1993 D250 My mpg was 20 now its down to 14 to 15 mpg. Took a trip down Baja . Before going I asked Cal Cummins if there was any problem using Mexican diesel . No problem was the answer . I noticed the change with the first tank full, only in milage. The trucks preformance didn't change. Had Cummins check it out, the pump & injectors they were ok. Trans check out ok. What else could it be ?
