I have a complete stock 2001 7.3 sc 4x4 and it only gets 13.5 mpg!
you need to do two things... add lubricity to your fuel... run B20 or see this thread poke here
and add a cetane booster

Thank you very much for the info! I read the link to the previous posts and have a couple questions. Do you run both the cetane booster and the TCW3 outboard oil together or at different times. Also a super newb diesel question! How can i tell what type of diesel fuel i am buying. Example: B5, B20 and so on. Also, is all diesel fuel that is sold today from a basic gas station ULSD? Thanks!

I get 12. All I ever got was 12. Stock was 12 and now mod'ed is 12. I use Stanadyne with every fill-up. B20 got me 12. I've kept a chart of the last 18 months, and it has all sorts of driving in it. I wish I knew why I can't get better.

I wish...lol... 
but it's a simple miles driven/gallons used calculation. I think there was a mileage thread posted a while back where I shared the file. If I think to do it, I'll look it up.

yes, run the TCW3 and the cetane booster at the same time IF you are using ULSD... if you have access to bio (which has to be labelled as such on the pump), use it and a cetane booster... no need for the lubricity of the chainsaw oil..
