'85 190D auto gets between 34-38 mpg's. I wonder what the improvement would be with a 5-speed? My son has an '87 190DT and ranges from 27-31 but he's know to have a heavy foot. Your 190E gets 25. Diesel is 10% - 15% higher so my RUG adjusted mileage is around 30-33 if you buy at the pump. You can always explore the alternative fuel supplies but lots of folks warn against?
