AWW$HEEET Posted April 10, 2011 Report Share Posted April 10, 2011 What are you duramax drivers getting on mpg, and what is diesel running right now per gallon? Quote Link to comment Share on other sites More sharing options...
RS69 Posted April 10, 2011 Report Share Posted April 10, 2011 I just bought mine a couple of weeks ago and I got 17 mile per a gallon averaging 85 miles per a hour down to KY. The last tank with normal speeds, mostly city was 15 miles per a gallon. I just paid 3.99 a gallon in Sunbury. Quote Link to comment Share on other sites More sharing options...

RS69 Posted April 11, 2011 Report Share Posted April 11, 2011 my LLY got 22mpg with no tune. Have you done any mods on yours, such as the mp? Thanks, Rick Quote Link to comment Share on other sites More sharing options...
AJ Posted April 11, 2011 Report Share Posted April 11, 2011 i traded it off when we sold the boat. i never did any mods to it. note on duramax trucks. the older ones (02-05) you are supposed to change the fuel filter every 14k miles. the red spin on transmission filter every 7k miles. the fuel filter is extremely important that you do it every 14k if you have a 02-04.5 LBZ.
