50104 75W85 GL-5 Full Synthetic Gear Oil for Hypoid Limited Slip Differentials - 1 Quart

Works great Toyota Tacoma 2018

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.

I purchased this to replace the rear differential fluid on my 2020 explorer and there’s definitely a noticeable difference in the performance. I will be using this again!

Shipped super fast. Arrived a day earlier than expected. Came in (2), 1 qt bottles. Great product - using this Friday on a GR Corolla for transfer case and rear differential fluid change. Only fluid I could get since Toyota has a National back order on their fluid and it’s about $100 for (1) qt.

Good replacement for the factory fluid.

worked fine met industry specs

Hasn’t destroyed the car so far so I guess it works well!

Highly recommend the Redline products! Save money , and every bit as good as the Toyota brand fluid!
