My apologies. I got distracted
For the record, I change mine @ 7500 miles to keep things silky smooth

Interested.
I'd be REALLY interested if you could get Castrol Syntrans.
The limited specs available are superior to the Syntorq. Looks like a really good 75W/85.

That may be true, but I can't vouch for something based on specs listed on a piece of paper. It may be better...who knows. I do know that the LT is specifically formulated to combat heat. I don't know enough on the SynTrans to comment.
How clean the oil stays is directly related to how much torque the engine makes and how often the torque is used.
You havent given me any reason to say this oil is doing a good job. So you drove your stock 9 65,000 highway miles without an oil change? thats what I am getting here....

His interval was 8000 miles according to the report. I believe he's mentioned in the past he changes this tranny fluid every 7-8k. He's also stated he does not track the car.

First off, I had 2nd gear notchiness/grind with the OEM Super DiaQueen. It was annoying. At around 10-12,000 miles I switched over to the MOPAR fluid. 2nd gear grind magically disappears.
I purchased my Evo 8 MR in May of '05. In July of that same year it was modified and put down 306whp on a DynoJet. In June '07, I had additional mods put on my car including the EvoGreen. Put down 333whp on 91 and 363 on 100 on a Mustang Dyno.
I change the tranny fluid every 7500 miles or so because of the issues with the 6 speed and the extra heat the unit generates. At 68,000 miles I had an oil analysis done, and the tranny seemed to be wearing really well (hence the last sentence in the report from Blackstone).
I now have 85,000 miles on my original 6 speed. This fluid helps with the notchiness, and the evidence seems to support the idea that it's easy on the MR transmission. Unlike some people who put in mystery oil x and say "it feels good" I have provided longer term data.
What else would you like to see?

I'm definately interested... the mopar stuff is kinda pricey (like the OEM diaqueen). After changing it to the mopar oil, the tranny does seem to shift smoother. I've been running it for about 5k miles now. The only thing I've noticed is it takes slightly longer to warm up than the OEM oil, and can be notchy in the cold. Once it is warmed up it feels great and buttery smooth. The 1-2 shift is pretty notchy when cold.
I called a buddy up to see if he had any interest in some of this tranny oil. He says "Why, the oem stuff is what Mitsu calls for and they warranty the tranny for 100k so i'm sure there is nothing 'better'." "Plus if you read the owners manual it states that when the trans is cold you will notice 'notchy' shifting untill it reaches normal operating temp, this is normal and will not cause any harm to the trans"
I went on to tell him that Mitsu based all that on a car with no mods and 'normal driving' of which almost no Evo owner has or does, lol. Plus, the oem stuff is not full synthetic which means it's viscosity changes with the temps and anything outside this temp range is not good for the tranny. Such as sub zero cold starts and or driving the car hard enough to heat it out of it's primary operating range.
The Mopar stuff was made for a Dodge Viper of wich produces far more the torq sheer and heat on a tranny as would a 300hp Evo. Hence the need for a oil that will stand up to it. Full synthetic is the choice since it is a made and engineared to be better than mother natures own recipe. Not to say if it's good enough for a Viper it's good enough for my Evo. Rather, it's the 'same stuff' only engineered to be better.
He says "Mitsu engineers already took these things into account". I say, for the price they charge for the oem fluid, the profit margin alone will pay for the 10% of failed 6 speeds they actually warrany
Anyway he's not interested
Sorry for the big useless post, it's simply the reason I am willing to try this stuff. The data provided from a car used much like mine helps as well

Oh, can you post the tech data on the Mopar oil, like GL rating ect?
