Gearbox oil recommendation?
#71
the honda mtf and mtf 3 viskosity in cst at 40°c and 100°c are:
mtf: 50,8 - 7,5
mtf3: 32,5 - 7,2
source: google search, oil analysis on bob is the oil guy and so on. you could do you own search.
these viskosity values are handy when you search for a alternative for the honda mtf. you could compare the honda mtf values with datasheets from oil manufacturers.
and yes, honda mtf is in the 75w-80 range. the mtf 3 is more in the 75w range.

For grins I looked up the maintenance schedule for the gearbox. Had to use the 2005 owners manual 'cuz there's no schedule in my 2006 manual, it's all in the Maintenance Minder.
Replace manual transmission fluid. Every 120,000miles (192,000 km) or every 6 years, whichever comes first. Honda expects their MTF to last quite a while! Anyone run theirs that long? (Severe service would be half that.) I have no scientific data indicating my gearbox shifts better or even differently from whatever oil the prior owner had in it in 2014 to the Honda MTF I put in the next spring to the Royal Purple SyncroMax in there now. A lot of this stuff is perception -- we expect the gearbox to be smoother with an oil change. And since I just rolled the odometer over 60,000 I'm sure the oil change has met specs.
Just a line below it on the same page: Replace rear differential fluid. Every 30,000miles (48,000 km) or every 2 years, whichever comes first. The differential is the one to be concerned with as to wear. I'll be changing this next month along with the engine oil. Gearbox is a game time decision but since I'm under the car and oil is cheap...

@ simons: Technical Information -> Data Bulletin -> Open PDF

The value for the synchromesh is 49.4 - 10.4. Compared with the Honda MTF, it´s the same when cold, but a little bit thicker when hot. Thats generally considerd as better for wear protetction.
@ zeroptzero: Thanks, i dont know that you dont have MTF 3 in the USA. But, being a international forum with members from all arund the world, it is maybe helpfull for others.
Do you have the values for the Honda MTF 2 ?

mtf3: 32,5 - 7,2
So actually, the Honda mtf3 is much thinner when cold than the Amsoil. Amsoil 49,4 @40C vs mtf3 33,5.
Makes me wonder why people report smoother shifting when cold compared to Honda mtf. Not sure which version those people of mtf had used? As was posted that the mtf had become thinner when cold then early mtf formula.
Now wondering again if I should get the MTF3 or Amsoil!?

With so many positiv reports in all Honda Forums, i would not overthink it and just give the Amsoil a try. If you live in Europe, i would recomend you to try the Ravenol MTF II 75w-80.
In my personal opinion, the viscositiy is important for the feeling when the oil is cold, after the start. But it´s also the additive package and Oil qualitiy that makes a difference in shift feeling when the oil is hot.

with amsoil, i've honestly never felt it become not smooth. so i changed when i felt it had been a long time or many miles, around 2 years or 20,000 miles.
that's why i recommend the amsoil mtf so much, it lasts a long time as far as the smooth when new feeling.

Whatever fluid you use, change it frequently. Once a year minimum.
