).
Consult AMSOIL Technical Service for details.
By-Pass oil filter return-line fitting:
A swivel fitting can be installed directly on your oil filler
cap for the oil return-line from the AMSOIL By-Pass
Filter. This fitting can be used
(in most cases) instead of the
self-tapping hollow bolt, which
is usually installed on the oil
pan.
The Return-Line Fitting is made
of a sturdy brass-alloy and is
constructed so that the top of
the fixture can swivel. This
makes it easy to take off your
oil cap. The installation of the fit-
ting is simple and generally takes
5-10 minutes. Order BP-89. Be
sure there is not a PCV pick-up in
this area.
