Greater protection for hard-working gearboxes.

Made in the USA

Availability: In stock



Redline MT-90 is a great gearbox lubricant for 'boxes that have to work hard. It's not the best choice for street cars because it needs to be up to full temperature to work properly, but if you're doing a lot of track work or need a little more protection for your gearbox it's the one to choose. 

Recommended for street and track driven NDs. For street NA/NB/NC cars we recommend MTL.

NB 6-speeds require two quarts, all other Miata transmissions require three quarts.

This is the oil that Red Line recommends for a Miata 5 speed box.
The oil that Red Line recommends, on their website, for our gear boxes is MT-90 75W90 GL-4 gear oil. Our gear boxes were designed for convention (non-synthetic oils) and the clearances are relatively large, larger than for a modern box. A correspondingly heavier oil works well in our boxes, especially for severe applications and boosted cars.
