GENERAL MAINTENANCE
Check the fluid levels (particularly engine oil) on a
regular basis. Be sure to check the oil for grit, water
or other contamination. A vacuum gauge is another excellent indicator of
internal engine condition and can also be Installed in
the dash as a mileage indicator.
44. Periodically check the fluid levels in the
engine, power steering pump, master cylinder,
automatic transmission and drive axle.
45. Change the oil at the recommended in
terval and change the filter at every oil change.
Dirty .oil is thick and causes extra friction be
tween moving parts, cutting efficiency and in
creasing wear. A worn engine requires more
frequent tune-ups arid gets progressively worse
fuel economy. In general, use the lightest vis
cosity oil for the driving conditions you will en
counter.
46. Use the recommended viscosity fluids in
the transmission and axle.
.47. Be sure the battery is fully charged for
fast starts. A slow starting engine wastes fuel.
48. Be sure battery terminals are clean and
tight.
49. Check the battery electrolyte level and
add distilled water if necessary.
50. Check the exhaust 'system for crushed
pipes, blockages and leaks.
51. Adjust the brakes. Dragging brakes or
brakes that are not releasing create increased
drag on the engine.
52. Install a vacuum gauge or miles-per-
„ gallon gauge. These gauges visually indicate
engine vacuum, in the intake manifold. High
vacuum = good mileage and low vacuum =
poorer mileage. The gauge can also be an ex-
cellent indicator of internal engine conditions.
53. Be sure the clutch is properly adjusted. A
slipping clutch wastes fuel.
54. Check and periodically lubricate the heat
control valve in the exhaust manifold. A sticking
or inoperative valve prevents engine warm-up
and wastes .gas.
,
55. Keep accurate records to check fuel
economy over a period of time. A sudden drop
in fuel economy may signal a need for tune-up
or other maintenance.
