You can not keep an
engine in good shape with a cheap oil. You say "you are going to keep
your engine clean and bright." Not if you must use a poor oil.
Poor oil is largely responsible for the fast going out of use of the
link reverse among the makers of traction engines. While I think it
very doubtful if this "reverse motion" can be equalled by any of the
late devices. Its construction is such as to require the best grade of
cylinder oil, and without this it is very unsatisfactory, (not because
the valves of other valve-motions will do with a poorer grade of oil)
but because its construction is such that as soon as the valve becomes
dry it causes the link to jump and pound, and very soon requires
repairing. While the construction of various other devices are such,
that while the valve may be equally as dry it does not show the want of
oil so clearly as the old style link. Yet as a fact I care not what the
valve motion may be, it requires a good grade of oil.
You may ask "how am I to know when I am getting a good grade of oil."
The best way is to ascertain a good brand of oil then use that and
nothing else.
