How is the quality of KIVI engine oil?

KIVI Lubricants is a brand based in Singapore, one of the world's top three oil refining centers. KIVI Lubricants owns an independent petroleum production plant in Singapore. Below are the relevant introductions of the engine oil: 1. Reduce wear: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear of parts, it is necessary to establish an oil film of sufficient thickness between the two sliding surfaces to separate the relatively sliding parts, thereby reducing wear and extending mechanical life. 2. Cooling: Engine oil helps the radiator cool the engine by dissipating heat away from the engine. 3. Sealing and leak prevention: Engine oil can form a sealing ring between the piston ring and piston, reducing gas leakage and the entry of pollutants.

As a seasoned driver with years of experience, I've used Qiwei motor oil several times and found its quality decent, ranking at a mid-level. It's not a premium brand, but the affordable price makes it suitable for regular family car owners like me. My Toyota ran quieter after the oil change, and fuel consumption remained stable. When choosing motor oil, always check the API certification – Qiwei usually meets SN or SP grades, which are adequate for modern standards. Viscosity selection is crucial; for instance, 5W-30 suits most vehicles, so don't pick randomly. The synthetic version offers longer service life, while the mineral oil variant is cheaper. Recommended oil change interval is every 5,000 kilometers or six months – don't delay maintenance. Overall, Qiwei oil meets daily driving needs with good cost-performance, provided you purchase from authorized channels to avoid counterfeits. Remember, engine health directly impacts driving safety – regular maintenance matters more than any oil brand.

After using Qiwei engine oil for over a year, I find it quite cost-effective as an ordinary office worker. Driving a Volkswagen for daily commuting, the oil quality is decent and the price is affordable, saving me dozens of yuan each month. After the oil change, the car accelerates more smoothly without any shaking issues. The key lies in the additive formula—Qiwei has good cleaning capabilities, helping to reduce carbon deposits. Compared to big brands like Mobil or Shell, they offer better protection but are much more expensive. The synthetic version of Qiwei is quite durable, with the oil still clear after 5,000 kilometers. Driving habits matter a lot; Qiwei works fine for low-speed city driving, but for frequent highway use, upgrading the oil is recommended. Don’t forget to change the oil filter during maintenance, or the oil change would be wasted. If you’re on a tight budget, choosing Qiwei is a solid option—it’s reliable and keeps the engine running smoothly and worry-free. In short, for mid-range cars, mid-range oil is a reasonable match—balance is what matters most.

During car repairs, I've seen many vehicles using Qiwei oil, which meets quality standards and ensures the engine runs normally. The price is reasonable, making it suitable for economy models. The viscosity matches accurately, such as 5W-30, which is good for cold starts. The oil can prevent wear and resist oxidation, but don't expect ultra-high performance. Customers using Qiwei have no complaints, but don't exceed the oil change interval. Remember to check the oil level regularly to ensure safety.
