Maximized Engine
Performance

What's special about ZIC's solution is that it maintains the advantage of minimizing viscosity changes while maximizing the advantages of low-visosity engine oil, which helps engines start even at low temperatures and improves fuel efficiency.

ZIC's engine oil is formulated with VHVI Tech, a proprietary technology from SK enmove. This pioneering engineering technology reduces internal friction during engine operation and controls sensitivity to external temperature changes, maximizing both engine efficiency and stability.

VHVI TECH

VHVI(Very High Viscosity Index)Tech refers to technology that uses YUBASE that is known for ultra-high viscosity index. This helps with easy initiation at low temperatures, greater stability in the oil against oxidation, and better protection thanks to a strong oil film.

* Viscosity refers to the internal resistance of the lubricants against the flow of the lubricants caused by external force.
* The Viscosity index indicates the changes in viscosity in accordance with changes in temperature. A higher index is associated with less change and better functions as a lubricants.

Premium engine oils,
different from the base

Base oils make up 70% of engine oils and determine the overall function and quality. ZIC's engine oils are made of YUBASE, a leading premium base oil that has a market share of 40%*, setting the basis for overall premium quality. Here are some of the 10 keypoints that a powerful base oil can do to make the resulting engine oil stand out.

*Ranked first in terms of the share of the global market for GROUP Ⅲ premium base oils, as of year 2023

01Elevated engine protection

High Viscosity Index in any harsh circumstances such as extremetemperature and stressful conditions.

02Outstanding cleanliness

Through the application of the optimal additive mixing equation,sludges and sediments generated within the engine are minimized.

03Extended replacement interval

By maintaining the oil performance at its optimal state, it can be used for a longer period, leading to cost-savings.

04Improved fuel efficiency

Low viscosity minimizes oil consumption and by maximizes cylinder movement in the engine.

05Enhanced durability

By maintaining a powerful oil layer even at high temperatures, the wear and tear of the engine is reduced.

06Excellent Performance in low temperatures

Even at extremely low temperatures, ZIC oil circulates smoothly throughout the engine, ensuring excellent performance in cold conditions.

07Extended lifespan
of the engine

Outstanding engine protection and cleanliness can maintain ?like-new” engine conditions.

08Certified by global automakers

High quality factory fill-in oils and after-market products are offered to global automakers.

09Improved engine functions

Powerful engine output is maintained even in extreme operational environments.

10Reduced oil
consumption

Even at high temperatures, oil consumption is minimized, saving costs otherwise required for top-ups.

as well as hybrid vehicles

Fuel Efficiency Solution to minimize energy loss

Of the approximate 30,000 parts that form an automobile, 20% generate frictional resistance when the engine is in operation.

ZIC's engine oil, finely blended with YUBASE at an optimal ratio, minimizes frictional resistance and effectively solves causes of low fuel efficiency such as energy loss and engine overload.

Solutions with
a through design,
addressing the cause of undermined efficiency

ZIC's premium engine oil minimizes energy loss by addressing the shortcomings of each type of engine, from diesel vehicles that generate a lot of heat energy at high temperatures to hybrid vehicles that are prone to engine wear due to cold starts. Especially, the leading premium engine oils, ZIC X9000 5W-30 and ZIC X7000 10W-30, are optimized for diesel-powered cargo vehicles, protecting the engine from overload while improving fuel efficiency with their ultra-low viscosity.

	Problem	Solution
DIESEL	Low fluidity due to high viscosity features that maintain strong oil films when the engine undergoes compression ignition and generates high compression and heat energy.	ZIC's Fluid Solution effectively addresses the cause of energy loss for each type of issue, whether it be friction between parts, engine overload or loss of oil.
GASOLINE	Decreased engine protection performance due to sludge and sediment generated at high temperatures.
HYBRID	ncreased engine wear and tear under low temperature set for simultaneous operation of battery and engine.

Engine Protection
Solution

Even low-viscosity engine oil with low friction to increase fuel efficiency has its limitations. Because viscosity varies depending on temperature changes inside and outside the engine and on driving environment.

ZIC's solutions, which contain a high content of YUBASE known for its outstanding ability to maintain viscosity stability even during temperature fluctuations, not only keep the engine well lubricated and protected but also help extend the engine's lifespan and minimize sludge and sediments.

Test showing the change in viscosity index (VI) across different levels of YUBASE content

The viscosity index increases in proportion to the YUBASE content, showing that changes in viscosity caused by external temperature is less and the lubrication and circulation of the engine oil is effectively maintained.

Test results on relation to YUBASE and Viscosity modifiers

A higher YUBASE content is associated with a lower quantity of viscosity modifiers used and lower viscosity loss, indicating that viscosity is maintained at a stable level, which in turn helps protect the engine.

* Viscosity index improver (viscosity modifier): An additive that modifies the viscosity variations of lubricants at high and low temperatures, commonly used to improve the viscosity index.
** Those with a YUBASE content of 0 are used as Group II engine oil

for easier car maintenance : from excellent lubricating performance to outstanding cleanliness

Oxidation Prevention
Solution

Oxidation of the engine oil generates sediments and sludge in the engine and parts, prompting the need for frequent replacement of the oil. It also accelerates the ageing and damaging of the engine, pushing up maintenance costs.

ZIC's premium engine oil is a blend of highly refined Group III base oil and an additive blending formula designed to address typical engine problems, such as the formation of contaminants and other performance degradation factors. Through this approach, It can stave off common engine issues like sediment formation and oxidation.

Comparison of stability against oxidation and cleanliness at high temperatures

YUBASE, a lubricant of GROUP III grade, shows a similar level of stability against oxidation and cleanliness at high temperatures to those of PAO, which is GROUP IV.

Comparison of oxidation across different content levels of YUBASE

A higher YUBASE content is associated with better prevention against oxidation, leading to improved oil durability and improved cleanliness of the engine.
