In other words, it drives like the day it left the proverbial showroom floor. Yet, the best fuel economy I can manage is barely 21 mpg for pure highway driving. Around town and in the winter it's around 18 mpg or even less. :(( Are there any engine adjustments to improve fuel economy? I would gladly sacrifice some power to improve this by 2- 4 mpg. The tires are normally inflated and I drive conservatively. The car has a replacement transmission from a 1985 300 turbodiesel, if that's relevant. By contrast, my 1985 300TD achieves 26 mpg on the road. :) Whoever comes up with a working solution that doesn't cost an arm and a leg wins a box of organically heirloom tomatoes or peppers (or both) delivered free to any address in the lower 48 states.
