Amsoil Motor Oil or Mobil 1 Motor Oil?

While there might be many similarities between the oils that are offered by the two manufacturers, the thing that you should consider before making a decision is the differences that lie in between them.

To help you in making an efficient decision, we would like to present to you the key differences between them. They are:


The MPG is the unit of the fuel economy that is used to determine how efficient the fuels are.

And the more the MPG, the better the oil. In this, when the two of the lubricants were tested, Amsoil always gave around 1.5 to 3.5 more MPG than Mobil 1.

That concludes that Amsoil is more efficient than Mobil 1. So, if you were looking for a cost-efficient oil, you should opt for Amsoil.

Engine Wear

When the two of the oils are put head to head against each other for finding out which one protects the engines most in the case of wear, it can be seen that Amsoil offers better protection than Mobil 1.

Keeping that mind, we can say that Amsoil will protect the engine better than Mobil 1.

Heat-Resisting Capability

Getting adequate performance in extreme temperatures is one of the key factors that you should consider the most when choosing the next oil for your car.

In this case, when the two of the oils are put against each other, we found out that Amsoil could handle colder temperatures better than Mobil 1.

On the other hand, for extreme heat, Mobil 1 went a bit ahead than Amsoil.
So, we would suggest you to opt for Amsoil for colder environments and for the summer heat, you can go for the Mobil 1.


We hope we were able to help in the case of choosing the next oil for your engine for getting optimal performance and extended lifespan.

With that, we would like to conclude our take on Amsoil vs. Mobil 1 by wishing you good luck and hoping that you get the most out of your engine.
