Hypoid Gear Oil Vs. Synthetic Oil: A Head to Head Comparison

In the modern world, we can see the use of different kinds of engine oils in automobiles. Among them, Hypoid gear oil and synthetic oil stand out the most.

Different people use different types of gear oil. It depends on their preferences and also on the kind of gear in their vehicles. But how do you choose between hypoid gear oil vs. synthetic oil?

Here, we are going to give all the information about both the oils and show you how both of them are beneficial in particular ways.

So, to end the hypoid gear oil vs. synthetic oil war and choose the perfect motor oil for your car, you must read this article.

Comparison of Hypoid Gear Oil vs. Synthetic Oil

Have a glance at the quick comparing table for a better understanding of these two oils.

Hypoid Gear Oil

To know about Hypoid gear oil, you must have some basic knowledge about Hypoid gear as the name came from there.

Well, in Hypoid Gears, the gearboxes are differently shaped where the axles never cross each other. The shaft of a Hypoid gear is smaller, and the surface of the gear part is a hyperbolic shape, rather not plane as the general gear design.

The specialty of this hyperbolic shaped gear is they never mesh with each other, and to keep them always cross-free, mesh-free, you need a lubricant with a minimum amount of EP(Extreme Pressure) additions.

So, the Hypoid gear oil is such engine oil that has extra chemical additives conducive to Hypoid gearboxes.

Performance

Hypoid gear oil is specifically for the hyperbolic shaped gearboxes. The oil makes such stable lubrication to keep hyperbolic shaped gear components wear-free.

So, the best-featuring performance a gear oil provides always keeps the parts of the differentials wearing free from each other. As a result, it helps to give a longer mileage and smooth transmission by the shaft.

Pressure Additives

The feature of gear oil that makes it different from other oil is that it contains some extra additional chemicals to work under acute pressure. And this feature makes it slightly different and compel it for a specific use.

The Hypoid gearboxes contain some differently designed metal parts. These parts help to transfer the torque with acute pressure and temperature. To maintain these parts work well with their respective weight and strength, the gear oil was invented.

Gear oil contains some extra additionals like Sulpher and phosphate to never breakdown under acute pressure.

Limited Slip

Hypoid gear oil, produced with such chemicals that has limited slip properties. So, the limited slipping feature makes the oil easily breakdown under any high pressure and temperature.

What We Like Most

• Perfect and ideal for the spiral beveled gear design
• EP additionals work best under intense pressure
• Lower viscosity performs well in any temperature
• Keeps the hyperbolic shaped gear parts wearing free
• Does not let the gear components intersect with each other

Well, Hypoid gear oil has little disadvantages also. and they are

What Could Be Better

• Waste of money if used for general bevel engines
• Extremely high price

Synthetic Oil

Now, let’s learn about synthetic oil. Synthetic oil is an engine oil made with chemical additives. It has two major types known as synthetic blend and fully synthetic.

Synthetic blend is a mixed oil of regular mineral oil and chemicals, whereas the full synthetic oil has no mineral itself instead entirely chemical-based. Or, you can check top rated synthetic oil for Hemi 1500 if it’s necessary.

Performance

Synthetic oil contains some chemicals that help to keep the engine components wear-restricted and friction-free.

Synthetic oil has enough viscosity to maintain perfect lubrication to the parts. It helps to run the parts smoothly and thus gives the desired mileage.

Flowing Properties

The synthetic oil can perform well under acute cold and also in average high temperature. It’s viscosity indexing properties are high enough to create flow in a temperature less than -40°.

Contamination-Free

Synthetic oil is produced in the laboratory by man, so it is contamination-free. So, this oil never gets black or remains dirt. The oil is a time saver as it does not need frequent replacement and also no need to flush.

What We Like Most

• Perfect for the engine going a high mileage
• Enough viscosity to create lubrication film around the engine parts
• Entirely impurities-free
• Keeps the engine parts wear-free
• Keeps the engine parts friction-free

Look what cons it does have.

What Could Be Better

• Not suitable for vehicles with Hypoid gear
• No chemicals for extreme pressure

Which Oil to Use?

Hypoid gear oil or synthetic oil, both have individual priorities. Both are well enough in their features, but the difference arises mainly in the application.

The Hypoid gear oil comes with appearances like75W-90, 80W-90, 85W-140, etc. whereas synthetic oil comes as 5W-30, 10W-40, OW-20, etc.

The Hypoid gear oil can run up to 50000 miles on average. On the other hand, synthetic oil can help to run the vehicle a maximum of 15000 miles on average.

So, which oil you should use depends on your engine model, design of the engine parts. You can use Hypoid gear oil on your general engine, but it will be like taking a money-wasting step. But if your can engine contains spiral-shaped gearboxes, then you must use Hypoid gear oil for the perfect mileage and betterment of the parts.

But remember whatever oil you use, it must be compatible with the given SAE-based grade. Never use any oil incompatible to the vehicle’s engine grade.

Final Verdict

The context includes complete details on Hypoid gear oil vs. Synthetic oil. If you are having any confusion between these two oils, then read this article, and it can clear out all your trouble. And then, you can select the perfect motor oil for your vehicle.
