What is the difference between Total 8000 and 9000?
2 Answers
The difference between Total 8000 and 9000 is that Total 9000 is a full synthetic oil, which is better than Total 8000, has a longer oil change interval, and offers superior high and low-temperature performance. Additionally, Total 9000 is more expensive than Total 8000. Mineral Oil: Mineral oil is the residual oil left after gasoline and heavy oil are extracted from petroleum. Although it is a natural oil, it contains more impurities. Compared to semi-synthetic and full synthetic oils, it is cheaper, provides poorer lubrication for the engine, and has a shorter service life. Semi-Synthetic Oil: Semi-synthetic oil falls between mineral oil and full synthetic oil. It contains a significant amount of anti-corrosion additives to enhance the oil's stability and oxidation resistance. Full Synthetic Oil: Full synthetic oil is the highest quality and most durable among the three types of oil, and it is also the most expensive. Generally, it can maintain its quality for 10,000 to 12,000 kilometers in typical passenger cars.
Total 8000 is a semi-synthetic engine oil, while the 9000 is a fully synthetic formula. The 8000 is more affordable, making it suitable for daily commuter cars, but its high-temperature performance is slightly inferior. The 9000 has a more stable molecular structure, making it ideal for turbocharged engines or drivers who frequently travel at high speeds, as it can withstand higher engine temperatures and maintain viscosity better during prolonged high-RPM operation. In terms of cleaning performance, the 9000's dispersant formula is stronger, effectively reducing carbon deposits. Several decade-old cars I've serviced showed noticeably reduced noise after switching to 9000. There's also a clear difference in longevity—the 8000 typically needs replacement at around 7,500 kilometers, while the 9000 can last over 10,000 kilometers under good conditions. Although the 9000 costs 30 yuan more per liter, it actually offers better value when calculated per kilometer.
