EVO IX MR 155,000 mile maintenance
Thats alot of driving! good thing to know these cars are lasting that long.. and as previously stated... A tune wouldnt be a horrible idea.. I understand the whole never having time for it.. But something so simple as the boost controller and the tune will make night and day difference on your car. Not to mention depending on the tuner, can make the car even more reliable!!!

it's on the "to do" list lol i actually plan to finish off the exhaust with a dp, high flow cat, and 02 housing, then get the thing tuned. just haven't had the time. too many other things going on. i just finally got the thing in and out of the shop to have some needed paint work and body work done after i went back to stock hood/trunk, and replaced my beat up Ralliart front lip.
I used OEM Diaqueen for the TC and rear diff, and Mopar 75w-85 GL-4 fully synthetic transmission fluid for the tranny. I had Amsoil 75w-90 GL-4 fluid in the tranny from the last change, but that always scared me because it's not an EXACT equivalent. I found the Mopar stuff at a local dealership, which was nice because I always had to order the Amsoil, or OEM Diaqueen fluids. Now when I need to do work at home, I can just run down the street, and this stuff is exactly the same as the Diaqueen, only synthetic. I can't tell if it's just in my head, but the transmission seems smoother with the switch.

This is why I prefer the Castrol Syntorq LT (what the MOPAR stuff really is). I've had great results.
P.S. 122,000 miles and counting.

I was pretty sure it wasn't just in my head, because i've read other threads from people who had the same experience lol that reminds me, I'll be contacting you guys very soon about a set of throttle body shaft seals
I may need to get some of this stuff. So, would it be okay to mix with the OEM fluid if I have some of that left since it's comparable? Sorry for the off topic.

I don't think he wants to do a cocktail of it. I think that he wants to drain the current fluid and then pour this stuff in. What he's concerned about is the residual fluid left over in the transmission mixing with the Castrol when he pours it in. If that's the case, you'll be fine.
