Both these engine oils are completely synthetic that are created for both diesel and gasoline engines, except for High Tech, which is only used with gasoline engines.
Energy has the Age-resistance technology which provides a decent oil film for reducing the friction between turning engine parts. It has a smaller total of lighter molecules which enhances its flashpoint temperature. This oil has viscosity modifiers to allow remarkable kinematic viscosities at all temperatures. It is best equipped to resist changes in viscosity due to temperature changes, hence, allowing higher viscosity index.
High Tech is highly compatible with multi-valve and turbocharged gasoline engines. It has excellent lubricating properties, providing the best wear protection by allowing low-temperature rapid oil delivery and high shear stability. This results in a smooth engine’s running, making this oil one of the best in terms of anti-wear and tear capability.
Premium is not compatible with the Diesel Particulate Filters (DPF) and Gasoline Particulate Filter (GPF) but is best suited with the catalytic converters. It keeps the engine clean with the highest concentrations of detergents. It is recommended in areas with cold weather due to its lower pour point temperature. It has an enormous number of base additives which increases its TBN and allows extended oil exchange periods.

Evaluation of Oil’s Burning Protection
The engine oil with a greater total of simpler molecules burn-off immediately and reaches its flash (Ignition) position at a lesser temperature. Consequently, a less volatile oil will have a higher flash point temperature.
Both High Tech and Premium have an equal flashpoint whereas Energy has a slightly higher flash point from both. This implies that it will provide the best oil’s burning security.

Difference of Engine Wear and Tear Defense
Anti-wear and tear extracts are present inside the oil to protect the engines’ turning parts by constructing an oil layer all over them. This layer reduces friction and ensures the smooth operation of engine. An oil with a greater sum of these additives will excel in lowering wear.
Energy has medium levels of zinc, phosphorus, molybdenum, and boron. This outcomes in an average motor oil in conditions of wear and tear lessening.
High tech with the highest concentrations of phosphorus, zinc and boron is the best oil to protect against wear, even with the absence of molybdenum in it.
Premium has the lowest quantities of zinc, phosphorus, and boron; however, its molybdenum concentration is the highest, but still, it is not enough to drastically improve its anti-wear performance.

Viscosity Comparison
Kinematic thickness is the tendency of a liquid to transmit motion through it. Elevated kinematic viscosity indicates the better flowing characteristics of an oil. If a motor oil has a less significant impact on its kinematic thickness by temperature changes, so its viscosity index will be elevated. Pourpoint is the freezing up warmth of a liquid.
Energy has the ultimate kinematic thickness at 40°C whereas High Tech has lower while the Premium has the smallest. The same trend is followed at 100°C, with Energy at the top, High Tech at the middle, and Premium at the bottom. Both High Tech and Premium have an equal viscosity index which is a little lower than that of Energy. With the lowest pour point temperature Premium stood first in winter-weather performance while High Tech in second and Energy on the third.

Converter Performing Analogy
After the oil burn-off, zinc and phosphorous ashes are left behind. This ash blocks catalytic converter, thus, hinders its implementation. The peak concentrations of phosphorus and zinc are found in High Tech, medium in Energy while the lowest in Premium. Therefore, Premium will deliver the lowest possible quantity of residue and is top suitable to be treated with converter.

Slurry Build-up Cut Difference
The corroded oil blends with the moisture along with dirt and additional debris to structure a thick liquid called slurry. This slurry hinders the smooth flow of oil inside engine, therefore, reducing its performance.
Energy has the lowest amount of calcium, making it least effective against sludge. Even though its magnesium amount is the highest, it does not improve its performance significantly.
High Tech with a medium level of Ca is the second-best oil in conditions of sludge reduction. Its magnesium quantity is the lowest of all, but it does not affect the oil’s performance that much.
Premium with the highest mass of calcium and the second-greatest quantity of magnesium is the most capable oil for battling versus the slurry.
Premium has the maximum amount of anti-foam agent silicon whereas High Tech and Energy both have an equivalent quantity of silicon which is comparatively lesser than Premium.
| Oils in Evaluation (5W-40 Grade oils) | Mg Concentration (ppm) | Ca Concentration (ppm) | Si Concentration (ppm) |
| Total Quartz 9000 Energy | 16 | 2478 | 3 |

Oil Change over Frequency Difference
The total base number is a representation of the total base additives available inside the motor oil which are necessary to defuse the acids created during combustion. Hence, a better TBN will lead to a longer oil drain interval, thus, a shorter oil change occurrence.
Premium with the highest TBN provides an oil change interval of 25,000 Km plus whereas the Energy with the second highest TBN is effective for 25,000 Km and in the end, High Tech with the lowest TBN has the shortest oil change interval of 20,000 Km.

| Total Quartz 9000 Energy | 9.1 |
| Liqui Moly Synthoil High Tech | 8.9 |
| Liqui Moly Synthoil Premium | 10.5 |
Price Differences
Premium is the bargain basement priced oil with a price label of 7.98 US dollars for a liter. Energy is a little costlier with a cost of 12.07 US dollars per liter while 14.2 US dollars per liter cost makes the High Tech costlier of all the oils in evaluation.
