LAWN-BOY OIL TEST CARDS
Easy to use when demonstrating to customer the
proper fuel/lubricant mixture.
Occasionally it is necessary
to
provide visual evi-
dence that an insufficient amount of lubricant was
mixed in the fuel. Using
this
card will help to deter-
mine if the mixture was or was not correct.
TEST PROCEDURES: Determine what kind of
oil
and gas the customer
was
using. It then becomes
necessary to correctly mix the same kind of
oil
and
gas in the recommended ratio.
(32:l
or
16:l)
14-16
REVISED
Place a sample of the customer’s mixture in
#2
circle and a sample
of
the correct mixture in
#3
circle.
Place a sample of straight gasoline in
#1
circle.
Gasoline evaporates very quickly. When gasoline in
#1
has evaporated, it
will
also
have evaporated from
#2
and
#3.
The circle with the darkest appearance
will
have more
oil
than the other. This test should be
made
in
the presence of the customer to eliminate
doubts of the results.
Use
as
an aid for selling Lawn-Boy Lubricant.
