Are you using this stuff yourself? 1 or 2 tubes in the gearbox? You use it in the diff as well? What exactly is your experience with this and its effects? And which base oil did you use in the gearbox while you added this? Does it change anything to cold shifting?

HAH!
Gentlemen, i was completly wrong! Thanks for correcting and enlighting me!
Wonderfull Forum!


But one little thing: I tested the orignal Honda MTF vs. the Ravenol MTF II, i found that the Ravenol works much better. Maybe interesting for European S2000 owners.

Only at the gearbox, not in the Torsen diff that partly relies on friction.

I bouhgt my S2000 and the transmission was notchy beyond belief. Like a farm vehicle. The 3. gear especially somtimes gives a "blowback" when putting the gear in like firing a 9mm pistol.
ASAP i changed the gearoil to the Ravenol MTF II, that i found much better to the original Honda MTF in my former car, a Honda del Sol.
As expected, this makes things much better, but it was still a little bit notchy.
I go on and added one tube of the Liquy Moly gear additive and this was the finall step so to say, now the shifts are perfectly smooth.
If you think about it, It is crazy to add some MoS² stuff to a gerbaox that relies on friction at the synchro rings for proper function, but it really works.

The "ceratec" additive from Liquy moly should also work, but it´s much more expensiv.

@ ragtophardtop: Thanks. I know that redline makes extremly high quality oils, but they are the most expensive oils you can buy here in germany.
Roughly 30.5 US $ / Quart.

Schaltgetriebeöle Auto - RED LINE Synthetic Öle und Additive

I am not cheap on oil, but.......
but....
maybe i give it a try one day.

I often use the car for very spirited drives cross country and sometimens, not often, beat it over the Autobahn. The S2000 is not build for this, but it´s fun sometimes.

Im not saying other fluids are worse, and sure there may even be something better.
@Billman250 , can you share what exactly would be masking something? Do you mean an additive, or a thicker fluid for the transmission? As I posted, I use redline MTL 75w80 GL 4. I changed out what I believe was the original fill at 50k miles. I'd like to understand if something like this is what you indicate will smooth the oil teeth off the synchros and make shifting worse.
