1. [Engine Oil Additives] Why should I use this product?

   The primary reason for using an engine oil additive is to protect the engine. For an engine to operate properly, the performance and lifespan of the engine oil are critical. When oil performance deteriorates, wear and damage begin to accumulate inside the engine. The problem is that many drivers neglect proper engine-oil maintenance, allowing these issues to worsen over time.
    

   For this reason, we recommend engine oil additives to drivers who may not always keep up with ideal maintenance intervals. PowerDrag Engine Oil Additives are designed to maximize the performance and durability of your engine oil until the next oil change, helping protect the engine and reduce long-term wear.

2. [Engine Oil Additives] There are two types of products. How should I choose between them, and which engine oils are they compatible with?

   The “Original” Engine Oil Additive is suitable for all vehicles and all engine types, and it can be mixed with any engine oil. It is compatible with viscosity grades ranging from 5W20 to 5W40. Because the additive’s viscosity is formulated close to 5W30, adding it to a 5W20 oil may cause a slight increase in overall viscosity. The “Original” additive is recommended for drivers who mainly do city driving or steady-speed commuting.
    

   The “Feedback” Engine Oil Additive is designed with superior thermal stability, making it ideal for high-performance engines with six cylinders or more, turbocharged vehicles, and drivers who enjoy sporty driving. It contains ESTER base oil, offering excellent thermal conductivity and maintaining stable oil pressure during high-speed driving—making it especially suitable for supercars and turbocharged engines that generate high temperatures. Because its viscosity is formulated close to 5W40, it is best used with oils in the 5W30 to 5W50 viscosity range.

3. [Engine Oil Additives] What benefits can I expect?

   PowerDrag Engine Oil Additives enhance the lubricity and oxidative stability of engine oil, while delivering excellent performance in forming a strong oil film and tribo-film. This reduces metal-to-metal friction heat and promotes smoother piston movement. As a result, drivers can expect significant reductions in vibration and noise, along with improvements in power output and fuel efficiency. The additive can also help extend the oil change interval by up to 20%.

   In particular, the Feedback High-Performance Engine Oil Additive is formulated using some of the finest base materials available in Korea. Its outstanding thermal stability at high speeds provides superior acceleration performance and a high level of driver satisfaction.

4. [Engine Oil Additives] Are there any precautions when using the product?

   Since the product comes in a 200 ml bottle, you can add it without performing a separate oil-level adjustment. However, please check your engine oil replacement interval before use. The effectiveness of the additive is directly related to the remaining lifespan of the engine oil; therefore, using the additive when the oil is already near the end of its service life will reduce the benefits, and the additive will be drained together with the old oil at the next oil change. For best results, add the product together with fresh oil during an oil change, or within 1,000–2,000 km after replacing the oil.

   Be sure to add the engine oil additive only through the engine oil filler cap or the dipstick hole, and do not use it for any other purpose.

5. [Transmission Oil Additives] What is the purpose of using a transmission oil additive?

   Because transmission oil has a much longer replacement interval than other lubricants, performance deterioration often leads to issues such as shift shock and slipping. These problems typically arise when hydraulic pressure inside the transmission drops, preventing proper gear engagement. The causes may include oil degradation, foaming, and the accumulation of sludge or other contaminants.

   Our transmission oil additive was developed to prevent or correct these issues. It is designed to mix with transmission oil, helping maintain its performance over a longer period. The additive breaks down and removes accumulated sludge inside the transmission, improves and stabilizes hydraulic pressure, and ultimately supports smoother shifting and proper shift timing.

6. [Transmission Oil Additives] Which types of transmissions can use this product?

   PowerDrag “Original” Transmission Oil Additive is compatible with all automatic transmissions, manual transmissions, and DCTs. The most important factor is to always use transmission oil that meets the manufacturer’s specifications. Using oil that does not meet the required spec can cause viscosity-related issues, including shift shock.
    

   Although the additive can be used in CVT transmissions, the performance benefits are relatively small, so its use for CVTs is not strongly recommended.

7. [Transmission Oil Additives] How should the product be used?

   The transmission oil additive comes in a 180 ml bottle and is designed to be mixed with 7–10 liters of transmission oil. However, unlike other automotive fluids, transmission systems are complex, and adding the product yourself can be difficult without understanding the vehicle’s structure. For this reason, we recommend using the additive together with fresh transmission oil during a scheduled oil change, with the assistance of a professional technician.

8. [Transmission Oil Additives] What effects can I expect after using the product?

   After replacing the transmission oil with oil mixed with the additive, most drivers first notice a reduction in noise, along with a decrease or complete elimination of slip and shift shock. (Actual results may vary depending on the vehicle model and the condition of the transmission.)
   As you continue driving, you may also experience improved cruising performance, which can contribute to better fuel efficiency.
    

   However, if these issues do not improve after using the product, the cause is likely not related to the oil. In such cases, problems such as gear wear or solenoid valve deterioration within the transmission are more probable, and we recommend having the vehicle inspected at a service center.

9. [Differential Gear Oil Additives] I hear noise from the differential—will the additive help?

   Because the differential is an independently sealed unit, any noise coming from it indicates an internal issue. There are generally two main causes:

   1. Worn or degraded oil that has lost its lubricating ability, increasing friction between the gears and creating noise.

   2. If this increased friction is left unaddressed, the gears eventually wear down, causing the noise to grow louder over time.

   In cases of actual gear wear, even changing the oil will not significantly reduce the noise, and the differential will require careful mechanical attention.

   Therefore, if the noise is caused by lubrication-related issues, the additive may help reduce noise.
   However, if the cause is mechanical wear or internal damage, the improvement will be minimal.

10. [Differential Gear Oil Additives] Can regular use of the additive help prevent gear wear?

    Yes. Differential gears operate under harsh conditions, requiring lubrication and cooling solely from the oil while temperatures can exceed 100–200°C. Because of this, differential gear oil oxidizes much faster than transmission oil, resulting in shorter replacement intervals and a higher risk of gear damage (wear) due to oil degradation.
     

    Differential gear oil additives help slow oxidation, extending the service life of the oil. They also provide excellent oil-film formation and minimize the coefficient of friction, reducing friction heat and improving overall thermal stability. With consistent use, the additive can help prevent gear wear, minimize power loss, and even contribute to better fuel efficiency and improved acceleration.
