Dancing Fuel Guage
As I have posted several times before, this has also been my experience and I attribute it to contamination in the fuel the makes the fuel sensing unit read inaccurately. I have used Exxon/Mobil, ETNA, Kangaroo and Hess gasolines with no problem. For some reason, BP causes inaccurate fuel gauge readings in both my 1995 C280 and 2000 ML320. Due to this reason have not used BP fuels in my vehicles for the last 3 years.
