A Detail Comparison Between Amsoil vs Mobil 1

Have you a clear picture of the oils overview, right? But, we know you aren’t satisfied with the information, yet look for a side-by-side comparison. 

So why late? 

Here’s what you are waiting for. 

1. Authority Standards

Human psychology always prefers to believe in any product certified by any authority institution. It’s not different in the case of engine oil. 

Even the oil which meets, is certified or exceeds the country’s highest authority institutions’ standard has less chance of being outdated, poor in quality, and inefficient. 

In the engine oil sector,

  • API (American Petroleum Institution), 
  • SAE (Society of Automotive Engineers), and 
  • ACEA (European Automobile Manufacturers’ Association) works as the authority. 

So let’s first check out their quality in meeting those standards. 

  • Amsoil

Amsoil got approval from ACEA A3/B3, E2, E3, E5, and E7, API CI-4+/ CI-4, CH-4, CF, CF-2, SL, SJ. You may not be familiar with these words. But, still, it boosts your confidence that it’s a quality oil. 

  • Mobil 1

Mobil 1 meets ACEA (A1/B1, A5/B5, API SN, SM) and ILSAC GF-6 standards. It’ll help the oil offer low-speed pre-ignition (LSPI) wear protection to keep it clean. 

Winner: Tie 

2. Oil Type

You’ll find different types of motor oils in the market designed for different powered engines. Such as conventional, semi-synthetic, synthetic, fully synthetic, and advanced fully synthetic. 

On the other hand, some engines are powered by gas, some are diesel, and some are petrol. It’s important to check out your engine to choose its oil. 

  • Amsoil

Amsoil comes with premium synthetic oils that are compatible with gasoline engines. Once you put this oil in the stomach of your gas-powered Ford Mustang GT, Chevrolet Camaro SS, or Dodge Challenger R/T, they’ll perform at their peak. 

  • Mobil 1

Here you get the advantage of using the Mobil 1 motor oil, as you can use it on your Gasoline plus Diesel engines because it comes with 2 formulas, advanced synthetic and fully synthetic. 

No matter if you have a Porsche 911 GT3, BMW M5, or Mercedes-Benz AMG GT R that needs advanced synthetic oil. Or Lexus LC 500h, Audi S4, or Nissan GT-R Nismo that needs full synthetic oil, Mobil 1 will be your best fit. 

Winner: Mobil 1 

3. Formulation

You may find the engine oils just a liquid. But, in terms of technical parts, many chemicals are blended to form the oil. That means the right amount of chemicals in the oil, the better it will be.   

  • Amsoil

This oil contains detergents, dispersants, anti-wear agents, rust inhibitors, and friction modifiers. Having all those additives, it offers better thermal and oxidative stability. 

Less thermal breakdown improves wear protection, mileage efficiency, and low-temperature performance. 

  • Mobil 1 

If you check the Mobil 1 oil formula, you’ll get approximately 1,000 ppm of ZDDP, phosphorus, and many other chemicals. Generally, all those additives ensure faster oil flow in the engine’s internal components to protect against wear and tear. 

Moreover, these detergents also prevent sludge and deposits from building up in the oil to keep it clean. 

Winner: Tie 

4. Viscosity Level H3 

In the engine oil industry, viscosity grade indicates the ability to protect heat. The lower-numbered engine oils are thinner and great to use in colder climates. 

On the other hand, the higher-numbered oils are highly heat resistant and good to use in the summer. 

  • Amsoil

Amsoil comes with 5W-20, 5W-30,10W-30, and 15W-40 viscose oils. So, it’ll perform better in low temperatures and winter-based areas. If you live in Fairbanks, Barrow, or Minnesota, Amsoil will be a good fit for your vehicles. 

  • Mobil 1

However, Mobil 1 offers hot and low-temperature-resistant engine oils as you find its oil viscosity from 0W-16 to 15W-50. So whether you are in sweat-breaking hot weather or freezing cold weather, Mobil 1 will be your cup of tea. 

Winner: Mobil 1

5. Oil Changing Interval

Is it possible to drive your vehicle with the same oil in its lifetime? 

Absurd, right? 

On the flip side, do you love to change the oil every few miles of running? 

No, you don’t.

Here comes the oil that offers you longer changing intervals and keeps the engine healthy and at optimal efficiency. 

  • Amsoil

Amsoil offers a higher oil changing interval of up to 25,000 miles or 40,200 km. Or, it keeps your engine optimized for 700 hours of running in a year. 

You can even longer the operation time and oil changing interval by installing single or dual oil by-pass kits in the engine. 

Mobil 1

This oil protects your engine with peak performance up to 10000 miles or one year of use between oil changes. Though it won’t need frequent oil changes. But, still, you need to change oil 2.5 times more than Amsoil oil
