fuel additives

If you drive in colder areas where they switch to #1 diesel in the winter, then you need it during the winter. To make #1 diesel so it flows better (doesn't turn to slush) in the winter, they take some of the wax out of it which in turn takes the lubricity out of it which in turns means you can loose your expensive injector pump.

When running #1 fuel, use the additive. If all you run is #2 fuel living in a warmer climate, then don't worry about it.

Does your diesel manufacturer recommend additives?

Not me, but I've never used that kind of stuff on anything. It's always just seemed like a waste of money.

Seems alot of the Powerstroke guys think they need additives to save their engines...
Unless there's a problem you're trying to cure or you bought the wrong fuel for the weather, there is no need to add anything but diesel to your diesel tank.
