RedLine MT-90 oil for manual transmission?
 
Ok ... I just found out some bad news, and I wanted some good advice.

I've got a '91 XJ, with an AX-15 manual tranny. It has brass synchro rings.
The owner's manual calls for GL-5 gear oil.

I just read that was a mistake ... they ran that info for about 2 years,
then changed it to GL-3 oil.

Turns out, the sulfur and sulfite additives in the GL-5 grade oil eat up the
brass synchros.

Anybody else heard that?

What about redline MT-90? is that good? Will it do any damage? Thanks in
advance ... any info would be appreciated ... even if it's not directly
related ... :-)

Redline MT-90 is ideal for the AX-5 and AX-15 transmission, I'm using it
in my own AX-15. You're right that GL-5 is not good for the synchros,
the sulphur-based additives contained in most GL-5 lubes are harsh on
soft yellow metals like brass.

Re: RedLine MT-90 oil for manual transmission?
 
P.S. Bill's webpage is outdated as it is still showing that GL-5 is
recommended for the AX-5/15. Chrysler rescinded that GL-5
recommendation probably 5-6 years ago, changing it as you said to GL-3
which does not contain the harmful additives present in GL-5.

Re: RedLine MT-90 oil for manual transmission?
 
Six years ago Daimler switch to the New Venture 3550 manual
transmission, using their own oil or equivalent:
http://www.pennzoil.com/products/gea...cro_fluid.html GL-5 is
still recommended for their differentials
Sulfur is a necessary evil of petroleum products, but if you want a
heavy duty lube choose GL-5 as Mercedes:
http://kenoanyag.mol.hu/english/prod...kkei/doc123807
A light duty lube such as GL-3 would be a good choice for a mall poser,
as you.

Re: RedLine MT-90 oil for manual transmission?
 
Hi Bill:

Thanks for posting that info ... but it's outdated. Chrysler recommended
GL-3 in their earlier jeeps, then switched to GL-5 when that new spec came
out. Afterwards, they learned that the sulfur and sulfite additives in GL-5
lubes are highly corrosive to brass synchro rings, which are found in the AX
5/15 trannies.

Chrysler rescinded the GL-5 recommendation about 8 years ago, and has
switched back to GL-3. Check with your dealer service dept ... they will
verify it.

Does anybody know if Redline MT-90 (synthetic, GL-4) has sulfur or sulfite
additives?

Thanks!!

Re: RedLine MT-90 oil for manual transmission?
 
Hi Bill:

Pennzoil synchromesh is not a GL-5, nor is the Daimler/chrysler oil. GL-5
is great for differentials, as you said, because they have no soft yellow
metals. GL-3 fluids are better for manual trannies with brass synchros,
because it has so much less sulfur & sulfite additives in it.

Call your dealership service desk, they will verify it. Normal GL-5 dino
oil is quite harmful to the AX 5/15 trannies.

Re: RedLine MT-90 oil for manual transmission?
 
I find it interesting after thinking about the possibility of
corrosion happening in a transmission bath in gear oil, so I Googled it:
http://www.google.com/search?hl=en&q...e+transmission
and found nothing, but AMSOIL and other snake oils! Then they call the
brass sync rings "yellow Metal" I guess for litigious reasons. Total
Bullsh*t!

Re: RedLine MT-90 oil for manual transmission?
 
Neither Redline's MTL nor MT-90 contain any of the harsh sulphur-based
additives, both are great for the AX-5. MTL for really cold areas,
MT-90 for the rest of us. :)
