Synthetic Motor Oil, How Often to Change

The 3000 mile oil change has been ingrained into our minds since
we were knee high to a grasshopper and has turned into a habit.
Our grandfathers said “Change your oil every 3000 miles and your
engine will last forever.” That was true then and will work now
but is there a better way? Old habits are hard to break so
let’s examine the options.

The engines in our vehicles today are technological miracles
compared to the 1955 straight sixes, the 1969 327’s and the
Hemi. The back yard mechanic could easily change the points,
plugs, condenser, rotor and cap, complete and oil and filter
change in an afternoon. He was good to go for the oil for
another 3000 miles and 12,000 miles for the tuneup. Anyone who
had a set of Craftsman tools could take a jab at it and do an
adequate job.

Today just changing the spark plug is a four hour task when
performed by a qualified mechanic. There are so many components
squished into the engine compartment that three quarters of the
job is removing and replacing them just to get access to the
plugs. All this equipment under the hood has created an
additional problem of dissipating the heat produced by the
internal combustion of the engine. This heat must be reduced or
removed somehow so what has been done technologically by the oil
companies to address this? By considering our habit of oil
changes and the oil industries desire to sell more oil, not
much. They are happy to maintain the status quo for their bottom
line but there is a better way.

What has been done technologically? A great deal. Synthetic
motor oil is finally coming of age. Since 1877 chemists have
been working on formulas to use chemically manufactured mass
produced pure hydrocarbons to address the shortfalls of
naturally occurring petroleum oil.

The life span of synthetic motor oil is significantly longer
than its petroleum counterpart. The basestock is composed of
equally sized molecules each designed for maximum friction
reduction, high and low temperature stability, low volatility,
the amount of boil off, high viscosity indexes and oxidative
stability, thus creating a lubricant far superior to oil and
giving us the opportunity to increase drain intervals up to and
surpassing 30,000 miles. If you perform a regular engine oil
analysis to make sure your engine is performing properly and the
synthetic oil is maintaining its lubricating properties that
number is essentially unlimited.

When we talk about synthetic motor oil the company that is the
“first in synthetics” is Amsoil. Since 1972 Amsiol has been
producing Synthetic Motor Oil capable of achieving 25,000 mile
drain intervals and is the engine that is driving the Synthetic Oil
