By the way, right now I am deciding what oil to use in my freshly rebuild gearbox. That's why I read several forums about grinding and oil. As I said, no matter what brand, you must use light viscosity. My impression is:
  • Amsoil Synchromesh - good for short time, not very much miles later it is the same as old oil.
  • Redline - good for long time
  • Honda MTF 3 - just quite many loyal users, because it's very cheap (For example I get 2 liters for £10-12)
Then I separated posts from gearbox builders. They recommended:
  • Honda MTF 3 - strictly for daily drive
  • Torco MTF - daily drive
  • Torco RTF - racing
Anyone tried Redline or Torco? :)

And a OT question: will 2 liter be enough for freshly rebuild box? If I decide to buy not Honda MTF, I don't know to take 2 or 3 bottles...

Can't remember what I used but it certainly helped as said though its your reverse synchro causing the issue

Hmmm I did wonder that. Is that something Kawa can sort? Maybe have a reset button, but otherwise allow the existing votes to remain if the OP is edited?
Bah - it looks like this is a feature they're still working on. There's no neat way to hack it in at present :x

I have never read anything bad about Amsoil :? I have it in both my Ludes and have done for years. They take a beating on track and are both over 200bhp (just). I have never had anything other than silky smooth gear changes. Im sure that I read the specs of the oil and it exceeds the Honda spec.

2 quarts will be enough.

Hmm.. Again don't know what to choose better :)

Here's one of those threads. Of course you must decide yourself what is true, but maybe it will help:

Having spent ages reading up - I have elected to try the Torco MTF. I will report findings back here once it's in the box :)

i would have thought different oils would preform differently in different gearboxes with varying amounts of wear, for instance - new gearbox with oil x would prob get different results from an older box (with some wear) with same oil.
maybe

Who knows as there isnt any way of quantifying the feeling of a gear change. If its smooth, its all good :D

I suppose the major differences in how it feels would come from when the oil is cold (driving from startup) or extremely hot (hooning it on track).

Well, I think I can safely say...no!

3rd gear vtec to 5th.....crrrrrrrrk! But, and this a big old but, the general day to day gear changes are now superbly smooth! 8-)

So for that alone I'm glad I used it. Better than any other ? No idea :lol: and Type-S bods - you need 2.2 US qts ;)
