If you have a manual transmission and are looking for a dedicated MTF, you know they are impossible to find in the US! This has also been my biggest fear of buying a non-Honda manual transmission since I found out that you can't/shouldn't use GL5 in them.
Some manual transmissions can use ATF, and Hondas can use motor oil, but everyone else is out of luck when looking for a suitable MTF. The Pennzoil and Valvoline Synchromesh products are really only suitable for the exceptions I mentioned (Hondas using motor oil, and cars where ATF is spec'd). They are too thin for most other manuals.
GL5 gear oils, the ones that stores actually carry, is not for use in most transmissions.
Napa carries Liqui-Moly #20012, but some people don't like LM, and not all Napas stock it (but they should be able to get it upon request). Castrol is a more reputable brand that people like.
I ordered a bottle of cheap UltraLub 75w90 GL-4, but it has not arrived yet. I will send it out for a VOA when I receive it.
Supposedly, Pennzoil makes a 75w90 GL4, but it isn't available in US stores even though Pennzoil/SOPUS says it is. Napa has it in Canada, but not the US. Sometimes you see it on eBay for $20-30/qt
Castrol does not sell their Syntrans line of manual transmission fluids in the US, but thanks to the Amazon Global store, they are finally available to US customers. The Amazon Global Store has the following Castrol Syntrans in stock:
Castrol Syntrans V FE 75w80 (Group C on MolaKule's list)
Castrol Syntrans Multivehicle 75w90 (Group G)
Castrol Syntrans Transaxle 75w90 (also Group G)
What dedicated MTF do you like to use in your manual transmission calling for 75w90 GL4? I don't have a manual transmission, but knowing Amazon has Castrol MTF from the Global Store certainly helps a lot. The Ultra Lub might be good pending the VOA.
