Oil additive f350. 7.3 2001
What is best oil additive to add to 7.3 with 171000 miles?
Forum Discussion
I put no additives in the oil of my '96 7.3. But in the fuel, I do use a dose of Power Service and a touch of 2-cycle oil intended to provide a little lubricity to the "dry" diesel being supplied nowadays.
The reason is that the process to remove almost all sulphur from diesel fuel has left it almost without natural lubricity. To compensate for this, the individual fuel jobber is supposed to add some lube to the diesel before supplying it to the fuel stations. The problem is there have been reports of fuel in various areas of the nation that tested woefully under-lubed, which can cause an abnormally high wear index factor when used in diesel engines.
I doubt this is an enormous problem when one considers all the various sources of diesel, most having adequate lube. However, the cost of my precaution is very little, and for that small cost comes the potential to help the fuel system remain healthy, especially the fuel injectors.
Sure the fuel additives add a few pennies per tank, but my 7.3 has never been to a mechanic since they put it together 21 years ago, and I'd like to keep it that way as long as possible. What little work the engine has needed so far, mostly routine maintenance and a replaced radiator and water pump, I've been able to do myself.
The costs of ownership for my old 7.3 has been relatively small. I believe I paid around $26K for my F250 when I bought it new off the lot 21 years ago. I think I could sell it for at least half that right now if I suddenly went insane.
That's my story, and I'm sticking to it.
