Engines work hard in the heat of the UAE. From Dubai to Abu Dhabi, cars face long drives, heavy traffic, and extreme weather. In these conditions, oil must perform at its best. One of the key parts of engine oil that makes this possible is the viscosity index improver that UAE manufacturers rely on. But what is a viscosity index improver? And why is it so important for vehicles in the UAE? We will also discuss the impact of Chempol in the additive industry thanks to their high-quality formulations. Let us explore.
To know what a viscosity index improver does, you must first understand viscosity. Viscosity is a measure of the thickness or thinness of oil. Thin oils flow easily, while thick oils flow slowly. Engines need oil to protect moving parts. If oil is too thin at high heat, it will not protect well. If it is too thick at a cold start, it may not flow fast enough. This is why oils are rated with grades, such as SAE 10W-40 or SAE 5W-30. These numbers show how the oil behaves in cold and hot temperatures. A viscosity index improver makes sure that the oil can adjust and work across both.
A viscosity index improver is a type of oil additive. It helps oil keep the right thickness across a wide range of temperatures. It is also called a viscosity modifier additive UAE manufacturer often use in engine oils. At low temperatures, the additive allows the oil to stay thin enough to flow. At high temperatures, it stops the oil from thinning too much. This balance ensures that engines get the same level of protection in all conditions.
VI improvers are usually made of polymers. These are long-chain molecules that react to heat. At a cold start, they stay coiled and small, letting oil move easily. When the heat increases, the polymers stretch and expand. This helps the oil stay thick enough to protect engine parts. This process is why they are often called VI polymers. They are key to making multi-grade oils that can handle both cold starts and desert heat.
The UAE has one of the harshest climates for vehicles. Summer temperatures can reach extreme highs. Engines run hot in long traffic jams. Oil without the right VI improver would thin out too much and fail to protect.
This is why UAE manufacturers value viscosity index improvers. They help oils remain stable in both city and desert driving. Whether it is a sports car, SUV, or truck, oil with VI improvers ensures smooth engine function.
Manufacturers also know that drivers in the UAE demand reliability. Expensive cars, high-speed highways, and tough weather require oil that will not break down. With the right VI improver, oils last longer and give better protection.

Many benefits come from using oils with quality viscosity modifier additives that UAE manufacturer recommend:
These benefits show why manufacturer across the UAE always check if oils have strong VI polymers.
Not all VI improvers are the same. Different oils use different polymers to achieve stability.
A trusted VI improver supplier UAE provides these polymers in oils suited for both light and heavy vehicles.

In the UAE, most cars use multi-grade oils like 5W-30 or 10W-40. These oils are only possible because of VI improvers. For example, a 10W-40 oil acts like a 10-weight oil at low temperatures and like a 40-weight oil at high temperatures. The VI improver makes this dual behaviour possible. Without the VI polymer, oil would be single-grade and unsuitable for the wide range of temperatures found in UAE driving.
While VI improvers are vital, they are not perfect. Over time, polymers can break down due to stress and high heat. This is called shear. When this happens, oil may lose its ability to protect. Manufacturers in the UAE know that frequent oil changes are still needed, especially in extreme driving conditions. Using oils from a trusted VI improver supplier ensures that the polymers are of high quality and last longer. This is why many drivers in the UAE choose premium brands that use advanced viscosity modifier additives.
Manufacturers in the UAE often see the results of poor oil choice. Engines overheat, parts wear fast, and cars face breakdowns. When oil lacks strong VI improvers, these problems happen more often. That is why manufacturers in the UAE always recommend oils with high-quality VI polymer products. They know that these polymers protect engines from the country’s unique driving conditions.
The demand for advanced VI improvers is rising in the UAE. With more luxury cars, sports cars, and commercial fleets on the roads, oils must perform at higher levels. New viscosity modifier additives technologies are being developed. These next-gen polymers will resist breakdown, last longer, and improve fuel efficiency. As the UAE moves toward higher performance and eco-friendly standards, VI improvers will remain vital in oil blends.
