High Speeds
are more than danger-
ous. At 70 miles per hour your motor uses almost twice as much
gasoline, to go one mile, as it does at 20 miles per hour. Econom-
ical cruising speeds are
30
to
45
M.P.H.
Soft Tires
are hard on your gasoline
bill. They mean more road friction. This gives your motor un-
necessary work to do and makes it use extra gas. Keep the extra
money in your pocket by keeping your tires inflated to the
recommended pressures.
Parking in the Sun
wastes gasoline.
Park your car in the shade, if you can, so that the hot sun will
not evaporate gas from your tank.
An Idling Motor
is a useless expense.
Turn it off while you are waiting at the curb for a friend, or at
a train crossing.
An Inefficient Carburetor
is an
efficient gasoline waster. Have yours checked at least twice a year
(for summer and winter driving) to be sure it is properly adjusted,
that the octane selector is properly set, and that the sediment
bulb is clean.
Cheap Lubrication
is a waste of
money. Use oil of good quality and of the grade specified by the
manufacturer. Have your car well greased every thousand miles .
. ' One Faulty or Dirty Spark Plug
may waste much of your gasoline.
An Over-Full Crankcase
wastes oil
and does not give you better lubrication, despite theories you may
have heard. Keep your oil level within the limits marked on the
oil level rod
in
the crankcase.
To Obtain Maximum Efficiency
and greatest gas mileage, have a complete motor tune-up per-
formed every 5,000 miles or at least twice a year .
