How to Check the Engine Oil Level in a 2019 Mercedes-Benz E300L?
1 Answers
This model does not have a conventional dipstick. The oil level is displayed on the dashboard. After maintenance, check the oil level on the dashboard, which should be controlled between the upper and lower marks on the dipstick. Excessive lubricating oil can escape through the gap between the cylinder and piston, entering the combustion chamber and forming carbon deposits. Here is extended information about carbon deposits: 1. Carbon deposits increase the engine's compression ratio, increasing the tendency for knocking: Carbon deposits in the cylinder can become red-hot, easily causing pre-ignition. If they fall into the cylinder, they can accelerate wear on the cylinder and piston and also speed up the contamination of the lubricating oil. 2. Excessive lubricating oil increases the stirring resistance of the crankshaft and connecting rod, increasing fuel consumption: Naturally aspirated engines have relatively general requirements for oil quality and can use mineral oil and semi-synthetic oil. 3. Use full synthetic oil: Compared to naturally aspirated engines, turbocharged engines have more precise internal structures, harsher working conditions, higher-grade lubricating oils, and better fluidity, so it is best to use full synthetic oil.
