About AMSOIL oils
Amsoil has been making top-notch oils since 1972 and is today considered to be a leader in the industry and they keep striving at setting higher engineering benchmarks in their oils. The company has never lowered their formulas in a bid to cut costs but instead, manufacture oils with their own patented base stock oil technology to make it the best in the industry. Their products drastically outperform various conventional motor oils by effectively reducing friction and heat to give your vehicle or equipment maximum power for maximum performance and fuel efficiency.
While synthetic motor oils naturally have better molecular uniformity that protects and lubricates engines much better than conventional blends, even in cold temperatures. Amsoil oil, in fact, exceeds global performance standards and meets the warranty requirements of both domestic and imported motor vehicle engines. And as Amsoil has various blends formulated for specific applications, customers seeking the best performance oils with maximum protection, reliability and drain intervals prefer using Amsoil products.
AMSOIL’s molecular engineering is also a plus point as it’s not refined but synthesized oil. Refining doesn’t remove the oil’s impurities’ and has limited lubrication and performance qualities. On the contrary, Amsoil is impurity free and offers better performance and versatility. Besides, Amsoil oils are made using polyalphaolefins and the best additives. And as the company has much more years of experience than other companies their formulated oils offer the following advantages:
Heat reduction
They are helpful at reducing temperatures because of the oil’s natural resistance to high-temperature volatility. In other words, the oil doesn’t evaporate at moderate to high temperatures. This is the oil’s advantage over other blends that tend to vaporize to give heavier and thicker oils. Heavy and thick oils only leads to poor circulation, low fuel economy, and increased oil consumption.
All this however doesn’t happen to Amsoil products. On the contrary, these oils effectively protects all moving parts from potential damage and stress inflicted in high temperatures and high-stress conditions through minimal oil consumption, emissions and wear and tear. It actually cools down the lubricated systems so that they perform better for a longer time.
Increased shear strength
While most conventional oils have a shear strength of only 800 psi, Amsoil oil has much higher shear strength at 3,000 psi. This is how and why the oil maintains a sturdy and dependable lubricating film for engines in normal operating temperatures and conditions.
Longer drain intervals
Amsoil offers extended drain intervals as it has a much longer service life than petroleum lubricants and more. The extended intervals, in turn, reduce oil costs, wastage, environmental damage and of course, downtime. This especially proves to be a huge benefit to truckers because of reduced downtime, oil costs, and engine protection.
Amsoil products were in fact, the first oil to introduce this concept to the market in 1975 and have since then introduced quite a few long-drain synthetic diesel oils. Their recommended drain interval is after 25,000 miles or once a year.
Less oil consumption
Being highly stable oils, Amsoil synthetic lubricants don’t boil and evaporate even n extremely high temperatures. This leads to clean lubricated systems, longer engine life, and superior performance.
Reduced oxidation
It is the oil’s completely hydrogenated molecules and strong, uniform intermolecular bonds that protect it from oxidative damage. Oxidation however is inevitable, so the oil does undergo some oxidation to lubricate and keep your systems deposit free and corrosion resistant for a longer span of time. This helps prolong the oil life, which again leads to extended oil change intervals.

Better mileage
When compared to refined petroleum lubricants, Amsoil oils tend to develop reduced intra-lubricant drag. This benefits the lubricated systems because they use the fuel energy only to work, and don’t have to use it to overcome any form of drag.
Maintains fluidity at cold temperatures
Amsoil oil also boasts of a low cold weather pour point which means that the oil remains fluid even at temperatures as low as -75°F. This helps your engine start up easily in cold weather which in turn leads to faster lubrication, better protection, and the best fuel economy.
Better filtration properties
Unlike other engines, Amsoil oil and its air filters are much better than conventional filters in their ability to filter and trap and hold contaminants. It, in turn, helps to preserve the oil’s cleanliness for its improved performance and longer system life.
Large product line to choose from
Amsoil boasts of a large line of synthetic lubricants, motorcycles, advanced filtration systems, coolants and fuel additives that can be used in most commercial, industrial and consumer applications. In other words, you know and can rely on using Amsoil to protect practically any mechanical system or engine you use.
Company warranty
Amsoil is confident about their oils they even have a warranty for them. The company guarantees that their oils don’t cause any form of mechanical damage to your equipment, as long as the oils are used as per Amsoil recommendations. For example, according to oil analysis, their extended drain interval recommendation is a minimum of twice or more than the engine manufacturers’ recommendations. Even diesel Amsoil operators are protected during extended drains.
It’s all these features that make Amsoil much more chemically advanced oil that exceeds industry standards. It thus ranks high in the oil’s overall protection and performance as it also helps reduce oxidation and consequent sludge formation due to heat build-up, and a killer for today’s engines. To top it all, most motor oil test comparisons prove that Amsoil products are indeed superior quality synthetic motor oils, much more superior to petroleum motor oil.
