getting bad gas mileage.
Hey,
I am getting 12-16 mpg in my 03 Cummins, just over 200k. I have changed the air and fuel filters, put fuel rail cleaner through it, cleaned off the ait and map sensors still got about 3k miles before i need to change the oil and im not getting any fault codes on the obd2. I dont know what to do at this point i do have access to my own obd2 so i need to take readings just let me know. Any help would be appreciated.

I dont understand what you mean. Run the valves like just running the engine or what. Are you talking about tracing a fuel leak in the last part or what.
