Default Diff Fluid Question

Still new to Nitro....What is the pupose of thicker or thinner diff oils. I know how a diff works with touring but seems different with Nitro Bubby. Can you give me some input?

think of this like a 2wd jeep at the beech. if you drive on the sand , you have to be careful, of you will dig out under a wheel ( that wheel is stuck in the sand, when it spins, it does nothing in moving the car) . even though the other wheel is touching the ground, it has no power because of tthe differential, putting all of that power to the usless, spinning wheel.

now, lets say you put in a thick, stiff oil. the differentials action is slowed/limited. so both of the rear wheels will then have power, and be able to get allong through the sand.

that is similar to 2wd buggies. rougher conditions may require thicker oil. while smoother conditions use thinner oil.

good luck

They are different depending on where you are in the car.
Front uses oils to tranfer power side to side when turning, slowing down and speeding up. Thick stiffens it up and thin lets the wheels run more independant.

Center diff controls how the car acts front to back. Thicker is more of a locked 4 wheel feeling. Thinner oil lets the power transfer from the back to the front when you speed up. It also transfers power from the front to the back when you load the front end when you are slowing down.

The rear diff allows the car to steer into a turn when the oil is light but it will be soft coming out of a turn when you speed up. When the oil is thick you will have to rotate the car into the turn. When you come out of the turn and hit the gas it will straighten up and push more.

You will have to play with what you like for your driving style and how much traction you have.
Good luck,
