Product Details

Red Line MT-90 is a 75W90 GL-4 synthetic manual transmission gear oil for manual transmissions and transaxles. It is slightly heavier than Red Line MTL and protects gears and synchronizers. Its balanced slipperiness gives a coefficient of friction that allows easier shifting. Red Line lists it as most popular in Nissan, Toyota and Mazda manual transmissions and transaxles, as well as other selected applications. This listing is for a 1 gallon container.

Key Features:

  • 75W90 viscosity with a GL-4 rating
  • Synthetic base oils with a very high viscosity index, so viscosity stays relatively constant as temperature changes
  • Wide viscosity range allows proper shifting over the entire temperature range the transmission will experience
  • Good shiftability and synchro compatibility
  • Extra gear protection and easier shifting
  • Excellent shear stability and oxidation stability, so its physical characteristics change little with use

MT-90 is a thicker 75W90 version of Red Line MTL, which behaves as a low 70W at very low temperatures and a high 80W, nearly an 85W, at elevated temperatures. That viscosity helps prevent wear and deaden gear noise.

This is great stuff. I recently had my clutch replaced and afterwards, shifting gears felt all sludgy and like a constant battle. I figured they probably had used some less than optimal gear oil (and they couldn't tell me exactly what oil or weight when I called to ask about it). I did some research and got this, and it's really made a difference. I have yet to drive it in winter, but so far I'm really happy!

Fast and easy to get the part I wanted. The lights look incredible and were incredibly easy to install.

All was good with order

Best price. Website is easy to navigate, and tye check out process was quick and easy.

Nice place to shop

The service is great. Wiper refills ordered for my Nissan Leaf did not fit, even though the website listing said they would. I was provided a refund over the phone without having to return the products. So, product listing--1 star; service--5 star

Quick shipping on my order. Thanks

best price I could find...just ordered the product. Hope everything else is as good.

Great prices and item shipped quick!

Good prices and quick shipping. Thanks!
