Brand: Red Line Synthetic Oil

RedLine Gear Oils protect gears under much higher temperatures than any petroleum oil can. They can even reduce differential temperatures by 10 to 70 degrees Fahrenheit, while improving driveline efficiency.

  • 75W85 Gear Oil (formerly LightWeight) is light enough to reduce frictional power losses in racing or street differentials. It is not recommended for synchro transmissions due to extreme slipperiness. Meets GL-5 specifications. 75W85 is suitable for use in FF1600 and FF2000 dog-ring transaxles.
  • 75W90 Gear Oil is recommended for most street and racing differentials including limited-slip units. Contains friction modifiers for smooth operation of limited-slip differentials. It is not recommended for synchro transmissions due to extreme slipperiness. Meets GL-5+ and GL-6 protection ratings. Replaces BMW SAF-XO and SAFX-LS differential fluids for non-LSD.
  • 75W110 Gear Oil is a new intermediate viscosity offering better film strength and noise reduction compared to 75W90 without the increased drag of 75W140. Developed on the racetrack, but also popular in light trucks. Meets GL-5+ specifications. Not recommended for synchro transmissions due to extreme slipperiness. Suitable for clutch-type LSD.
  • 75W140 Gear Oil is an excellent all-weather gear oil for cars and light trucks. It is not recommended for synchro transmissions due to extreme slipperiness. Meets GL-5 and GL-6 specifications. Replaces BMW SAF-XJ differential fluid for non-LSD.
  • 80W140 Gear Oil is similar to 75W90 but is suitable for heavily-loaded and low-speed differentials. It is not recommended for synchro transmissions due to extreme slipperiness. Meets GL-5+ and GL-6 ratings.
  • MTL Manual Transmission Lubricant is a 75W80 gear oil suitable for use in street and racing transmissions. Balanced friction speeds synchro engagement for faster shifting when warm; low temperature flow similar to an ATF improves cold shifting. Excellent protection for synchros, gears, and bushings. Meets GL-4 specifications. Use in place of 75W, 80W, or 75W80 gear oil; SAE 30, 10W30, or 5W30 motor oil; or ATF in manual gearboxes. Red Line MT-90 (Part No. 3344) is similar to MTL, but rated as a 75W90 gear lube; Red Line MT-85 (Part No. RL016) is rated as a 75W85 gear lube.
