rweddy Posted July 29, 2004 Share Posted July 29, 2004 Ok I know this point has been discussed before. But I need a good single thread consensus. I am getting ready to change mine and I am trying to decide what to run. I was told by redline to use 75W90NS, not MT-90. I have heard great thinks about Catrol something, but we cannot get this in the united states correct? Does anyone have any insight for me?? Thanks Quote Link to comment Share on other sites More sharing options...
Guest jclay Posted July 29, 2004 Share Posted July 29, 2004 Castrol TAF-X, Setright swears by it. I think someone found it here in the states under a different name. A search for the thread "Redline MT 90?" should fill you in. Quote Link to comment Share on other sites More sharing options...
Guest jclay Posted July 29, 2004 Share Posted July 29, 2004 Woops, i was wrong, thats not the right thread, buts its here somewhere. Hopefully someone else will chime in. Quote Link to comment Share on other sites More sharing options...
Setright Posted July 30, 2004 Share Posted July 30, 2004 Okay, okay! So, I really like Castrol TAF-X :-) Statside, it's called "Syntorq". Just to refresh, I have tried RedlineNS, and it's not the worst for actual quality, but it breaks down way too fast. Castrol TAF/Syntorq has improved with age.

DerFahrer Posted July 30, 2004 Share Posted July 30, 2004 Again, I've had best experiences with the cheapest, junkiest gear oil I can get. The cheaper, the better... Quote Link to comment Share on other sites More sharing options...

Just to refresh, I have tried RedlineNS, and it's not the worst for actual quality, but it breaks down way too fast. Castrol TAF/Syntorq has improved with age. Ok got this info Syntorq LT SAE 75W-85, API GL -4 is a premium high performance, synthetic gear lubricant for synchronized manual transmissions. Syntorq LT is available through General Motors (Part #12346190) and Chrysler (Part #4637579) dealerships. Please contact your local dealership." So Syntorq is still not the correct spec for a AWD Subaru Transmission. Subaru calls for GL-5. I was told that running GL-4 in your AWD Subaru tranny will hurt the front differential. If I was going to run GL-4 I would get Redline MT-90 which is same specs as the Syntorq and readily available, and works great in all manual transmissions that I have run it in. Back to square one!

Setright Posted July 31, 2004 Share Posted July 31, 2004 The specs on TAF-X say GL4 / 5 Quote Link to comment Share on other sites More sharing options...

SevenSisters Posted July 31, 2004 Share Posted July 31, 2004 Hey folks, How do you know what's good? Published specs? Sound of tranny? I try to stick with a brand name when buying lubricants but I have no clue how to gauge how something like this performs. Do you have an oil analysis done?

Setright Posted August 1, 2004 Share Posted August 1, 2004 Mainly based on feel. SOund too. TAF-X allows quickish shifts without KERR-unch! Quote Link to comment Share on other sites More sharing options...
rweddy Posted August 2, 2004 Author Share Posted August 2, 2004 Mainly based on feel. SOund too. TAF-X allows quickish shifts without KERR-unch! Well after much research I found out that TAF-X, (Syntorq here in the states) is GL-4. So after reading so much good about it from Setright I was going to run it but I could not stomach the $130.00 it would cost. ($30 per quart plus tax) So I have had very good luck on other vehicles with Redline MT-90 which is a GL4 tranny fluid. I put some in on Saturday and have driven well over 200 miles since then and it is awesome!! Plus it is only $7 per quart!!! Finally crunch less up and downshifts in my wagon!!!

Setright Posted August 2, 2004 Share Posted August 2, 2004 As you wish captain, as you wish. :-) It set me back about $100, including tax. Redline would cost the same, since it's a rare product over here. Quote Link to comment Share on other sites More sharing options...
