Additives
Since I have been reading in this forum I have come to the conclussion that older diesel engines require a variety of additives. One for the water in fuel, one for the lack of sulpher in modern fuels another to lubricate the cooling system & a couple more that I don't remember right now. Isn't there one product that will do all of these things? If not I think that I will invent one.

I have been adding a mix of Diesel Tone and Howie's to my recently purchased 91' F350. The truck only had 30,000 mi on it when I bought it but never had seen a drop of additive in its entire 14 years of life.
I notice little changes every morning in the way it starts better, little better power when I climb the local hill and the white puff of smoke on start-up has almost completely cleared up now.
Can't overdo it with the additives. Be patient it will take a couple of tank full to get the fuel system back in shape, especially after it has been neglected for a long time.
Just in the last couple of days it now starts to fire on the 3rd or 4th compression stroke where it used to take up to two full engine revolutions to get the first cylinder to fire (with glowplugs fully functioning). Also used to get a puff of white smoke once she fired when I first got the truck. At the current rate of recovery, I figure she will fire on the first compression stroke in two to three weeks or so.
Diesel Tone, Diesel Kleen, Howie's, or the Stanadyne Formula, they are all good in my experience and are worth the money, no doubt about it.
I also noticed that it also helps to get the engine revs up (3,000 rpm) once in a while after you got the fuel additive going to clear the IP and injectors of any crude the additive has loosened up.

My dads 92 7.3l with the E4OD regularly used to start surging as the govenor starts to stick because he had not used the fuel additive for a while.
A fuel additive for a week or so and she is usually right back to normal.
I have noticed surging can be a problem more on automatics than standards, not sure why.
