The products in question today are the GL-4 & GL-5 gear lubes from AMSOIL, one of the leading manufacturers in the synthetics oil industry here in the United States.
I was approaching 30k miles on my 2006 Mitsubishi lancer Evolution and was aware of the maintenance it needed for upkeep. The trans/transfer case/rear diff fluids were due for a change. I searched countless internet evolution sites looking for the best oils to use on the car. Some suggested synthetic lubes, some suggested conventional oil, but there really wasn't any rule of thumb or predominantly accepted fluids to use, just more of a preference or opinions based on what others used, and their pleasant or horrific stories of their outcomes. After reading all these reviews, I really didn't read anything bad upon amsoil gearlubes; they weren't really a majority in the users' preference, but upon use, nobody complained. So, I decided to give it a try.
An order was placed for 3 quarts of Amsoil API GL-4 75W-90 (weight specs as recommended per Mitsubishi) Manual transmission fluid and 2 quarts of AMSOIL 75W-90 Severe gear API GL-5 for the transfer case & rear end, both synthetic of course.


Being synthetic, the oils poured in almost like water, which made the job alot easier compared to conventional gear lubes being almost as thick as fudge; they were so thin that I almost became skeptical if this could actually be good for the car, but the oils being thinner would mean they provide less resistance for the gears to rotate (anyones who's been to an autoparts store and played around with those Lucas Oil oil stabilizer demo gear contraptions will get the idea.
Upon startup, just putting the car in reverse to get it out of the garage was alot smoother in comparison to what was in there before (most likely the Mitsu Diaqueen fluid). On the first ride down the block, the gear changes seemed somewhat smoother as well. There are no extra noises and no ruined parts so far, as its been 800 miles. Id gives these lubes from AMSOIL a big thumbs up for anyone wanting to use them in their car's manual transmission/transfer case/rear differential. In fact, the same combo was performed on a buddies 2G eclipse, with similar results.
PS: For those of you that don't believe that evo owners work on their own cars anymore:
