what kinda mpgs
What kinda mpgs should i be getting with my 4x4 727 auto cummins. Smoke screw is in 1great turn and star wheel is down roughly 1.5 turns. I run diesel kleen in every tank. I drive it between super fuel save mode and foot to the floor. Ive filled twice and got roughly 11.5 mpgs. I think i got a injector knock that i notice going thru drive-thrus. Would that cause my mileage to go down?

What size tire and wheels do you have??????
|
33x11.50x16.5. Rims are aluminum
|
I'd say that might be knocking the mileage down some, what was it before you got 11.5 MPG?
|
Starwheel turned down and smoke screw turned in will give you no power gain, just smoke plus hurt your mileage.

It doesnt smoke at all unless i lay on it. I've had the truck for a month. When i got it the starwheel was all the way in, smoke screw was all the way in, and fuel pin at its deepest setting. I got 11.69 mpgs with those settings on the first tank. I backed everything out. 11.5 mpg the second tank.
---AutoMerged DoublePost--- I bought the truck figuring it would match the mpgs of my old 1990 chevy k1500 350 auto which was a hair over 16mpgs |
My dually with a turned up pump and auto trans gets 17mpg with a heavy foot. Have you changed the oil, and fuel filter?
|
I get almost 22 with my dually. Those size tires are hurting you for sure.
|
I changed the fuel filter . I dont see how 33's would affect my mileage that much
---AutoMerged DoublePost--- Pretty sure om getting air in the system |
You should be getting over 15 no matter what. Look for white soke under acceleration, that would mean air in the system. I'd start by running a bottle of diesel kleen through, always works wonders for me.
16-19 mpg is what I'm getting out of my 12 valve |
