These completely synthetic motor oils can be utilized in both types of engines diesel as well as gasoline. High Tech specializes in cleaning engines from deposits, Top Tec 4100’s center of attention is protecting the engine against degradation.
Liqui Moly High Tech has lower zinc and phosphorus quantities excel in providing superb catalytic convert performance. The larger detergent concentrations ensure excellent cleaning of the engine from sludge formations. This oil provides commendable performance during extreme temperature conditions. A higher TBN allows a longer time span for changing the oil. The affordable price also makes it one of the most economical motor oils as it provides better value for the invested money.
Liqui Moly Top Tec, on the other hand, provides exceptional wear resistance because of its high anti-wear additives. A decent amount of detergent added to the oil enables it in minimizing the production of sludge. The oil ensures protection against its premature ignition as it exhibits a fewer number of lightweight molecules. The performance of the oil is quite admirable during elevated temperature situations. High viscosity index makes sure that it retains its kinematic viscosity during fluctuations in temperature.

Comparing Oil Viscosity
Kinematic viscosity is the estimation of oil hindrance to flow. A high kinematic viscosity ensures oil dominant functioning during exaggerated temperature circumstances. The capability of oil to oppose any viscosity variation is known as Viscosity Index.
The high viscosity index enables the oil to conserve its viscosity at high temperatures. A pour point is a minimum temperature under which oil losses its flowing ability. The oil exhibiting a lower pour point allows it to provide better performance during colder environments.
The performance of High Tec is above its counterpart in the course of normal and high-temperature conditions. This is because of its marginally higher viscosity at both 40 o C and at 100 o C as well. But Top Tec is ahead of its competitor in retaining its viscosity when the temperature rises from standard to high due to its high viscosity index.
The lower pour point temperature of High Tech allows better startups during cold temperature situations.
| Oils in Contrast (oils grade 5W-40) | Kinematic Viscosity during Normal temperature (40o C) (mm2/s) | Kinematic Viscosity during Elevated temperature (100 o C) (mm2/s) | Index of Viscosity | Pour-point |
| High Tech | 90.2 | 14.5 | 167 | -45 o C |
| Top Tec 4100 | 88 | 14.3 | 169 | -42 o C |
Comparing Oil Exchanging Frequency
Bases included in motor oil determine its changing intervals. TBN is normally used to measure these bases’ concentrations. The purpose of their addition is to counteract the acids that are devised during the oil ignition process. This procedure leads to a decrease in their concentrations over time.
The presence of these additives in larger numbers ensures lower oil exchanging frequency.
TBN of High Tec is higher than its peer providing longer durations of changing the oil. This oil is demanded to be replaced after an average interval of 40,000 Km.
Top Tec, in comparison, gives short intervals of interchanging as it has a comparatively lower TBN. The minimum distance for exchanging oil is about 30,000 Km.
| Oils in Contrast (Grade of oils 5W-40) | TBN (mg KOH/g) |
| High Tech | 9.3 |
| Top Tec 4100 | 7.5 |
Contrasting Catalytic Converter working
The ash residue formed as a result of the reaction between ZDDP compounds (zinc and phosphorus) and oxidized oil is extremely harmful to the catalytic converter. This residue moves into the converter which causes its blocks. The blockage makes the converter unable to perform properly, reducing its efficiency.
The concentrations of ZDDP compounds are considerably low in High Tech, resulting in relatively lesser ash production. Less ash build-up enables the converter to perform better than its counterpart.
Phosphorus and Zinc compounds are present in comparatively higher concentrations in Top Tec. It leads to a greater ash formation, causing more hindrance in the proper catalytic converter functioning.
Comparing Sludge Formation of oils
Interaction of the impurities such as dust and moisture with the ignited oil leads to sludge generation, which is a thick black viscous fluid.
The sludge inhibits the proper oil movements, causing hindrance in regular engine working. To minimize the problem of sludge production, oil is generally equipped with additives like detergents in addition to some dispersants. The function of these additives is to reduce these sludge issues.
The cleaning ability of High Tech is marginally ahead of its counterpart, due to greater concentrations of detergent additives. The higher detergent quantities enable the oil to produce a lower amount of sludge leading to better engine working.
Conversely, detergents are present in slightly lower amount in Top Tec which forces the oil to provide relatively lower cleaning of deposits. This makes the oil second to that of its peer in terms of engine cleaning.
Oil Quick Burning Protection Comparison
The concentration of lighter particles present in the oil determines its volatility. If these particles are present in greater quantities, it increases oil’s volatility. This is because these light molecules will effortlessly break down at high temperatures, enabling the oil to evaporate rapidly. It enables oil to outreach its ignition point at a lower temperature, providing less protection against the early oil burn-off.
High Tech, in comparison, possesses a faintly lower flashpoint temperature. This is due to the presence of relatively higher concentrations of these delicate molecules, making it slightly more volatile compared to its rival.
On the contrary, Top Tec contains fewer numbers of these lighter molecules. This enables the oil to reach its flashpoint at comparatively higher temperatures, providing better protection from the early burning of oil.
| Oils in Contrast (Grade of oil 5W-40) | Flashpoint Temperature (o C) |
| High Tech | 230 |
| Top Tec 4100 | 232 |
Comparing protection against engine wearing
The continuous sliding of engine metal parts over each other produces friction. The higher this friction, the greater will be engine wearing. Wearing-resistant supplements help in lowering this cause. The purpose of these additives is to develop a thin lubricating film around these metal components. The film restricts them to make contact with each other, providing better lubrication.
Anti-wearing additives, usually zinc and phosphorus compounds, are available in comparatively lesser amounts in High Tech. This lesser concentration leads to lower shielding from the degradation of the engine, causing it to be behind its competitor in this regard.
Top Tec contains wearing-resistant additives in greater quantities leading to stronger layer formations around moving parts of the engine. This results in high lubrication and relatively lower engine wear.
