I have a 2014 GLK 350 (2WD) that is supposed to hold 7.4 qts of oil per the owners manual. I drained the oil the old fashioned way (drain Plug) and installed a new filter then added 7 qts of oil. After running it for a few minutes it registers above max by 1/4 inch. After driving it 20+ miles and letting it sit overnight it still registers above max. If I were to add the additional .4 qts it would be about 3/4" above the max. The dipstick in it has the Mercedes emblem and A27618 on the top and no other information. I bought this used from a dealer but do not trust that the incorrect dipstick may have been installed. Can someone with a 2014 or 2015 GLK 350 measure the dipstick from the end of the red plastic to the bottom of the green cap so I can compare with mine? Thanks in advance.
