Gearbox oil: Redline MTL vs. Rdline MT-90?

[gordanfish]

Hey guys,

I appreciate all the great info on this website. I am currently considering changing my gearbox oil on my 2001 Yaris 1.0. I read on another website the following, and was wondring if you guys had an opinion on which might be better for my older Yaris? Thoughts? Comments? Opinions?

"Redline gear oil is friction-modified to give better synchro engagement and so should give a useful improvement in change quality. For your car you should use Redline MTL (as opposed to MT). It am not a great fan of using Dexron ATF in gearboxes - it has a lower viscosity than the 75W-90 but is more "slippery" and will give a slower synchro lock-up. If you want to use an ATF then you should use a 'Type A Suffix A' oil like Mobil ATF200, Castrol Agri-ATF or Elf Trans-O-Matic. - these will provide better synchro action.

Other good gear oils include Castrol SMS-X and Motul 75W-90 - both of these will give a fast gearchange. SMS-X is particularly good in cold weather since it has a lower viscosity coefficient.

MTL is a good place to start though and costs about £10 a quart - try it and let us know...."
