your motorcycle is covered under a regular or extended warranty,
you may at one time or another, from either the Dealer or the
service department heard that using Synthetic or any other oil,
other than OEM type lubricants, will void your warranty. Nothing
can be further from the truth. As long as you use a lubricant/oil
which meets or exceeds the standards and designations set forth
in your service manual, No Dealer or Manufacturer can void your
warranty. This practice is misleading not to mention illegal.
There is a law in place called the Magnusson-Moss Act (MMA)
that restricts Manufacturers and Dealers from this practice.
It is as follows: THE MMA-"(c)
No warrantor of a consumer product may condition his written
or implied warranty of such product on the consumer's using,
in connection with such product, any article or service (other
than article or service provided without charge under the terms
of warranty) which is identified by brand, trade, or corporate
name; except that the prohibition of this subsection may be
waived by the Commission.
If - (1) the warrantor satis-fies
the Commision that the warranted product will function properly
only if the article or service so identified is used in connection
with the warranted product, and (2) the Commission finds that
such a waiver is in the public in-terest." ( 42 U.S.C.
Basically what the MMA does is prevent
manufacturers from forcing consumers to use OEM lubricants/oils,
and or, OEM parts to maintain warranty coverage, unless the
oils or parts are provided Free of Charge by the manufacturer.
This law also keeps manufacturers from charging outrageous prices
for OEM equipment. Most parts, accessories, oils, etc are available
through the aftermarket, and when manufactured by a reputable
company, they typically meet or exceed OEM specs.
