just got a 1988 f250 7.3 na with 150000 miles runs good i got it from a guy who has never ran any fuel treatment in it ive had a couple chevy diesels an i always ran atf in it so iam wondering should i use atf or 2 cycle oil in it or just not treat the fuel an help here be appreciated

 

I use PS diesel kleen and mine runs better and quieter.

 

i use stanadyne and love it

 

I use ours, but anything is better than nothing. Diesel fuel quality varies all over the board....plus a little lubrication with today's fuel is a good thing.

 

howes is a very good additive, same with stanadyne. one of my issues with PS(power service) is they all have alcohol in them. u can smell it in the bottle it is so strong.

 

i run lucas in my truck
