Being the Diaqueen LSD SAE90 is the only oil recommended for our T-Case and Diff this is bad news. I contacted both Shep and Jacks and there is no 100% solution. Motul 90PA is the next best thing but neither shop has tested it.


"Sorry but Mitsubishi has just been notified by the U.S. Government that they can no longer sell the GL5 they make due to too high levels of toxic materials. All units have been recalled back and there has been a cease and desist from selling it."

 

As someone who uses only OEM fluids for the tc, trans, and diff, this is crappy news. Luckily, there are companies like Redline who have our backs. It may not be the same stuff, but it's GL-5 and it works well. TRE recommends this if not using OEM. The good news is that you can use this in your TC and rear diff.

Any links or source for this?

 

Unfortunately no but the dealerships/Jacks/Shep are all tracking it and unavailable to sell it

 

Haven't heard exactly stellar reviews of Redline products from my tuner, this is disappointing news.

 

I'd like to see some more sources for this info.


*edit*


Found it:


----
Subject: URGENT Stop-Sale on Part# MZ320345 LSD Gear Oil

On December 19, 2017, MMNA was notified by JX Nippon Oil & Energy Corporation that LSD Gear Oil GL-5 SAE 90 (Part# MZ320345) does not comply with the EPA’s Toxic Substances Control Act (TSCA).

Terrific.

 

... So what are dealerships going to tell you when you go in for the regular fluid change?

 

My advise is to go to your local dealership and try and get some NOW. I went yesterday and they sold me 2qts. Hopefully by my next change Mitsubishi will have figured this out.

 

I'm hoping to pick up 2-4 quarts to hold me off another year or two.

 

Hey if you're in Canada you probably have nothing to worry about since the EPA has no jurisdiction there (far as I know.)

 

see sig. use redline

 

Checked sig.


Found a bunch of Photobucket Account upgrade required images.


Nice job.

 

You can try anything you want in there but I guarantee there is no company or "tuner" shop anywhere that knows more about these drive trains than Jacks or Shep. They both 100% recommend you don't put ANYTHING in there but OEM. I take there advise WAY before anyone else.

try reading it again, at least until the bottom of the FIRST POST, which relinks to all the images.

nice job.

idk about jack or shep, but i talk to jon@tre regularly. when i did these voa's (on my own dime), i talked to him about it. we discussed updating tre's recommendations, and i ultimately told him not to. why? because there's no benefit in it for him. if i were a trans/gear shop, there is no way i would recommend anything but either oem or the thickest aftermarket fluid. why not?

 

Same with Kozmic Motorsports here in Houston. They scoff at ANYTHING but Diaqueen...so....yeah.

I think only solution = make Canadian friends and have them ship it over
