2005 Mercedes-Benz CL65 AMG: Needs More Oil
December 8, 2014
Once again, our long-term 2005 Mercedes-Benz CL65 AMG is asking for a liter of oil. Since this is something we've come to expect in the CL65, there was already a quart (0.946 liters) of 0W-40 waiting in the trunk when the warning light came on. I bought a replacement quart but I also wondered how much oil the CL had gone through in the last eleven months.
Not including oil changes, the CL has burned about seven quarts of oil over 14,481 miles. The rate at which it burns oil seems to be related to driving style, with larger intervals happening when the CL goes on long, cruise-controlled road trips and shorter intervals coinciding with lots of city driving.
The CL65 can seemingly go thousands of highway miles without needing any oil, but if you've got a heavy foot and you spend a lot of time in stop-and-go traffic, it will ask for oil as often as every 500 miles.
