I skimmed the FAQs and decided that since I have plenty of it in the garage I would try it out. It is exactly what Honda recommends specification wise (GL5 hypoid 90w gear oil). Mitsu part number is 3775610, commonly referred to as Diaqueen.

I will update this thread with my experience.

 

^ good stuff, awaiting follow-up info.

 

interesting...

is there anyone that can compare it with le 1605?

 

Face it folks it will be a meaningless test:
1. Works fine, would have worked fine with anything else. (Just like Torsen says)
2. Fails, and we can't tell if it was the fluid (unlikely) or the driver (much more likely) or random manufacturing tolerance.

roadrage would have done a quantitative, additive, composition type analysis and recommendation.

 

At $50 per 4 liters, it's a bit more expensive than LE 1605.

 

^
no it wouldn't be.

 

Ultimately you're right. Not a great test unless the diff fails and even then it would be hard to deduce anything meaningful. Regardless, I'll jack up the rear and rotate one wheel to see if I can feel any difference before and after.

I'm it'll work because the specs match up and it's fine in the Evo's front xfer case, torsen diff, and rear clutch diff.

Yes, its SAE 90 GL-5, but what about viscosity @ 100C, pourpoint, is it synthetic oil or dino, any ASTM test results?
I could not find anything about that online.

Anyway.. do you, cracknut, know if the Mitsubishi EVO owners manual mentions anything about not using this oil in colder climates?
And I'm NOT talking about the Arctic climate, just the below freezing mornings.
My guess is: no.

 

question. is the mitsu diff a torsen?

if its a clutch type LSD, dont use the fluid.
