Description
Redline MTL is a 75w80 synthetic has been the go-to fluid for Miata owners since the beginning. Smooth, accurate shifting due to the special additives for the synchros. It's what we use in most of our own cars.
Pure track cars should use MT-90 - it's not as happy when it's cold, but it will deal better with the high temperatures of the track. We also recommend the MT-90 for ND Miatas, as it is very close to the stock formulation.
For maximum gearbox protection on hard-driven track cars, mix in a quart of Shockproof gear oil.
NB 6-speeds require two quarts, all other Miata transmissions require three quarts (the third quart is used in the shift turret).
We can only ship Redline inside the US, for international orders please see your local distributor.

I replaced the fluid in my 5 speed as preventative maintenance. Out with the old and in with the new. The transmission feels just as good as it did.
Stopped valve tick. Worth the price
Please note that we generally do not recommend using Redline MTL in the engine as it is a GL-4 gear oil intended for transmissions. For more information about lifter tick, please see our video titled, 'What does that TICKING sound mean!?' on our YouTube channel.
Worked great for a 95’ NA, smooth shifting is awesome!
Perhaps it's unfair to give a poor rating to a product that's not even recommended by either manufacturer.
Both Mazda & Red Line recommend 75W90 GL-4 for the Mazdaspeed MX-5, and I'll be staying with MT-90.
My gearbox is much happier now that I've replaced the 'old' MTL with 'fresh' MT-90.
My experience is the opposite to that of Flyin' Miata.
I used this on my NB1 6-speed transmission for the past two years. My shifts felt ever-so-slightly better than whatever came out of the transmission, but nothing to write home about. This fluid will get the job done satisfactorily. I would trust this over whatever you can find in an auto parts store.
