I’m getting some lousy mpg around town in my 99 e300. I resealed the fuel system, it has no leaks. No dragging brakes, no bad wheel bearings. I’m getting 17.5-18mpg around town. 221k. Original injectors. Well maintained car. Does sound a bit clattery even after it’s warmed up. Makes good power little smoke.

I do a lot of short trips making sure it gets up to temp. With my now job, I work about a mile away from home, so all in all weekly I’ve got a 10-15 mile radius. Is it possible that’s why it gets such low mpg city? I’ve had a few of these and remember better mpg. I use quality fuel too.
