1991 740 auto sedan with 157,000 miles on it. For past couple of weeks I have checked, cleaned, and replaced everything I and Brickboard could think of in an attempt to improve my bad gas mileage(16 around town 22 highway). However no improvement. At this point I think I give up and am resigned to poorer mileage then I had been expecting. Previous Volvo's I have had did about 18 around town and about 27 highway. Then again they had Bosch fuel system whereas this car has Regina system which I have never had before. Maybe Regina system just doesn't deliver as good a mileage as Bosch system ??? What if any are positives about Regina system versus Bosch ???
