i have not been getting good mileage for the past couple of months now...i am only getting about 330 per tank...that seems unusual for a diesel, even if it weighs as much as mine...

injectors seem good as the engine does not shake and was told that bad injectors would cause engine shaking...

also, ran diesel purge as well as other injector cleaners through and NO difference...

any suggestions???

thanks in advance...
