Review: Great price and good quality - Works great Toyota Tacoma 2018
Review: Red Line compared to Original gear oil during Servicing - I changed the rear differential fluid in my 2021 Kia Seltos Turbo at 50 K miles. The original oil was clear. Checked and clean the magnet. Small amount of powered filings on magnet, normal condition. Replaced with Redline75W85 GL-5 Full Synthetic Gear Oil. The original fluid had a fish smell to it, possibly regular gear oil. The Redline nearly no smell and the oil felt more slippery on my hand. After fluid install, I drove the car in traffic and the interstate. I felt like I had a little more power and easier acceleration from a Stop. I can tell the rear end is quieter as well. Next I will replace the transmission fluid. Being a dual clutch the Redline MT fluid will hopefully complement the performance increase. It should increase MPG a little. Very Good lubricant.

## Questions & Answers

**Q: Does this work with my 2020 Toyota Landcruiser?**
A: Instead of these “check your manual” reply’s most Toyota difs use the 75w85 GL-5 for limited slip difs my 2020 4runner uses it. I’d say your good with using this fluid. By using other sources I found out but quantity wise I can’t exactly tell you since all difs take different amounts

**Q: Is this product compatible with a 2012 toyota 4 runner? red line page indicates this is the right one but amazon indicates is 75w90.**
A: Always consult with your vehicle owners manual mine states 75W85 for front and rear. 1.6qts for the front and 2.8 for the rear with rear locker. The transfer case requires special Toyota only 75W fluid.

**Q: Is this ok for 2016 rx350 transfer case and rear diff?**
A: It’s a synthetic oil but check your manual for proper weight required

**Q: Trying to figure this out - my ls460 calls for "lx" 75w-85 gl5 for transfer case and rear diff but "lt" 75w-85 for front diff.  what's the deal?**
A: Go ta an appropriate forum for help
