I’m going to contrast Schaeffer VS Amsoil in this article. If you have any knowledge of the synthetic oil industry, you are likely very familiar with these two names.

They rank among the top, most well-known products available. In the realm of motor oils, an oil change is advised to be performed at about 5,000 miles.

When this practice is followed, you can count on your engine to run well for a very long time. If your car can reach the 250,000 mile milestone, you are operating at a greater level of vehicle longevity.

What if I told you that one of these brands has allowed for well over a million miles of driving with little to no engine wear? It’s true, and if you continue reading, you’ll learn which of these businesses provides this.

The Benefits of Synthetic Motor Oils

Synthetic oils have acquired acceptance over the past few decades, but recently there has been a greater uptake as more people are becoming aware of their advantages.

A stopped engine causes oil to collect in the oil pan. It only interacts once more at startup as a result. Normal oils usually need some time to lubricate the engine after leaving it. Because some elements are not yet lubricated, the biggest wear happens when an engine starts up.

Synthetic lubricants, on the other hand, enter the engine considerably more swiftly at first and do so in a more effective manner afterwards. Because of these factors, as opposed to the customary 5,000 miles, engines utilizing Amsoil and Schaeffer only need an oil change at a minimum of 20,000 miles.

Engine longevity has greatly increased, reaching 4 or 5 times the average. Additionally, if you install a bypass filter, your car’s oil change intervals will increase to 50,000 to 100,000 miles.

This is because the bypass filter does a great job of cleaning the oil of any impurities, extending its lifespan. And to top it all off, synthetic oils can improve your engine’s efficiency and reduce stress on it, which can result in a gain in gas mileage of up to 5%.

Overview of Amsoil

Amsoil As was already said, the company was established in 1969 with the intention of creating a superior product to what was already available.

Schaeffer Synthetic Oil

Today, you will notice that they have succeeded in reaching their objective. At this time, Amsoil is the brand that most people think of when discussing the advantages of synthetic lubricants. Amsoil works exceptionally effectively in almost every situation.

Both high-temperature conditions in which it is tested for flow result in it maintaining its viscosity. It was created to offer your engine the greatest level of protection. In comparison to Mobil 1 synthetic oil, it is thought to be four times better. Exclusively using Amsoil has been shown to increase vehicle longevity by up to four times compared to using normal engine oil. Bestop Vs Softopper Truck Cap : Which One is Right for You?

Overview of Schaeffer

The engines of vehicles that reached that mark were disassembled and inspected; aside from the requirement for new gaskets and seals, they were in excellent condition. By any measure, that is very outstanding. Since more than a century, business owners that operate industrial equipment have relied on this brand.

Schaeffer Oil vs Amsoil: Key Differences

Comparing them side by side is the most effective way to figure out which oil is best for you. This enables you to weigh the advantages and disadvantages of each oil in light of your particular requirements.

Schaeffer VS Amsoil Synthetic Oil

High-quality synthetic oils that shield your engine and increase its lifespan are Schaeffer and Amsoil. Prior to making your purchase, you should be aware of key variations between the two brands.

If you want an oil that can safeguard your engine and prolong its life, Schaeffers SynShield Full Synthetic Oil is a great option. The oil is developed to offer excellent protection against deterioration and stop deposits from building up on engine parts.

Compared to competing motor oils, the Next Generation AMSOIL Signature Series Synthetic Motor Oil is made to perform better. The oil is made to increase fuel efficiency while offering superior protection against wear and tear. AMSOIL’s premium synthetic technology is paired with leading additives from the industry to create a solution that goes above and beyond what modern engines require.

Oil Type

Unlike Amsoil’s oil, which is a premium synthetic, Schaeffer’s oil is entirely synthetic. The highest level of wear and tear protection and the avoidance of deposits on engine parts are the goals of full synthetic lubricants.

Superior to regular motor lubricants, premium synthetic oils are created to perform better. The oil is made to increase fuel efficiency while offering superior protection against wear and tear.


Oil’s viscosity is a measurement of its thickness. The viscosity of an oil determines how thick it is. There are four viscosities for Schaeffer’s oil: 5W-20, 15W-40, 10W-30, and 5W-40. Amsoil’s Signature, on the other hand, has viscosities of 5W-20, 5W-30, 10W-30, and 15W-40.

The table above demonstrates that the viscosity of Schaeffer’s oil is greater than that of Amsoil’s oil. As a result, the oil from Schaeffer is thicker than the oil from Amsoil.

Engine Type

Diesel engines should use Schaeffer’s oil, whereas gasoline engines should use Amsoil Synthetic Oil. An oil that is made to guard against wear and tear is necessary for diesel engines. Amsoil oil may not offer the same amount of protection because it is not designed for diesel engines.

Oil that enhances fuel efficiency is necessary for gasoline engines. Amsoil oil will increase fuel efficiency and is made for gasoline engines.


Amsoil lacks molybdenum but Schaeffer’s oil does. An additive called molybdenum aids in reducing friction and wear on engine parts.

While Schaeffer’s oil lacks zinc and phosphorus, Amsoil’s oil does. Additives like zinc and phosphorus aid in preventing wear and tear on engine parts.

Oil Change Frequency

Amsoil’s oil can be changed every 7000 miles, compared to Schaeffer’s 5000 miles. This means that the oil from Schaeffer will need to be changed more frequently than the oil from Amsoil.

You will need to change your oil every five months with Schaeffer oil and every seven months with Amsoil oil if you drive your car an average of 1000 kilometers per month.

Which is the preferable choice?

Despite the fact that both of these brands make excellent engine oils that provide amazing performance, Schaeffer comes out on top. By no means is this a slur against Amsoil. Simply said, we are comparing two excellent items, and only one can win.

By any means, Amsoil is not a subpar product; it simply suffers from being displaced by one that is marginally better. Despite being more than 60 years younger than Schaeffer, they have really done well to close the gap.


The information above suggests that Schaeffer’s oil is a better choice for consumers looking for an oil that will safeguard their engine and lengthen its lifespan. The oil is designed to guard against wear and prevent deposits from amassing on engine components.

Amsoil is a better choice if you want an oil that will improve fuel efficiency. The oil is designed to provide better protection against wear and tear while improving fuel efficiency.
