Diesel fuel additives for 7.3

[BR'sCrewCab]

I have been researching fuel additives and wanted to get some opinions from everyone on what they have been using and experience with different products?

When I used to run it, I liked Stanadyne Performance Formula. Whatever you decide to run, make sure it does not contain alcohol. Cheers!

I have been using Stanadyne Performance Formula for about 20K. Before that I used the Motorcraft Cetane Booster. Both are good but I've herd so much good about Stanadyne that I feel better running it. Basically Stanadyne makes diesel injection systems and they couldn't find a additive that met their standards so they made their own.

Is there a reason you no longer run it?

I run silver and white diesel kleen. I try to run the white when its expected to be very cold, but overall I run them about the same just because they are way better than to not run anything. I also run an ounce to gallon, of tcw3 outboard two stroke motor oil. It is ashless and really quiets down the injectors.

I stopped running it just due to the added expense and it's not as easy to get as some of the others (I used to get a case at a time). Cheers!

I found a local distributor for Opti-Lube XPD Fuel Additive. I am going to give a gallon of that stuff a shot.

Good choice bud. From what I've heard walmart did an on the road study of various types of additives. They chose diesel kleen because it kept wear down, and helped mpg some. I haven't noticed any mpg gain, if anything an mpg loss but that could be do to variance in idle time, driving factors etc.

Currently running Howes Diesel Treat. My local parts store had it on sale the last time I as in so I grabbed a bottle. Believe I paid $12 for 64oz, so it was considerably cheaper than the Diesel Kleen I usually run.
Haven't noticed a considerable difference between the Howes and Kleen. Truck idles the same, sounds the same, and is pulling the same mpg. One thing I have noticed however is less smoke on cold starts. Not sure if this is due to the additive or slightly different temperatures.
