This is the Red Line MTL 75W80 GL-4 Gear Oil. This is a fully synthetic GL-4 rated gear oil that contains major formulas that add extra protection against friction, while promoting better shifts. 



  • Popular for BMW, Honda and Acura, Ford Focus, late-model Mini Cooper, Land Rover/Range Rover LT77S, Dodge & Jeep NV1500, NV3500, and NV5600 truck transmissions
  • Popular replacement and improvement over Gm Synchromesh (# 12345349), Auto-Trak II (12378508), and Chrysler spec MS9224
  • Safe for brass synchros as it lacks the reactive sulfurs found in most GL-5 oils that can cause damage
  • Offers quicker shifts and has a perfect synchronizer coefficient of friction
  • Eliminates notchy shifting even when cold
  • High-performance gear protection and longer synchro life
  • Satisfies the gear oil viscosity requirements of 75W, 80W, and motor oil viscosities of SAE 30, 10W30 and 5W30
  • Recommended for GL-1, GL-3, and GL-4 applications as well as where most special synchromesh fluids are specified  
  • Appropriate coefficient of friction for most manual transmission synchronizer (other's synthetic gear oils are often too slippery for proper synchro engagement
  • Works well for both high-mile and low-mile transmissions
