Used to get 17 mpg on a good day stock. Now with EGR deleted, Kennedy air box mod, banks exhaust turbo back, EFI live tuning by Idaho Rob, 5 to 6 speed tranny conversion (about 1mpg increase average), intake horn mod, stock tire size, nicktane prefilter, and lift pump, I can now get 20-21 where I could only get 17-18 before.
As far as 2-cycle oil is concerned, I never ran it with my first set of injectors...only some stanadyne...and got 112K miles out of them. On the 2nd set I ran 2 cycle oil in every tank and only got 56K out of them. For the 3rd set I am not running any 2 cycle oil but running stanadyne in every tank. Personally I think running 2cycle oil, at least for me, was a waste of money and time and seemingly did nothing to extend the life of my injectors. The truck currently has never run so well.

Fuel mileage? Who cares, its a diesel.
