Description

Red Line's Gear Lubricants are designed to provide the highest degree of protection and greatest efficiency for your drive train. Red Line provides a complete line of drive train lubricants which are optimized for differential, transmission, or transaxle use over a wide range of temperatures. Proper selection depends upon the manufacturers' requirements and whether the application is for passenger automotive, commercial, or racing use. Red Line Gear Oils contain polyol ester base stocks to provide excellent lubrication even under extreme conditions of high-loading and high- temperatures--their natural lubricity provide excellent slipperiness which reduces the sliding friction in hypoid gears to reduce wear and temperatures. The synthetic base stocks have a natural multi-grade property, so large amounts of unstable thickeners are not required to manufacture their gear oils, which means that Red Line Gear Oils will provide a stable viscosity for even extended periods of use. Red Line also manufactures gear oils which can be used in limited-slip differentials without the use of additional friction modifiers.

The Red Line 70W90 is the most popular gear oil, this is the preferred product in nearly all car and light truck differentials, both conventional and limited-slip. 75W90 is preferred for most racing applications. It contains friction modifier which is recommended for limited-slip units. 75W90 Gear Oil can be used in many transmissions and transaxles; however, other Red Line lubricants have better frictional properties for rapid synchronization. Exceeds API GL-5.

This oil is recommended for Subaru differentials.

Works good in 2002 wrx
Saltdscott56541 2 years ago
This fluid works great in my 2002 wrx. Don't listen to the people reviewing this who put this i there sti rear dif. The STI has clutches that Wes doesn't so the STI requires a different type of fluid

In my 03 WRX rear diff, I use Redline 75W90 at the recommended interval in my owners manual.The bad reviews come from Sti owners. NOT THE SAME DIFF!! , The WRX uses a viscous LSD where the STi uses a mechanical unit. I have 54,000mi on this oil in my rear diff and I haven't given it a second thought.

Not too sure.

I recently changed the fluid in the rear differential on my 2006 sti from the OEM fluid to this Redline 75w90 fluid. Initially there seemed to be no difference, but after 4 or 5 days I began to hear a metal on metal sound coming from the rear differential. After 7 days I couldn't stand the sound any longer, so I replaced the fluid with OEM fluid from the dealership. I don't know if the fluid hurt my LSD, but just to be safe I will keep the fluid OEM.

  • Q: is it ok for my diff  wrxridehawaii 6 years ago

    Answer

    Hi is this gear oil going to be ok in my Diff(04wrx)? or am i going to have problems like the guy with the 06 sti and his diff?


    • A: yeah this should work great, the WRX uses a viscous LSD where the STi uses a mechanical unit. While I have never seen any problems in an STi differential, I have used this personally in several of my WRX rear diffs and I love it. Thanks. :)
