diesel additives
when ever i use a diesel fuel additive i get around 12 to 13 mpg highway but if i use none i get around 16. i deleted my catalytic converter, k&n airfilter, wickedwheel compresor, and a superchips tuner for my 2001 f350 anyone else get this problem?

How long have you went without the additive? Because I notice a pretty good change in MPG when I use it for about 3 fillups in a row, then on the next one that I don't use it on...I get good mileage...

i can tell a big difference with 16oz of Diesel Kleen per fill up. i hear that the Lucas additive is good stuff. i get a 2 to 3 mpg boost with DK. what kind of K&N filter do you use?

the reason i asked about the k&n filter is because it can raise the silicon levels in the oil on Oil analysis reports. Several people here run the Quik filter (6637). with great results. it gives our trucks all the air it needs and keeps the oil clean. in dusty conditions i would recommend the ford AIS intake. awesome free flowing heavy duty intake. didnt mean to hijack the tread.
to get back to your mpg issue with lucas, how often do you change your fuel filter? the lucas additves might be really cleaning out your tank and lines and it ends up in the fuel filter! i know when i started to use DK i had to change mine twice in 3000 miles!
