Red Line Synthetic Oil

MT-LV 70W/75W GL-4 - QUART

• Popular in Toyota/Lexus LF 75W, BMW X-Drive and other transfer cases transfer cases calling for Shell TF0870
• Recommended for Mercedes 235.10, Dodge/Fiat BOT 350 M3, GM BOT 303 mod, Toyota/Scion Manual Transmissions Gear Oil LV, VW/Audi and BOT270A Graziano Transaxle for Aston Martin, Audi & Lamborghini.
• Offers quicker shifts, a 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
• Low fluid friction to improve power transfer
• Satisfies the gear oil viscosity requirements of 70W & 75W
• Recommended for GL-1, GL-3 and GL-4 applications as well as where most special synchromesh fluids are specified

• Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection

  • Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
  • Red Line offers lubricants to pinpoint nearly every transmission application
  • MT-LV, MTL, MT-85 & MT-90 are not for use in differentials with hypoid gears
  • Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates

  75W140NS GL-5 GEAR OIL - QUART

  • Contains extreme pressure additives like our 75W140 GL-5 oil, but lacks friction modifiers to balance slipperiness
  • Popular for historic and vintage transmissions, like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks
  • Helps with noisy or rough shifting in troubled A-833 Dodge/Plymouth 4-speed transmissions from 1964 to 1969
  • Option for noisy transmissions when mixed with 75W90NS or MT-90 to bring viscosity level up
  • Also used in clutch-type limited slip differentials in racing for maximum lock up-some users add Limited Slip Friction Modifier in small doses to customize slippage
  • Non corrosive formula, safe for use with all synchro materials

   
  

  These products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers (except NS) for proper limited-slip operation

  • Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
  • Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
  • High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
  • Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
  • Exceed API GL-5 specifications
  • Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
