Semi-synthetic oil is a lubricant formulated from Group III base oils, which are refined from mineral oil through hydrocracking technology. Specifically, it is a blend of mineral oil and full synthetic oil in a 4:6 ratio, with the addition of certain additives. Additional Information: 1. Semi-synthetic oil is generally suitable for mid-to-low-end naturally aspirated engine models. As long as it is not a turbocharged engine or a high-end, large SUV model, semi-synthetic oil can be used. 2. The replacement interval for semi-synthetic oil is around 8 months, typically requiring a change every 7,000 kilometers. 3. There is no fixed replacement period for engine oil; it should be determined based on actual driving conditions and habits. If the driving environment is harsh, the oil should be changed earlier. Additionally, the type of oil used should also refer to the recommendations in the vehicle's maintenance manual.

What is the fuel tank capacity of the Camry?

The Camry has a total of 10 models currently on sale. Among them, the hybrid versions including the 2.5HQ Flagship, 5HGVP Leading, 2.5HS Sport, and 2.5HG Luxury have a fuel tank capacity of 49 liters. The remaining models have a fuel tank capacity of 60 liters. These figures are officially released data. The Camry uses 92-octane fuel. The hybrid versions (2.5HQ Flagship, 5HGVP Leading, 2.5HS Sport, and 2.5HG Luxury) have a fuel consumption of 4.1L per 100 kilometers, allowing a driving range of 1,195 km on a full tank. The other models have a fuel consumption ranging from 5.5L to 6.0L per 100 kilometers, providing a driving range of 1,000 km to 1,090 km on a full tank. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. Under normal circumstances, the fuel level is accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel added may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safe fill level, leaving some space from the safe fill level to the tank opening. This space accommodates fuel expansion due to temperature increases, preventing overflow. If fuel is filled up to the tank opening, the actual refueling volume may exceed the marked capacity.
