Many years ago tranny fluid in the fuel worked pretty well. Now the tranny fluids have changed a lot and so have the diesel fuel systems. I wouldn't use it and particularly in a VP-44 engine since the IP is so sensitive to being lubricated properly through the fuel itself. JMHO.

yes people have used ATF, however it is not good for the engine...ATF is not ashless, therefor it will build up quite a bit of carbon deposits on the injectors, valves, exhaust manifold, and turbine and turbine housing on your turbo.

that is why I only recommend ashless 2-cycle oil...and as far as the 2-cycle oil goes, do NOT use it on a 6.7L truck that has not had EGR and DPF deletes. if the deletes are done then it's fine to run, but with DPF and EGR in place it will clog up the intake and DPF faster.


yes 1oz per gallon or 1qt per 32 gallon fillup.

info of what works, how well it works, and what doesn't work...

also note I recommend a stronger mix of 2-cycle vs what was tested on the chart...

as a update on the fuel mileage cleaned the iat and map sensors upgraded from factory airbox and fiilter to a bhaf and ran my edge on 5 on the same trip i avgeraged out at 14mpg but that still isnt the 18 to 20 everyone talks about
did not have a chance to try the 2 stroke oil though planing that on the next tank

You're probably not gonna see 20 with lift and big tires :c:

get a smarty. It can correct your speedo for tire size

I have been using atf for 5 yrs in both of my truck ( 87 f-250 7.3IDI & 95 12V ) ... no issues and I have the 7.3's heads off and thier real clean ..... was super suprised ... i can post pics ...

My friend has an 04 5.9l and I noticed the same thing if he ran his edge n stage 6 he got about 19.2. Another guy I noticed in his 2000 wasa getting about 22mpg. He had 35s levaling kit bigger injectors and a edge comp box or what ever it is called. I was just thinking about putting 150hp injectors in my 02 cause I heard it will help with millage but I got a warranty from the dealer for 5 years so i may have to wait. Also I did see an improvement when i bought my truck in January I was getting 11mpg then. Got a superchips tuner for cheap and seen my mileage jump to 14 then I got a straight pipe 4in I jumped to16. Also I found out my fuel gauge is off at 1/4tnk I'm empty so idk if this affects my average reading on the gauge

I get 22 on hwy level 3 and fuel on 5

boost leak? dragging brake?

you can use new tranny fluid as a lube I run a lot of used power steering and tranny fluid in my fuel like 12 gals or so at a time its filter then goes into my ttruck I have a fass twin set up so it gets filtered good it does smell like shit and blows white smoke at idle if you run it right its not bad I do about 70% tranny and 30% fuel in summer does good!
