Got yourself a nice new vehicle? And
you want it to last a really long time? Considering the use of synthetic
lubricants to get the most life out of your investment? Here's what I
recommend
For gasoline
engines, the first five hundred to one thousand miles should
be driven on the factory filled oil. At this point I recommend
changing that oil and filter to your choice of synthetic motor
oils and a quality high efficiency oil filter. Changing the factory filled
oil and filter early removes contaminants and particles left from the
manufacturing process.
Now you may
wonder why so few miles, what about break in? The fact is with modern
metallurgy and manufacturing techniques break-in really doesn't take as long as
it used to. Without being too technical, engine break in has as much to do with
how many heat cycles (how many times the engines been hot and cold) as does the
number of miles driven allowing the parts to "wear in." Put the
synthetic in at five hundred to one thousand miles, your engine will be just
fine and live much longer too!
Can I just put synthetic
oil in the engine right away?
Yes, you can and many engines are factory filled with synthetic oil.
However because petroleum motor oil has lower film strength it is
actually better for breaking in the engine than synthetic. Particularly with an
older engine that has been overhauled.
What about
the transmission and differential(s)?
Essentially
there is no need to wait. Automatic transmissions, manual
transmissions, transfer cases and differentials can be changed right a way. If your
vehicle has an automatic transmission and most of your driving is city use
changing to a synthetic automatic transmission fluid can dramatically extend
the life of your transmission. Consider that
with stop and go city driving your transmission is constantly shifting up and
down through the gears and transferring torque load from dead stops through the
transmissions gears. A big workout for your transmission! This is even more important
for commercial vehicles hauling loads in city use such as vehicles in a
delivery fleet.
Synthetic
automatic transmission fluid provides much greater protection from wear and the
high temperatures of stop and goes driving or from pulling heavy loads than
conventional petroleum transmission fluids and can greatly extend the life of
the transmission. Very high quality PAO (polyalphaolifin) based synthetic
fluids have the added benefit in that they dissipate heat faster than
conventional transmission fluid and will lower operating temperatures by as
much as twenty to fifty degrees. Automatic transmissions are most easily changed on a fluid
exchange machine which thoroughly replaces all of the transmission fluid
including what’s in
the torque converter removing the vast majority of contaminants at the
same time. Many auto shops and oil change centers have fluid exchange
machines for changing out the fluid in automatic transmissions and over the
life of your vehicle it is worth paying the cost having the fluid changed out.
