What Weight Differential Oil




Weight differential oil is a type of gear oil used in some rear-wheel drive vehicles. It is thicker than regular gear oil and helps to prevent the gears from slipping.

Differential oil is a type of motor oil that is used in vehicles with rear-wheel drive. This oil helps to lubricate the differential, which is responsible for transmitting power from the engine to the wheels. Differential oil typically has a higher viscosity than other types of motor oil, and it may also contain additives that help protect against wear and tear.

What Weight Oil Goes in the Differential?

Differential oil typically comes in two different weights, 75W90 and 80W90. The “W” in these designations stands for winter, meaning that the oil is designed to flow easily at lower temperatures. The first number indicates the oil’s viscosity, or how easily it flows, at low temperatures.

The second number represents the viscosity at high temperatures. So, what weight differential oil should you use? It depends on a few factors, including the climate you live in and the type of driving you do.

If you live in an area with very cold winters and do a lot of stop-and-go driving, 75W90 may be a good choice. For milder climates or if you mostly drive on highways, 80W90 may be a better option. Of course, it’s always best to consult your vehicle’s owner’s manual to see what weight of differential oil the manufacturer recommends.

What Weight Oil Goes in Rear Differential?

Differential oil weight is something that often confuses car owners. The truth is, there isn’t really one “weight” of oil that goes in the rear differential – it can vary depending on a few different factors. Here’s what you need to know about choosing the right weight of oil for your rear differential:

The first thing to consider is what kind of car you have. Different vehicles require different weights of oil in their rear diffs – so be sure to consult your owner’s manual or a trusted mechanic before making a decision. Another factor to consider is the climate you live in.

If you live in an area with extreme temperatures (hot or cold), it’s important to choose an oil weight that will perform well in those conditions. Again, your owner’s manual should have recommendations on this front. Finally, think about your driving habits.

If you do a lot of stop-and-go city driving or frequently tow heavy loads, you’ll want an oil weight that can handle those demands. Once again, your owner’s manual should have specific recommendations for these kinds of situations. Ultimately, choosing the right differential oil weight is all about knowing your vehicle and understanding your needs as a driver.

With a little research, you should be able to find the perfect option for your car – and ensure that its rear diff stays healthy for years to come!

Is Thicker Diff Oil Better?

The debate over which oil is better for differentials, thicker or thinner, has been going on for years. There are pros and cons to both types of oil. Ultimately, the decision of which oil to use comes down to personal preference and what works best for your vehicle.

Thicker differential oil has a higher viscosity, which means it is more resistant to flow. This can be beneficial because it helps to reduce leaks and keeps the differential cooler. Thicker oil also does a better job of protecting gears from wear and tear.

However, thicker oil can make it harder for the gears to turn, which can lead to increased fuel consumption. Thinner differential oil has a lower viscosity, which means it flows more easily. This can be beneficial because it helps improve fuel economy and makes it easier for the gears to turn.

However, thinner oil does not do as good of a job at protecting against leaks or reducing wear and tear on the gears.

How Do I Know Which Differential Oil to Use?

Differential oil is a lubricant that helps keep the gears in your car’s differential functioning properly. The type of oil you use in your differential will depend on the make and model of your car, as well as the climate conditions in which you drive. If you live in an area with cold winters, it’s important to use a differential oil that won’t thicken and become less effective when the temperature drops.

In hot weather, you’ll want to use an oil that won’t break down and start to form sludge. Your car’s owner’s manual will have recommendations for the best type of differential oil to use in your vehicle. You can also ask a mechanic or someone at an auto parts store for advice on which oil is best for your car.

Rc Diff Oil Weight Guide

There are a lot of different factors that can affect how your RC car handles, and one of those is the diff oil weight. This guide will help you understand what diff oil weight is and how it can affect your car’s performance. Diff oil weight is simply the measure of how thick or viscous the differential fluid is inside your RC car.

This thickness is important because it affects how much resistance there is to movement within the differential. A thicker diff oil will have more resistance to movement and be slower to respond, while a thinner diff oil will have less resistance and be quicker to respond. So, depending on your driving style and the conditions you’re driving in, you may want to adjust your diff oil weight accordingly.

Generally speaking, a lower diff oil weight will be better for high-grip surfaces like carpet or astroturf, while a higher diff oil weight will be better for low-grip surfaces like dirt or gravel. And as always, experiment until you find what works best for you!

Rc Differential Oil Explained

Differential oil is one of the most important fluids in your RC car. It helps to keep the gears and axles lubricated and running smoothly. Differential oil comes in a variety of weights and grades, so it’s important to choose the right one for your car.

The weight of differential oil is measured in ounces per square inch (OSI). The higher the OSI number, the thicker the oil. For example, 30-weight oil is thinner than 40-weight oil.

Grade refers to the quality of the oil. High-quality oils have lower pour points and higher viscosities than lower-quality oils. Differential oils also contain additives that help to protect against wear, rust, and corrosion.

These additives can improve performance in cold weather or under high loads. Some common differential oil additive packages include: – EP (extreme pressure) additives for increased gear protection

– anti-wear additives for increased bearing life – friction modifiers for improved traction

Rc Differential Fluid Substitute

Rc Differential Fluid Substitute Just like motor oil, differential fluid breaks down over time and needs to be replaced. When it’s time to change your differential fluid, you might be wondering if there’s a substitute that you can use.

Here’s what you need to know about using a different fluid in your differential. Differential fluid is designed specifically for use in differentials. It helps to lubricate the gears and bearings and keeps them cool.

Differential fluid also has special additives that help protect against wear and tear. So, while you might be able to find a substitute for differential fluid, it’s not likely to provide the same level of protection or performance as the real thing. If you do decide to use a substitute for differential fluid, make sure it’s compatible with the type of differential you have.

You’ll also want to pay close attention to how often you need to change the fluid. With inferior substitutes, you might find yourself changing it more often than with genuine differential fluid. In short, while there are some substitutes for differential fluid out there, they’re not likely to provide the same level of performance or protection as the real thing.

If you’re looking for the best possible performance from your differential, stick with genuine differential fluid.

Rc Differential Oil Weight

When it comes to RC differential oil weight, there are a few things to consider. The first is the terrain that you will be driving on. If you plan on driving on smooth surfaces, then a lighter weight oil is going to be best.

However, if you’re driving on rougher terrain, then a heavier weight oil is going to be necessary in order to protect your differential. The next thing to consider is the type of differential that you have. Some diffs require a thicker oil in order to function properly.

So, if you have one of these types of diffs, make sure to use the recommended oil weight from the manufacturer. Finally, your personal preference will play a role in what rc differential oil weight you choose. If you like the feel of a light oil, then go with that.

If you prefer a heavier feel, then choose accordingly. Just remember that the heavier the oil, the more protection it will provide for your diff – so keep that in mind when making your decision!


Differential oil is used to lubricate the gears in your car’s differential. The weight of the oil you use depends on the type of car you have and how it is driven. If you drive a car with a manual transmission, you will need a heavier oil than if you drive an automatic.
