The True Difference between Motorcycle Oil and Automotive
Oil by Chris
Nicholas
To some people, changing the oil in your car is just like
changing the oil in your motorcycle. Just drain out the old
oil, install a new oil filter, and pour in the desired amount
of new oil and your done. So when it comes time to change your
motorcycle oil, why can't you use the same oil that you use in
your car? Motorcycle oil and automotive oil look and feel the
same so how could there be a difference between the two?
Automotive oil looks pretty enticing at $3 a quart but any
experienced motorcycle rider knows that using automotive oil in
motorcycles causes serious damage. In automotive vehicles, the
engine is always separate from the clutch and transmission so
they have separate oils for each. In automotive engine oil,
there is more of what is called "friction modifiers" to help
lessen the amount of friction on engine components and improve
fuel economy. Of course, improving fuel economy has always been
the main goal of the automotive industry making friction
modifiers a necessity for all automotive oils.
These friction modifiers that are added to automotive oils are
what cause serious damages when used in motorcycles. The
friction modifiers clog the clutch plates in a motorcycle's
transmission causing serious clutch slippage and disabling the
motorcycle. You see, for motorcycles to be as compact as they
are, they have to combine their engine and transmission into
one casing. This means that everything is lubricated by only
one type of oil including the valves, piston, transmission, and
clutch.
Motorcycles require very little and/or no friction modifiers to
help improve clutch friction and to prevent clutch slippage.
But to make up for this lack of friction modifiers, motorcycle
oils use higher levels of anti-wear additives such as ZDDP,
also known as phosphorous, to limit engine friction and wear.
Since motorcycle oil has extra anti-wear additives and is
lubricating so much more than automotive oil, you can expect to
pay anywhere from $9 to $15 a quart.
To some people, both oils look and feel the same but now you
know the facts of each. So the next time that you decide to
change your motorcycle oil, go straight to your local
motorcycle dealer and buy only high quality motorcycle oil
designed specifically for the type of motorcycle you own. Make
sure that you change your oil periodically to keep it fresh and
clean to ensure a long life for your engine, transmission, and
clutch.
