Good product
I purchased this for the front & rear diff in my 23 Tacoma. I got tired of the dealers high prices & Redline is one of the best product around. Shipping was quick & price was right.

Great product
Seems great! No issues, and a great alternative to the Toyota oil that sells for $130 a quart!

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.

original Toyota is 75w85, and it is that rating for fuel economy reasons
worked for Toyota Sienna, same oil for front and rear transfer case. While 75w90 and above oils will work for this transfer case, original Toyota is 75w-85 which is very hard to find aftermarket, and only red line came up. difference with a heavier oil is that you will loose some fuel economy, but it is good for towing and probably hot weather. Many people buy the original Toyota but it is way too pricey. Changed my transfer case oils, front and rear, and and used about half a gallon. Old oil was dark, probably wasn't changed by previous owner (vehicle came from Maine, no surprise). With the redline oil now in the transfer cases minivan feels a bit faster, or more sure off the line. Feels like the minivan shed about 100 pounds, as the old oil was like an anchor working more like sludge.
