Unleaded 91 was replaced by Super 95 due to the increasing demand for higher octane fuel in modern vehicles. Super 95 has a higher octane rating, which means it is more resistant to engine knocking and can provide better performance for high-compression engines. Additionally, Super 95 may also offer better fuel efficiency and lower emissions compared to Unleaded 91, making it a more environmentally friendly option. As a result, many car manufacturers now recommend or require the use of higher octane fuel, leading to the replacement of Unleaded 91 with Super 95 in many markets. **

To determine if someone is overweight, we can calculate their Body Mass Index (BMI) using their weight and height. For a person weighing 81 kg and with a height of 176 cm, the BMI would be calculated as weight (kg) / height (m)^2. In this case, the BMI would be approximately 26.1, which falls into the overweight category according to the World Health Organization classification. Additionally, a waist circumference of 91 cm is also considered high and may indicate excess abdominal fat, which is associated with health risks. **

Based on the information provided, it is difficult to determine if the individual is overweight without knowing their body composition and muscle mass. However, we can calculate their body mass index (BMI) to get an idea of their weight status.

Additionally, a waist circumference of 91 cm is also considered to be in the overweight range for men. Therefore, based on this information, it is likely that the individual is overweight. **
