Quaker State Advanced Durability vs Quaker State Defy High Mileage

Advanced Durability is conventional motor oil, meanwhile, Defy High Mileage is synthetic blend oil.

Advanced is generally more focused on increasing fuel economy while High Mileage’s focal point is shielding the engine from wearing.

Advanced provides superb catalytic converter performance due to its low ash production during the burning of oil. Large concentrations of detergents along with dispersants enable it to clean the deposits and sludge more effectively. The availability of a fewer number of lightweight molecules provides better protection against pre-mature burn-off. This oil experiences little changes in its kinematic viscosity due to its higher viscosity index.

High Mileage, due to its higher anti-wear additives concentrations, provides excellent engine degradation resistance. Detergents are present in decent numbers helping the oil to clean the sludge and other impurities. The higher kinematic viscosity of oil enables it to provide much-improved performances at both medium and high temperatures. It also excels in providing better cold startups. The affordable price of this oil on top of its commendable performance makes it one of the most budget-friendly oil.

Comparing Viscosity

Kinematic viscosity is defined as the difficulty in the smooth flow of fluid. The oil which possesses high kinematic viscosity will perform better during tough conditions such as high temperatures situations. Index of viscosity is an ability of an oil to oppose any change in its viscosity upon temperature variations. A greater index of viscosity ensures to serve this purpose more diligently. The pour point of any fluid is its minimum temperature beneath which it stops moving. The oil possessing a lower pour point will be better for extreme winter situations.

The working of High Mileage at 40o C is comparatively better because of its greater kinematic viscosity. When the temperature rises to 100o C both the oils perform almost identically due to their similar kinematic viscosities.

The index of viscosity of Advanced, however, is higher making sure to provide more consistent viscosity during the temperature switch from medium to high. The cold condition performance of High Mileage is slightly better than its peer due to its lower temperature of pour point.

Contrasting Oil Replacing Interval

The acid formation as a result of oil ignition causes corrosion in the engine. Bases are added as additives to neutralize these acids. These base concentrations are generally estimated in TBN. A higher TBN makes sure a lower frequency of changing the oil thus increasing fuel economy.

Advanced has a higher TBN allowing longer durations of interchanging the oil. This oil is recommended to be exchanged after every 5,000 miles providing higher mileage compared to its peer.

On the other hand, the interval of replacing oil is shorter for High Mileage. This is because of its lower TBN than its rival. The oil is required to be interchanged after covering a distance of almost 3,000 miles.

Contrasting functioning of Catalytic Converter

Ash is produced upon the interaction between oxidized oil with anti-wearing agents like zinc along with phosphorus. The clogging occurs when this ash sets into a catalytic converter. This blockage act as a hurdle in its proper functioning, decreasing its efficiency.

Advanced possess these wearing-resistant compounds in fewer amounts. Their lower concentration causes oil to produce less ash, resulting in a more effective functioning of the catalytic converter.

The concentrations of primary anti-wearing compounds are higher in High Mileage. It results in lower efficiency of the converter due to its higher clogging problem. This puts it a step behind its counterpart in terms of catalytic converter performance.

Contrasting Oil Sludge build-ups

Calcium is present as the main detergent constituent in Advanced oil to lower the sludge build-ups. The concentration of magnesium in the oil is comparatively very low. Anti-foaming agent (silicon) is also present in a slightly lower amount. But due to generally higher concentrations of sludge reducing agents, it is marginally superior to its peer.

High Mileage contains calcium in abundant numbers to assist in lowering sludge formations. The magnesium is present in higher quantities compared to rival oil. However, the overall concentrations of the detergents present in the oil are lower making it second to its counterpart in this regard.

Comparing Oil Early Ignition

The presence of lighter molecules in a lower amount makes Advanced less volatile. So as a result, it has a lower flash point temperature, providing better protection against quick oil burning.

High Mileage contains these lighter particles in relatively higher numbers. The rate of evaporation is therefore high which increases its volatility. The higher evaporating rate causes its ignition point to be lower, giving lesser protection from pre-burning of oil

Comparison of Engine Wear-off Protection

The contact of the engine parts with each other produces friction. The friction further leads to engine wearing, decreasing its life. Anti-wearing supplements are added to the oil to minimize this issue. The function of these additives is to construct thin layers about these moving engine components. The layer minimizes their interaction, providing high lubrication and low engine wearing. The availability of these supplements in higher amounts ensures better resistance against wear and tear.

Overall, the concentrations of anti-wear compounds present in Advanced are comparatively on the lower side. Molybdenum is present in larger quantities. However, it is still behind its competitor because of its lower quantities of these supplements on the whole.

Meanwhile, High Mileage performs well in terms of protecting the engine from these damages because of its larger concentrations of these wear-resisting compounds in general. The concentrations of both zinc and phosphorus in the oil are very high. Secondary anti-wearing agents like boron and molybdenum are also present in higher numbers, to ensure better performance of the oil by providing high resistance against the problems of wear and tear.

Difference in Price

Advanced is more expensive than its peer. This is because of its higher oil exchanging intervals, resulting in a better fuel economy that justifies its higher price. The cost of 1 Quart bottle is nearly 7.52 US Dollars. Meanwhile, High Mileage is more budget-friendly oil because of its relatively lower price. The per Quart bottle comes in with a price tag of around 4.28 US Dollars, giving excellent resistance against engine wear at a much less price.
