2005 Mercedes-Benz CL65 AMG: Checking and Adding Oil
January 9, 2014
Before heading out on a road trip, it's always a good idea to do a simple spot check of your car, especially an older and infinitely complicated one like our 2005 Mercedes-Benz CL65.
Checking the oil in the CL-Class is not as simple as pulling out a dipstick. Instead, the car does it itself upon your command by way of the gauge-mounted trip computer. Unfortunately, this did not work for me. When I went to the oil check screen it told me to turn off the engine. When I turned off the engine, it told me it couldn't check the oil with the engine off. Um, make up your damn mind you crazy car. A reading of the instruction manual seemed to tell me to do exactly what I was doing.
So, I just assumed everything was OK and knew that if it wasn't, the car would tell me. Guess what? After about 200 miles into my drive to Las Vegas and the Grand Canyon, the CL ordered me to "Add 1.0L of oil at filling station."
Very well, sir. I popped into a Las Vegas Autozone, bought 1 quart (0.946L would have to do) of the car's required Mobil European Formula 0W-40 and fed the beast.
Perhaps I was doing it wrong. Perhaps there is something wrong with the oil check system. Something to look into either way, but at least the car knows what it needs and when it needs it.
