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.
- 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.
