Well guy, it is all "hearsay"! It's your friends car. How do you know how he drove? How do you know he correctly measured the amount of fuel used and the miles driven. It's all off the cuff and is a worthless question. Like Diesel Doc says, typical normal mileage on a 300D starts at about 22 mpg. To get into that 25/28 mpg you have to be a real achiever and everything has to be done really right. They are a heavy car and not really good mileage makers in the current era of high fuel costs. Back in 77 to 1985, they looked a lot better for mileage.
