hi all,
i have a 1.5way in the rear of my gtr which i recently purchased - with its common clunky & shuttering noises when taking sharp turns at lower speed, the noise is bordering embarrassment lol
anyway, i dropped the old oil & bought tomei diff oil 80/90w which was $100 for 2 ltrs...this product is incredible
the inherent noise of these mechanical diffs is completely eliminated & actually sounds like a factory viscous
i did the same thing to my old nismo 1.5way 2yrs ago & ran this oil - if you have a noisy mechanical diff, you gotta buy this oil!!!
i hope others benefit from this thread
