Drove it over 300 miles this weekend, still shifting much better with the 10w30 than before. Zero grinding, shifts are noticeably less notchy, and there isn't any bearing noise in any gears. Not bad for having over 130k miles on it.

Not a big penzoil fan, but thier synchromesh gear oil saved my ax5.
I to don't buy using motor oil in a trans, no high pressure additives.

I am running AMS oil MTG. Equivalent or superior to Mt 90. Been great so far, shifts easier and I can pull heavy loads better because the downshift is easier. Still had to order it, none of the local dealers carried it. Imho I'm probably the poorest bastard on this site and I still sprung for the good stuff.

I second the MT90 advice...  Actually, even Jay Leno recommends it in the lates Popular Mechanics (or was it Popular Science?) for old cars, and he goes as far as calling it "Liquid Synchro" for how much of a difference it makes in old manual trannys!  By the way, my tranny was also shifting hard until I changed the oil to MT90.  Has been running fine ever since.

Actually he referred incorrectly to Amsoil MTL as a GL4 fluid in that article as being liquid synchro. MTG is the proper GL4. MTL is GL5 and that has the brass synchro killing additives. Unless they changed the article regionally for advertising puropses...

I was quoting the article from memory, but I have the digital version (Zinio); would have to check...

I ran the Royal Purple manual tranny fluid for a while and it caused a leak (at least thats who im blaming for the seal going bad lol) Ever since then I have ran Pennzoil Syncomesh. A lot of people swear by it and so do I. I have read the argument for running the 10-30w, but im a Pennzoil man anyways and I stick with what I know works...

Last oilshift on my tranny, I put in MT-90. Experienced rough shifting, trouble getting it in gear. When I exchanged it again a month ago, it was a darkish brown color, and a nasty smell... No brass residue, and the magnet was mostly clean.

Changed to Swepco 301, and the transmission is as new again. Smooth shifts, it feels like it runs better, I can hold higher gears in steep hills. Would absolutely reccomend that to others aswell. Kinda expensive, but worth it imo.

Do you mean 201? I couldn't find 301 on Swepco's website (looked because curious). Thats a GL5 rated fluid, which may (or may not) destroy your brass synchros.

Yes, of course I mean the 201. :P

Yep, I know it's rated at GL5, but from the papers I got from the salesman, it says it's yellow metal safe.

Cool good to know. I remember hearing endless bitching about trans fluid on the Rennlist (Porsche Forum). Swepco 201 was the favorite back then.

What does it cost a quart?

Online price is about 53$/gallon. Haven't searched much around for it.
Here in Norway there is only one dealer that sells it, for about twice the price... But everything is expensive here, so we'll just have to deal with it.

Could also recommend the Swepco 501 fuel improver. Can be used as an additive to the gas tank, or you can use it to clean out the intake and engine, like Seafoam. Just pour it slowly into the throttlebody or via an vacuum hose.
