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.
- 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.
