The perfect transmission oil
+1 amsoil MTG works great in my 6-speed edm evo ix. A lot of people start to use it in Europe. It is hard to find a 75w-90 or 75w 85 in gl-4 api. Everything is gl 5 and everyone thinks that gl5 is much better than gl4. When they use gl5 in the tranny and the grinding starts, then they try to find gl4. OEM fluids are NOT available European countries so we must use other brands.
For the 6 speed (I know I sound like a broken record) the Castrol Syntorq LT is a GL-4. A lot of guys on Lancer Register use the Castrol, which is how some people on EvoM found out about it.
I use to run royal purple. It was good for a little bit. Once I got close to a thousand miles the fluid took a walk. Im guessing its more for racing purposes not for DD. I am using valvoline synthetic tranny fluid and its working great(it was what my napa had on hand)
Seems with all the TC 's failing a heavier shockproof oil would add the best protection to our fragile units.
All whoever, whenever says what... people have been getting stellar results from the Amsoil. I'm not willing to do the search right now, but the reports from Blackstone and other's analysis look better than "others".
I run it myself, and have to say it's worth it. I'd always been an advocate of running the super thin Synchromesh and changing it every 3k when I changed my engine oil (due to shear down). However, with the Amsoil, you get the same slick action, with much greater service intervals. All in all, it's my favorite not because jack knob A, or jack knob B says it's good stuff, but because the lab reports and my own personal experience say so. Also helps that my local retailer gives me the hook up at just under $10 a quart

35 years ago, that was always the answer... "Heavier oil gives better protection"
That is not true anymore and, as seen, dies a hard death to dispell that notion.
You need to run a fluid that has a high film strength and the lightest viscosity you can get away with.
Take a look at the following Link and see where Gear Lubes really are. Note the Viscosities on some where they started a lot higher in Viscosity than the label claimed and sheared out of grade. It is the additives that do the work, not the base stock.

Most people don't know that a 75W-90 is equivalent to a 20W-50 motor oil at operating temp (212 Degrees F) because it is so heavy when cold or at room temp, But the additives are totally different to to the environment they are used.
