Red Line 57904 75W90 GL-5 Synthetic Gear Oil for Hypoid Limited Slip Differentials - 1 Quart (4 Pack)

Top of the line gear oil that will keep things running smoothly. Less noise from diffs than other brands I have used. Transfer case operates very quickly with no clunking going into 4WD.

Love everything about this stuff except changing it. This does what it is supposed to. The problem with that is trying to get spills cleaned up and getting it off your hands. I mean this stuff stays on whatever ittouches. Awesome for use in application, bad for the person who has to change it. I mean it is ideal for my Tacoma and 4runner. Amazing product. I have changed this out of the differential 3 times in nine years, never have I seen any, ANY metal pieces, slivers, filings/shavings on the plug magnets. Virtually no wear happening to the gears inside the differential. Try that with most other brands and see if you don’t see metal on the magnets.

After much of research online I settle with these stuff due to high ratings and recommendations. It matches what Suzuki GV takes for front, center and rear diff. Stuff are super thiccc and smelly, thicker then what came out of my diff... but I am not sure what was put there in first place by original owner. At the end I have not noticed any issues or changes in fuel economy after 1000 km with these stuff. Diff locks are switching fast... maybe faster then it was... but that might be placebo effect.

Changed my dif and manual trans oils on my 06 Tacoma. There was about 65,000 miles since last time with same oil. The oil looked perfectly clean and fine. I wasted money changing the oil. I guess that means the stuff works!

Best deal I could find for the best gear oil on the planet. Cheaper than getting it direct from Red Line Oil and I live less than three miles away from the factory.
