Default Re: Anyone Know or have experience with a Diesel Conversion?

I have a 2005 chevy 2500HD ext cab 4x4 with the Dmax/Alli that I bought new in 2004 and I never got better than 16 to 17 MPG and now I a'm getting 15 to 16 MPG . if you do the Diesel swap you will have much better power but don't expect more than 17 mpg . you will also need the transfer case with the Dmax/alli conversion. I don't know if the cost is worth it ,but everyone has an opinion and that's mine. my 03 Hummer h2 gets 12mpg but I only use it to go off road so it ain't that bad.
