Amsoil Vs Mobil 1 – Which Is the Better Engine Oil?
To the casual motorist, one engine oil is as good as another. As long as it does the job, right? But the point is which oil does the job best. Although Amsoil and Mobil 1 oils may share similarities, they also differ in certain aspects. And to make a decision, it is important to make a comparison of both.
Let’s take into consideration the following factors:
- Fuel Economy
- Engine Wear and Tear
- Heat and Cold Performance
1. Fuel Economy
One of the best ways to determine the efficiency of your engine oil is by checking your vehicle’s MPG (miles per gallon) when using a specific brand. MPG is the unit of fuel economy. The higher it is, the more efficient the lubricant is.
After several blind tests between the two motor oil brands, Amsoil yielded approximately 1.5 to 3.5 more MPG than Mobil 1. If you are looking for a cost- and fuel-efficient lubricant that will give you better mileage, then Amsoil is the best option for you.
2. Engine Wear and Tear
Next, we shall compare how effectively these lubricants protect the engine against wear and tear. Pitting the two engine oils against each other, researchers have found that Amsoil’s engine protection is superior to Mobil 1. Amsoil would be the better choice to protect your engine.
3. Heat and Cold Performance
When choosing the best engine oil for your vehicle, an essential factor to consider is how well they perform under high and low temperatures. I compared how each lubricant performed under conditions of extreme heat and cold.
It turned out that Amsoil fared better in colder temperatures. Mobil 1, on the other hand, thrived better in severely hot temperatures.
Do you reside in a place where the temperature usually drops to below zero levels? You will need a motor oil that won’t freeze on you if your answer is yes.
So, for colder climates, Amsoil is the better engine oil. But if you live in warmer climates, Mobil 1 is the ideal oil to use when you’re out driving under the hot summer sun:
| Amsoil | Mobil 1 | |
| Which is better in terms of: | ||
| – Engine protection from wear and tear | X | |
| – Heat-resisting capability | X | |
| – Cost- and fuel-efficiency | X | |
