GENERAL Lubricants and Lubricant Capacities Table
Use of fuels containing alcohol is not recommended
unless the nature of the blend can be determined
as being satisfactory.
Gasohol
A mixture of 10% ethanol (grain alcohol)
and 90% unleaded gasoline may be used in your
car.
If problems are experienced as a result
of using gasohol, it is recommended that the car
be operated on gasoline.
Methanol Do not use gasolines containing
methanol (wood alcohol). Use of this type of alcohol
can result in vehicle performance deterioration and
damage critical parts in the fuel system compo-
nents. Fuel system damage and performance prob-
lems, resulting from the use of gasolines containin g
methanol, may not be covered by the new car war-
ranty.
Gasolines containing
Ether)
Unleaded gasoline containing 15% or
may be used in car. Fuel containing MTBE
over 15% vol. may cause reduced engine perfor-
mance and produce vapor lock or hard starting.
MATERIALS
TO FUEL
Indiscriminate use of fuel system -cleaning’
should be avoided. Many of these materials in-
tended for gum and varnish removal
highly active solvents or similar ingredients that
can be harmful to gasket and diaphragm materials
used in fuel system component

Stall test consists of determining maximum engine speed
obtained at full throttle in positions. This test
checks torque converter overrunning clutch operation,
and holding ability of transmission clutches and
brake.
Caution
During this test, make sure no stands in front
of, or behind, vehicle.
1.Check the transmission fluid level, fluid temperatu re and
coolant temperature.
lFluid level: At “HOT” position on dipstick
l Fluid temperature:

4. Apply parking and service brakes fully.

6. With selector lever in position, depress accelerator
pedal fully to read engine
rpm. Do not hold
throttle wide open any longer than is necessary to obtain
maximum engine rpm reading, and never longer
5 seconds at a time. If more than one stall test is required,
operate at approximately 1,000 in neutral
for 2 minutes to cool transmission fluid between te sts.

7.Place selector lever to position and perform test
by the same procedures above.
Stall Speed Above Specification in
If stall speed is higher than Specification, rear c lutch or overrun-
ning clutch is slipping. In this case, perform hydrau-
lic test to locate cause of slippage.
Stall Above Specification in “R”
If stall speed is higher than front clutch of trans-
axle or low-reverse brake is In this perform
hydraulic test to locate cause of slippage.
Stall Speed Above Specification and “R”
If stall speed is lower than insufficient engine
output or faulty torque converter is Check for en-
gine misfiring, ignition timing, valve clearance etc. If these
are good, torque converter is faulty..
