Transfercase Fluid....Still Unanswered
there really aren't that many different oils to choose from that are equivilent. the most important parameters are GL-5 and straight 90 weight, that combo is hard to find, don't forget it also needs to be a hypoid gear oil and the only kind i have found to meet these three requirments besides diaqueen LSD oil is royal purple maxgear 90 weight.

On one hand you have Mitsubishi Diaqueen GL5 rated LSD Gear Oil / straight 90 weight
On the other hand you have, you pick the brand I don't care....
Your brand, I'll say, Brand X GL5 rated LSD Gear Oil / straight 90 weight (Comparing Apples to Apples)
WHAT makes Diqueen SOOOOOO much better?
Not trying to be rude, but I as well as many others would like to know. Not much actual information on Diaqueen out on the net since it is exclusive to
. Many parts retailers, vendors, mechanics that I have talked to look at you with a stupid look on their face and say "Dia-wuhh, duhhhh, what's that".

Some of which had some of the same requirements as the Evo has. Never ran into a problem. The greatest thing you can do is start to run the oil you want that qualifies as a GL-4/GL-5 Hypoid (which both RP and RL are) and then after a change take a sample and have an analysis done on it. This can then tell you - Did the oil break down early? What is the metal break down of the parts being lubricated? Etc, Etc.
At this moment I'm using RP in the Evo - tranny, TC, and rear diff. The biggest things that any of these oils can offer is a little better protection and longer change intervals. If you track the car, then using something like this could very well help in oil break down due to heat buildup. (I use RL heavy shock-proof in the DSM TC and rear diff cause I beat it like a red headed step-child at the track)
yes, like i said, royal purple is the ONLY brand i could find meeting the evos 3 requirements-GL-5,90 weight, hypoid-redline, mobil 1, and the rest aren't straight 90 and will become too thin and could cause damage. 2nd gen transfer cases were very different from ours and didn't require straight 90 which is why a lot of the fluids people put in those caused problems in our cars. royal purple or diaqueen are the only logical choices to me.
I just think people are "hell-bent" on the proven crap that works. That being the Diaqueen fluid. Youve heard em, theyre in this thread, people who were buying new TCs and Diffs after trying other stuff. Is that proof technically... no but definitely likely, yes. I think thats enough for most people not to "try" the other stuff to save under $40. For the $50 the Diaqueen costs, Im sure its worth it to most that know they wont have to buy a $2400 part for using other fluids. So... just buy the Diaqueen and be happy. If you think the 1gallon, $50 can is too expensive, well then, ya shouldnt driving an EVO.
royal purple isn't being used to save money soon2BEVO, it's being used because it's a synthetic alternative to the stock fluid that will take more heat to break down and offer longer change intervals. 4 quarts of RP is only about 10 bucks cheaper than diaqueen, so money is not the issue being discussed in this thread.

Thats what I was responding to. Arent the stock intervals 30k miles? I do mine every 15k though.

Actually you don't want Synchromesh in the transfer case, Synchromesh gear oils lack the EP (extreme pressure) additives that protect ring & pinion gears from wearing out.
In the transfer case and rear differential you must use a GL-5 "Hypoid" type gear oil. The transfer case features hypoid gears to transmit that power to the drive shaft. The word hypoid is short for hyperboloid which refers to the design of these gears. All you need to know is that hypoid gears; don’t share a common axis, run quiet (for the most part) and they are a strong design. Yet by design the gear teeth must slide across one another during their meshing and this is why you must us a GL-5 Hypoid type gear oil in the transfer case and rear end, you need that slippery oil here. Use the wrong oil and the transfer case will start howling and growling within a couple tanks of gas. To make matters worse, the transfer case ring & pinion gears intersect quite a bit from one another and is called a high angle hypoid and these types of hypoids really need a lot of EP additives in the oil, which synchromesh oils do not possess enough of. The reason Mitsubishi chose a high angle is to tuck driveshaft up under the car for better ground clearance for that WRC stuff that they NEED to get their ***** back into again and soon.
Mitsubishi specifies the Diaqueen LSD Gear Oil in the transfer case and rear end of the EVOs. This oil is a single viscosity, 90 weight, and the part number is #377610.
If you can’t find this oil you must find a gear oil that meets the GL-5 Hypoid specification. Again this oil must ONLY meet GL-5 preferably 90 weight. Do not use a gear oil that claims to be GL-3, 4 & 5. These one size fits all type oils are not recommended and don't work any better than a one heat range fits all spark plug.
Also keep this in mind when you purchase an oil; multi viscosity index modifiers and dyes both reduce the film strength of the oil. They take up valuable parking spaces on the molecular level and that’s what the transfer case and rear end both need more of, film strength. Think of it as a scratch on a piece of glass, that's where it'll fail.
There are several brands of oil on the market and you can use any of them as long as it meets Mitsubishi's requirements and you change it often enough. I'd change it every 2500-5000 miles just to be safe.

i just did the research for you by going to redlines site, no single viscosity 90 gear oil available. your MTL or MT-90 are both 75-90(not single 90)and neither of them is GL-5 certified. royal purple maxgear 90 is the only option available, i've checked all the others before, mobil1, amsoil, motul, redline, etc. no doubt they make a quality oil, just not meeting the 3 requirements for our evolutions' transfer cases and rear ends.

Everyone has just made it seem that Diaqueen it the only oil that can be used in the transfer case, without catostrophic failure, in the entire world. Was just finding that hard to believe. That is why I brought up RP, Rl, Mobil......ect. These are in fact companys known for their place in the oil lubrication industry. All these companies do is manufacture quality oils, and you want to lead me to believe that they don't have an oil to go in the TC of the Evo. Don't get me wrong I love my Evo, a performance car, sure, but by comparison to others on the low side. As Jo & Joey stated earlier the Paganni Zonda a $325,000 car uses RP as factory fill. Not that I am going to rush out and go get some RP, just simply trying to inform myself and others that your TC won't blow up using another comparable oil. If another oil can do the "SAME JOB" as the Diaqueen and it's cheeper, I am all for that, but unlike others just not going to lie down and conform because Warrtalon says so. (The previous statement is in no way shape, form, or fashion meant to disrespect, slander, or otherwise defimate his character. Warrtalon is a very knowledgable individual and has even helped me. Was simply used as an example).....Kapeesh

It's heavier, but not a straight 90 weight. After checking out RL's website I don't see anything to back up what I thought I read on it being hypoid. I'll go home and look at the bottles again, because I could have sworn it said something different. I guess when you decide to use a gear oil for a peticular application you don't continually read the labels to see if the wording changed from when you read it before unless it says "New and improved" 
Then again I choose RP for the EVO because their MaxGear is all the above and I didn't plan on tracking the EVO like I do the DSM (the difference in using Heavy Shockproof in the diff and TC vs some of the lighter stuff).
Anyway, as I said I would - here is the conversation I had with David Canitz, the Tech Services Manager for RP. I also attached the pic of the Paganni for kicks!

Joseph,
For the 05 EVO - Manual TransAxle, Rear Differential, and Transfer Case - Royal Purple MaxGear 75W90
We offer a straight MaxGear 90 Wt, but the smallest container is a 5
gallon pail and this is more typical of what you would put into a off highway
heavy duty tractor. The MaxGear 75W90 is factory fill on a Paganni Zonda -
it will handle the horsepower and torque great.
> I see that the engine oil is warranty approved, but is all
> the gear oil as well??
Gear oils do not have an agency offering monitoring such as the API Engine Oil Licensing program. AGMA - American Gear Manufacturer's Association, ASME, API SAE set minimum standards by which lube manufacturer's build to.
In the case of Mitsubishi, Royal Purple does not have specific warranty approval (neither would 99% of lube manufacturer's) however, in reviewing the specifications as provided in the Owner's Manual that you supplied, the Royal Purple MaxGear 75W90 meets and exceeds the requirements as described by Mitsubishi (API GL-4 and GL-5).
Royal Purple stands behind it's products and will repair or replace equipment damaged directly by the failure of the lubricant in normal use and in the intended application. See the attached warranty statement.
I would like to add that this is not going to cover breakage of components due to 'racing' just as Mitsubishi is not going to cover components that fail due to 'racing' use.
> I want to know that if I used this
> would you guys stand behind the product if Mitsubishi
> decleared the oil was what caused the item to fail?? I know
> you'd want to do your own tests, I just want to be sure. The

> Evo is under a 100k mile engine and tranny warranty.
Again, if the failure of the part is due to the failure of the lubricant, Royal Purple will repair or replace the damaged components cause which are the direct result of the failure of the lubricant.
Let's be straight forward - oils do not work one day and fail the next. Lubricants fail due to contamination or applying the wrong type and grade of oil in the wrong application (using a motor oil in a rear differential for example). Failure due to contamination, lack of lubricant in the equipment, or mixing the wrong lubricant is not a failure of the lubricant.
In rereading my email I felt that the following would make you feel
good.
Attached is a picture of my Twin Turbo as well Mazda SCCA GT3 Track
Car.
I use MaxGear 75W90 in both the tranny's and differential on both
vehicles.
I've also attached a photo of me standing next to a PAGANNI Zonda In
Italy of which we are factory fill on the Cima 6 speed sequential transaxle
behind a v-12 Mercedes making 550 hp.
