MB-Convert,

The owners manual incorrectly states that the fuel tank capacity is 18.5 gallons. The E300D came standard with the 18.5 gallon tank from the factory, but MBNA ordered the cars with many otherwise extra cost options (a usual practice) which were standard equipment for the U.S. market including option code 915 (fuel tank with increased capacity) on the E300D but didn't change the specs in the manual to reflect this.
