What is the Subaru front differential fluid type? Primarily, Subaru utilizes two front differential fluid types: mineral oil or regular gear oil and synthetic differential fluid. So, it’s a lubricant designed to protect the front diff against friction and wear while extending lifespan.
But all synthetic liquid types aren’t ideal for Subaru’s front differential as the company allows only specific synthetic oil to reduce friction and keep the overall temperature low.
If you want to learn about which front differential fluid is permissible to use in your Subaru, you may continue reading this article.
Subaru Front Differential Fluid Type: Are There Many Variants?
Subaru’s automated front differential differs from its manual counterpart, as does the lubrication. An automated Subaru’s front diff uses distinctly different oil than the manual Subaru’s front differential.
So, speaking of the Subaru differential fluid type, while the manual transmission shares the transmission fluid with the front differential located at the gearbox, the automated one requires a different fluid type, which is basically the synthetic gear oil.
According to Subaru, all automated Subaru’s front differentials are rated to go with synthetic gear oil labeled with a “75W-90” rating with a “GL-5” marking.
That stated, if you are searching for the answer related to the 2010 Subaru Forester front differential fluid type or any other models, here you go:
If your vehicle features an automatic transmission, you should pick a 75W-90, GL-5 gear oil; otherwise, any regular gear oil will do the job.
