Red Line 50104 75W85 GL-5 Full Synthetic Gear Oil for Hypoid Limited Slip Differentials - 4 Quarts

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.

Used for front and rear differential of my 2020 WK2/Grand Cherokee Trailhawk. No issues. Replace Red Lone fluid after 30k miles and it’s still pretty clean.

Changed differential fluid 15’ tundra , feels better and more responsive after fluid change

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

Meets toyota quality specs, but wish it came with a squeeze bottle. However I will take the quality oil and fill the diffs with a syringe than use the other major brand gear oils. Put in your 3rd gen tacoma and use with faith!

Good stuff

Great old for your deferencial.
