What kind of fluid does a gr86 diff take?
The GR86 (also known as the Toyota 86 or Subaru BRZ) uses a limited-slip differential that requires a specific type of differential fluid. The recommended fluid for the GR86 differential is a high-performance, synthetic gear oil.
Differential Fluid for the GR86
According to the GR86 owner's manual, the recommended differential fluid for the vehicle is a 75W-85 or 75W-90 synthetic gear oil. This type of gear oil is designed to provide the necessary lubrication and friction characteristics for the limited-slip differential in the GR86.
The GR86 differential is a Torsen-type limited-slip unit, which means it uses a set of gears and clutches to distribute power between the left and right wheels. This type of differential requires a specialized gear oil that can handle the increased friction and load compared to a standard open differential.
Reasons for the Specific Fluid Recommendation
There are a few key reasons why the GR86 manufacturer recommends a 75W-85 or 75W-90 synthetic gear oil for the differential:
- Viscosity: The 75W-85 or 75W-90 viscosity is optimized for the operating temperatures and loads experienced by the GR86 differential.
- Friction Characteristics: The synthetic formulation and additive package in the recommended gear oil provides the necessary friction characteristics for the limited-slip differential to function properly.
- Durability: Synthetic gear oils are more resistant to thermal breakdown and provide better protection against wear compared to conventional mineral-based oils.
Using the wrong type of differential fluid in the GR86 could lead to increased wear, reduced performance, and potentially even damage to the limited-slip differential over time.
Which diff oil do I need?
The 3000 cSt oil is thin enough to allow easy cornering and thick enough for accelerating because it makes the other rear wheel retain traction. If you want your car to accelerate a little faster when exiting corners and better cornering with throttle, we'd recommend 7000 cSt oil in the center diff.
How much fluid does a Toyota 86 differential hold?
1.1 – 1.3 Liters
Differential: 1.1 – 1.3 Liters of 75W90NS. After draining, fill until the fluid is dribbling out of the fill hole. Be sure to use fresh washers for both the drain and fill bolts. Transmission: 2.2 – 2.4 Liters total capacity.
How much oil does a BRZ rear diff take?
GR86 / BRZ takes 1.22 qt. (1.15 lt.)
What type of lubricant do you use for a rear differential?
Regardless which type of differential you have of those listed here, use a high-quality synthetic gear lube. Many manufacturers now install synthetic gear lube at the factory and recommend it as the service fill.
Is diff oil the same as ATF?
Differential and transmission fluid are two different automotive fluids primarily because they serve two difference functions. One fluid is for vehicles with manual gearboxes and the other for automatic transmission vehicles.
What fluid should never be used in a rear differential?
Never, under any circumstances, put engine oil in your differential. This will result in devastating damages to your engine. Engine oil is much different than gear oil, mostly it cannot withstand high pressure.
What kind of oil does a Toyota rear differential take?
75W85 gear oil
Currently, in the United States, Toyota recommends a 75W85 gear oil that also meets GL5 standards to be used in the rear differential of 2009-2023 Toyota Tacoma models. A popular gear oil part number is Toyota 08885-02506, though there are others that may be referenced.
When should I replace my Toyota differential fluid?
For top performance and reliability, we recommend exchanging the differential fluid every 30,000 miles.
What oil does gr86 use?
Oil Grade: API*
| Viscosity: | 0W-20 (All TEMPS) |
|---|---|
| Capacity: | 5.3 quarts (with filter). After refill check oil level. |
| Torque: | 31 ft/lbs (Oil Drain Plug) Install a new washer on the drain bolt. Only use an OE drain plug. |
What type of fluid goes in the rear differential?
Think engine oil but thicker; it's similar to fluid that's used to lubricate manual transmission gears. There are two basic types of differential fluid: Mineral oil, which is a natural, crude oil-based fluid. Synthetic differential fluid, which is created with chemicals and can be fine-tuned for optimal performance.
