Synthetic Gear Oil

Designed to provide the highest degree of protection and greatest efficiency for your drivetrain. Red Line provides a complete line of drivetrain lubricants which are optimized for differential, transmission or transaxle use over a wide range of temperatures. Proper selection depends upon the manufacturers' requirements and whether the application is for passenger automotive, commercial or racing use. Red Line Gear Oils contain polyol ester basestocks to provide excellent lubrication even under extreme conditions of high-loading and high- temperatures--their natural lubricity provide excellent slipperiness which reduces the sliding friction in hypoid gears to reduce wear and temperatures. The synthetic basestocks have a natural multigrade property, so large amounts of unstable thickeners are not required to manufacture our gear oils, which means that Red Line Gear Oils will provide a stable viscosity for even extended periods of use. Red Line also manufactures gear oils which can be used in limited-slip differentials without the use of additional friction modifiers.




MTL Gear Oil
  • Popular for BMW, Honda and Acura, Ford Focus, late-model Mini Cooper, Dodge & Jeep NV1500, NV3500 and NV5600 truck transmissions
  • Popular replacement for and improvement over GM Synchromesh® (#12345349) and Auto-Trak II® (#12378508), also Ford Motorcraft® XT-MT-QS
  • Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
  • Offers quicker shifts, 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

  • Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota
  • Offers quicker shifts, perfect synchronizer coefficient of friction
  • Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
  • High performance gear protection and longer synchro life
  • Eliminates notchy shifting, even when cold
  • Satisifies the gear oil viscosity requirements of 75W, 80W and motor oil viscosities of SAE 40, 10W40, and 15W40

  • Satisifies the gear oil viscosity requirements of 75W, 80W, 85W and motor oil viscosities of SAE 30 and 5W30
  • Safe for brass synchros, as it lacks the reactive sulphurs found in most GL-5 oils that cause damage
  • High performance gear protection and longer synchro life
  • Offers quicker shifts, perfect synchronizer coefficient of friction
  • Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota

Limited Slip Friction Modifier
  • Compatible with both petroleum and synthetic gear oils
  • Reduces break-in temps as much as 50°F
  • Add 1oz at a time to clutch-type limited slip or posi-traction units to eliminate chatter

More info Limited Slip Friction Modifier

80W140 Gear Oil
  • Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360
  • Contains additional friction modifiers for suitablity with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required
  • This product is not designed for use in manual transmission or transaxles with synchronizers, as its slipperiness may lead to shifting problems
  • Popular in stock car racing differentials and transmissions
