I too agree that syncromesh does not belong in the mix and had suspicions of it here: http://www.clubwrx.net/forums/2193716-post53.html . That is why what I ended up running was a 2 oil blend, refer to the first post.

I'm also in this camp. I really don't see the syncromesh doing any good in that mix. Much different viscosity than the rest of the parts.

Pavia, I saw your ill fated story half way through your post. Sorry.

I'm also glad you got the Extra-S in there. That should be great fluid for a street driven car.

That should be great fluid for a street driven car.

the beauty of it is many guys racing the Impreza are also using the same fluid

Part A: well put my Mix of 1.7 Q Redline NS and 2 Q of Lightweight shockproof in at about 39K and I am at almost 57K now.

Still working pretty well and getting close to the 20 K point. Dub you still having success with yours or did you switch out to another fluid?

Next up may try the Amsoil instead of the Redline NS.

How many K on your mix Jeremy?

Part B: This goes for those posting and not wanting to read the thread. Insights from this thread are as follows.

If you want ONE FLUID: Subaru extra S is your oil....either buy a 5 gallon jug at cheap cost or go to NASIOC thread that has it at 20 bucks a quart.

If you want an effective TWO FLUID mix: USE TWO Q Redline LIGHTWEIGHT shockproof.....and EITHER 1.7 Q Redline 75W90 NS OR 1.7 Q Amsoil 75W90 SVG

(Please note I am no specialist or saying use one or the other....all cars and trannys and drivers and locations are different...try it, if you dont like it try another)

How many K on your mix Jeremy?

About 15k and I am happy as a clam still. I am thinking about swapping out the amsoil mix in the spring for the straight Extra S just for the science of the whole issue and blackstone results.

[Pavia]

Forgot to mention the status of my drain plug when I swapped the USC out...

Well, nothing major. No chunks like I've seen in other forums. Basically, a small amount of blackish-grey residue on the end of the magnetic plug. I attribute this to a mixture of sludge and fine metal particles. Just enough to cover the tip of your finger...

So that's after 9k on USC. I recall it being similiar on 10k of factory fill.

[Big Sky WRX]

^ that's what I typically see regardless of fluid

[DUB]

Dub you still having success with yours or did you switch out to another fluid?

I only have about 5-6k on it so I can't speak of it's longevity. But I can say I have driven around in temps approaching 0 and it has shifted just fine. I'm still very happy with the mix.

Before anyone runs or continues to run any blend that involves the synchromesh or any variant of Uncle Scotty's ****tail, I STRONLY encourage you to over to NASIOC and check out the latest findings. The short story is the UOAs are coming back scary and the two best Subie tranny builders in the US are talking about damage because of the ****tail.

Link? I'm doing a bit of searching on Nasioc but haven't found this yet

I own a 2003 WRX (stock).

I measured my gear box oil level the other day and found out that is missing some, since I was on a hurry I couldn't get Redline, which was my intention, so I ended up buying Lucas Heavy Duty 80W/90 to fill up my gear box. I haven't added it yet, since I don't use the car very much yet.

Do you guys think it will be okay adding/mixing that Lucas Quart with the oil that the box has currently?

Is not synthetic, however, is heavy duty.

Should I add it or wait and buy Redline's?

Adding the Lucas oil won't hurt anything. Overfilling your tranny way past the top mark will. If it needs just a bit go ahead.

Also make sure you were on level ground when you discovered it was low. Even a standard driveway incline can give a false reading.

Hey Jeremy you working with anyone over at Blackstone with your oil analysis if you're doing it?

My tranny has the lightweight and Redline NS mix in it with just over 20 K on it. I was going to change it out and try the Amsoil SVG mix but wanted to send some of my old fluid mix in for analysis as well as a new mixed up sample of the LW NS mix for comparison.

Might make sense to work together with blackstone and combine all the data.

I haven't changed this mix out yet. I plan on it in a month or so, then I'll send it in.

i have ppg straight cut gears and i the oil on my tranny is like real light blue does anybody knows the name of the oil thanks .

[Big Sky WRX]

lightweight ShockProof (by Redline)- good stuff

[Pavia]

How is the noise level with the ppg's? Is it something you can get used to on a daily drive?

Also, what clutch did you go with?

I think I'm going to stick with Subaru S when I get the new gears this summer.
