What is the engine oil specification for the Mercedes-Benz E300L?
1 Answers
Mercedes-Benz E300L's original factory engine oil is Mobil 1 Gold, with the specification 0W-40. For later maintenance replacements, you can choose international brands like Shell and Castrol, or well-known Chinese brands such as Great Wall, Tongyi, and Tianshan. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The second number represents the oil's kinematic viscosity at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Mercedes-Benz E300 is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain; Use a special wrench to remove the oil filter; Apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add new engine oil through the oil filler cap on the engine valve cover. Generally, fill up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, then check for any oil leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
