Why it is important to use the right oil
If you want better performance, or greater
reliability from your tractor it is essential that
you choose the right oil. Oil is important
because it prevents the wear and tear of the
mechanisms by creating a protective film
over the mechanical parts. Furthermore
it absorbs and disperses the heat, which
reduces wear and tear and thus protects the
engine and gearbox. A good oil impedes the
accumulation of dirt and deposits by keeping
then in suspension. Engine oil, for example,
protects against sludge and oxidation,
reducing acids that can provoke corrosion
to a minimum. The most frequent questions
about oil from our customers are:
What is oil viscosity?
What do the oil codes mean?
What are performance additives?
Viscosity
is an important parameter of every
lubricant. It is a measurement of the density
or flow resistance of a substance. For example:
honey is dense while water is fluid. Honey has
a higher degree of viscosity than water. The
viscosity of the oil must be suitable to the
tractor’s environmental working temperature.
If the oil is too dense when the engine is
cold, the engine won’t turn over; if instead it
is too fluid when the engine is warm, it won’t
guarantee the engine’s components the right
protection.
Therefore, optimising the viscosity of the oil
contributes to the optimisation of energy
efficiency thus avoiding wear and tear of the
components.
Multigrade oils are identified with two
numbers (
codes
) that refer to degrees of
temperature (for example 15W40). These
codes can contribute to performance stability
at high and low temperatures. The first
number of a multigrade oil is usually followed
by a W, which stands for winter. This number,
which represents the viscosity of the lubricant
at low temperatures, gives an indication of the
oil flow characteristics in winter. The lower
the first number the more fluid the oil at low
temperatures.
The second number, after the W represents
the viscosity of the oil at high temperatures;
the higher this number is, the denser the oil
remains at high temperatures. Using oil with
the correct viscosity improves the engine’s
performance, thereby reducing wear and tear
and increasing fuel efficiency.
Synthetic oils normally present better characteristics at high and low temperatures compared
to common mineral oils. In this way it is possible to keep protection constant with a greater fuel
saving and a better start up from cold.
Finally,
performance additives
provide added protection to the oil base. There are various
types to choose from and to carefully mix in order to guarantee high level performance.
Tony Gold Premium: magic formula made in AC
Thanks to extensive experience, the AC technicians have recently developed the lubricant “Tony
Gold Premium – High Performance AC Oil”, fruit of a (magic) formula that satisfies the highest
performance in any environment and in full respect of the Antonio Carraro tractor specifications.
