Many debates are always running on which one is better between the Redline and AMSOIL gear oil. So if you are someone who wants to buy a gear oil but has not been able to buy any because of the confusion. Then you are in the right place. This article will discuss the Redline and AMSOIL gear oils and their features, pros and cons. So without wasting more time, let’s get started.

Redline Vs Amsoil Gear Oil

It is always tough to decide whether to use redline or amsoil gear oil. It becomes even more difficult when you are not well versed with the different lubricants. In this blog post you will learn everything you need to know about these two lubricants in order to make an informed decision.

Why Compare?

Both AMSOIL and Redline gear oil are different from each other. They have a different purpose, different work areas. Considering the price, they both have a similar range of pricing. But according to the customers, AMSOIL serves better because it gives ultimate protection to the engine, resists breakdown from high heat and controls thermal runaway.

But Redline is also giving a decent service to the engine. It offers an optimal service and maintains the cleanliness of the engine and other mechanical parts. Experts suggest that you go for AMSOIL if you have the budget; otherwise, you can always go with the Redline gear oil.

What Is Redline Gear Oil?

Redline oils are one of the best oil out in the market. The products go through controlled visual, computerized, and practical processes to give you the maximum performance. 

The redline gear oil is well known for its cooling additives, water wetter, etc. Also, it has so many applications for passenger cars, light trucks and racing vehicles. Additional friction modifiers are used in this oil for compatibility with clutch-type reduced slip differentials; however, most LSDs do not need different friction modifiers. 

Redline gear oil is not suitable for vehicles with manual transmissions because of its slipperiness which may cause further shifting problems in the machine.

Feature of Redline gear oil

Completely Synthetic Ester Formula Redline is well-known for its ester formula, ensuring long-term engine and mechanical component protection. This formula protects engine parts from soil and debris by stopping them from adhering to them. As a result, you’ll get the best results possible.

High detergency

Redline offers an immense quality of friction reduction and wears protection cause it has high detergency. It also maintains cleanliness via extended drain intervals.

Superior Oxidation Resistance 

Redline materials have high-temperature stability and oxidation resistance, allowing you to get more mileage out of your vehicle. This is because the lubrication of hot metal improves, while other synthetics thicken to the point that they cannot provide adequate mechanical component movement.

Natural viscosity

Redline gear oil has a natural viscosity index and less evaporation. That is why it can provide thicker oil film in areas like cams, bearings.

Pros of Redline gear oil

  1. Redline gear oil ensures long-lasting protection of the engine and other mechanical parts.
  2. It maintains cleanliness while offers wear protection and reduce friction.
  3. It allows an improved fuel economy.
  4. Redline gear oil provides thicker oil film due to the natural viscosity index.

What Is Amsoil Gear Oil?

AMSOIL severe gear lube is made explicitly for the severe-duty application so that it can give maximum performance. It is premium-grade gear oil. This cutting-edge AMSOIL production concept an exclusive mixture of high-viscosity, shear-stable synthetic base oils, as well as a unique combination of high-performance additives. The viscosity of the AMSOIL Severe Gear Synthetic EP Gear Lube is maintained for long-term protection against metal-to-metal contact.

The patented AMSOIL additives form an iron-sulfide barrier layer on gear surfaces, offering the ultimate line of protection against wear, pitting, and scoring. AMSOIL Severe Gear protects against “thermal runaway,” a condition caused by a lubricant’s failure to control friction and generate heat under high-stress conditions.

AMSOIL Severe Gear Synthetic EP Gear Lube prevents rapid lubricant corrosion and component loss by controlling thermal runaway. With AMSOIL Severe Gear Synthetic EP Gear Lube, the equipment can work faster and last longer.

Features of AMSOIL gear oil


AMSOIL performs far better than any other conventional oils. It offers better gear and bearing protection, extended service life, better heat and friction reduction.

Temperature extremes

AMSOIL Severe Gear EP Gear Lube performs admirably in both high and cold temperatures. It is resistant to high heat breakdown by nature, avoiding acids and carbon/varnish production. Its wax-free structure also increases cold-flow properties, resulting in better fuel economy and shifting in colder climates.


Towing, hauling, steep-hill driving, industrial use, racing, off-road use, fast acceleration, constant stop-and-go operation, and high atmospheric temperatures make AMSOIL Extreme Gear Synthetic EP Gear Lube ideal. Turbo-diesel pickup trucks, SUVs, buses, and delivery/utility vehicles are more vulnerable to extreme duty due to the higher horsepower, towing, and hauling capability of modern cars. Light, medium, and high-duty trucks, coaches, heavy machinery, 4X4s, tow trucks, rally cars, tractors, and motor homes are among the other severe-duty vehicles.

Pros of AMSOIL gear oil

  1. It gives 75% more protection to the engines, unlike other oils.
  2. AMSOIL ensures increased life to some critical engine components.
  3. Guarantee better cleaning from dirt and debris.
  4. You do not need to change this oil frequently because of its longevity.
  5. It gives 36% easier and faster cold starts.


If you read this article thoroughly, I hope that all your confusions already have been cleared. The debate will always be there, but you have to choose that gear oil, whichever meets your requirements.
