[Roadsters] Changing transmission fluid...UH OH

[Embarq Customer]

>From an internet post.B  B 



"We asked Valvoline if it was ok to use their DuraBlend Gear Oil (a GL5 oil)
in a Nissan 240sx manual transmission that requires GL4 spec oil.

They replied with this: "



"Absolutely, all Valvoline Gear Oils can be used for both GL4 and GL5. The
concern is the type of sulfate used in the gear oil, as you can not use an
active sulfate for GL-4 applications. Valvoline uses an inactive sulfate
that will not harm any yellow metal such as bronze. This allows our products
to be used in manual transmissions that have bronze synchronizers."



You might want to write to Valvoline.

Only GL-4 !!!???B  The newer GL-5 oils will eat my syncros!!???
IB  just checked the fine print on my bottle of Valvoline 80/90wt gear oil...
that I just used!!... and it's GL-5.B  My specs say "GX", but my research
revealed that it's an obsolete code.B  The older gentleman at "Orange Engine"
concured it's obsolete,B  and recommended this Valvoline, stating it was the
equivalent.B 
Is there a difference in what to use between the 1500 and 1600s?
I've used GL-5 in my differencial and steering box, too.
Now what?B  Do I need to remove all the GL-5 from my car?
Do I have to flush? and if so, with what?
Yikes!B  I guess I should have known that this wouldn't be straight forward.
