    i was getting some diesel the other day and i saw they had a bottle of diesel additives, like fuel additives.. i didnt know that these things existed.. i looked at it and it said it was good for a 14 gallon tank.. well my tank is 31 gallons. do they do anything? should i spend the $2 on them ? just wondering the effects of them..

    I run Stanadyne Fuel Conditioner in my 83 all the time, but my 83 6.2 was orginally designed to run on sulphur-rich fuel. Nowadays the all of the diesel avalable in my area is low sulphur, so to ensure that my pump gets the proper lubrication I have to run an additive.

    I'm not sure if it would apply to your motor- what year is your 6.5? Maybe GM changed the way the injection pump got lubed by the time your motor was built.

    The other advantge to running a quality additive is that it's designed to keep your diesel fresh and *should* break down any water in your tank. In my case the Stanadyne also lowers the point at which diesel starts to wax up(if you live in a warm climate you don't have to worry about this) so I don't have to worry about driving at extreme low winter temps. It should also contain an injector cleaner to keep your injectors clean.

    I would use the additive anyway, it doesn't hurt the egnine, it makes it run smoother.
    I use it more in the winter times but I put some every few fillups, just because I forget.
    I do feel the difference between when I run it with the additives and when I run it without.
