Hi all. Look on the bright side.  Maybe they will let you buy the ones
that fail the test and you can buy them for a song and reseal with the good
stuff and put them in your plane and never look back.

ha ha wyo. walt.

-------------------------------------

Unfortunately they intend to rebuild them instead of selling them.
If they did sell them they would be an excellent buy as
the only thing wrong would be a slightly leaking oil O-ring
or two.

I forgot to add the clue about hot climates. No doubt
the oil is overheating.

Paul Lamar ...No rotor no motor.

More mis info.

http://www.autoblog.com/2006/08/24/mazda-to-recall-the-rx-8/

"Mazda claims that the problem is brought on by hot climates or
the usage of synthetic oil. If the oil is allowed into the
combustion chamber, it eventually reaches the catalytic
converter and causes a malfunction of that emissions-control device.

[Source: Rotary News]"

What do they mean "if"??  The RX8 engine sucks oil out of the
oil pan and injects it into the combustion chamber
of course the oil reaches the combustion chamber.

Don't let the dealer tell you they will not fix your engine
because you used synthetic oil. When I bought my RX8 I specifically
asked the dealer and the Mazda Japan PR person if they objected
to synthetic oil. They said no but they had not tested it.
The very large Japanese oil company Idemitsu manufactures and sells
synthetic Rotary Engine oil that is specifically formulated
for rotary engines.


Paul Lamar ...No rotor no motor.


Many manufacturers ship their new cars with synthetic now because they
want the best possible mpg numbers on the sticker.... I would not be
surprised if Mazda did as well.
