I wouldn't put any GL-5 rated fluid in the tranny, even if it's dually rated GL-4. Not guarenteed to be yellow metal safe and can damage the syncros. Some people have used GL-5 fluids with brass synchros with no issues, but it's not worth the risk to me.

As for differential fluid you have more flexibility. Anything that meets honda specs should be fine. However I would be wary of the competition fluid if you plan to drive your car much on the street. The competition fluid may require more frequent changes than a more streetable fluid. The competition fluid may protect 'better' but may not last as long.

 

I can change it, I need a good track oil, and also a good street oil

 

If you want a good track oil try NEO synthetic. They're located in Signal Hill. A lot of professional teams in Japan and europe use their oils. If you call baker precision ask for Hung he'll help you out.

thanks for the info... I have heard of them as well.

 

Motul oil's are superb. Myself and a number of highish BHP Impreza guys use them.

Smells like bubble gum

In the Honda I use 5W40 V300 oil, but we have colder climates in the UK than most in the US.

Not sure on the gear oil as I use Silkolene in that.

All of those weights are too heavy to work properly in the transmission right? But in the diff., they will work well.

 

make sure you use ONLY GL-5 rated fluid in the diff

 

which one would you reccomend? Have to tell them which one I want to use, I have no clue on the diff fluid which one is good?
Thanks

BTW it is also safe for yellow metals
