Earnings for truck drivers can vary greatly depending on experience, type of driving, schedule, and location. According to the U.S. Bureau of Labor Statistics, the median annual wage for heavy and tractor-trailer truck drivers was $47,130 in May 2020. However, drivers working for private fleets, like those of retail companies, usually earn more. In contrast, beginning drivers and those operating in certain regions may earn less than this median amount.
It's best to check engine oil when the car is cold, ensuring accurate readings. Cold, in this context, means the engine has not been run recently and has had time to cool down, typically after being parked for several hours or overnight. This allows the oil to settle in the oil pan, avoiding skewed measurements due to oil circulating and coating engine components during operation. If checking when hot, components might be too warm to handle safely, and oil hasn't fully drained back into the pan, potentially leading to inaccurate readings. Moreover, checking in a consistent state, like first thing in the morning, offers the most reliable measure of your oil level, helping you maintain your vehicle effectively.
The first diesel engine was invented by Rudolf Diesel, a German engineer, in the late 19th century. Rudolf Diesel was granted a patent for his invention on February 28, 1892. His innovation stemmed from a quest to improve the efficiency of steam engines, which were the predominant source of industrial power at the time. Diesel's engine was designed to convert the chemical energy of fuel directly into mechanical energy through the combustion of the fuel inside the engine itself, a process known as internal combustion. This was in contrast to steam engines, which rely on external combustion. Diesel's engine proved to be more efficient, particularly for high-power applications. It first ran successfully in 1897, and due to its efficiency and reliability, it quickly found applications in a wide range of industries, including automotive, marine, and railroad sectors.
