Fueling up the tanks and airing up the tires for a road trip. Years ago they removed most of the sulfur from our diesel, giving us Ultra Low Sulfur Diesel. Well, that sulfur was one of the primary lubricating factors which kept the insides of your injection pump from wearing. Diesel fuel itself is the actual lubricant for almost every internal part in almost every kind of diesel injection pump. So when they removed the sulfur, they increased the potential for premature wear in all pumps, especially the older ones.
Now while I am still researching the very best additive to use to get the lubricity (lubricating factor) back into my fuel .. I am currently using Diesel Kleen with Cetane Boost, mostly because it's available in almost every auto parts store and I have not discovered any reason not to use that particular brand. Folks say that the Stanadyne product may be superior, but you almost always have to special order the Stanadyne additive.
So I may switch to another additive and it might be Stanadyne, but for now I have no issues with the Diesel Kleen by Power Service.
I have measured a 10 to 15 percent increase in fuel efficiency when using the additive, which easily pays for the additive itself. It's the Cetane-Boosting aspect which increases your fuel mileage. Similar to an octane Boost, in a diesel engine, a higher Cetane value means your fuel vapor can start compression-igniting a little bit earlier which results in more fuel being burnt more efficiently, hence more power and better mileage.
I believe there are also detergents in this and other additives which helps to keep the fuel system and injectors clean.
Lucas Oil (upper cylinder lubricant) vs. Diesel Kleen (gray bottle)
My results front using Lucas Oil Fuel additive:
AVG: Normal daily driving - 16.8 55 Mph freeway w/cruise
control - 24
ADD: 6oz per fill up (23.8 - 27.7gallons)
1/10 Mile test: 10.3 seconds @ 67 MPH
EGT: 1,500 Outside temp: 85
Results from Diesel Kleen (gray bottle):
AVG: Normal daily driveing - 18.0 55 Mph freeway w/cruise
control - 23.3
ADD: 8oz per fill up (23.8 - 27.7gallons)
1/10 Mile test: 9.7 seconds @ 72 MPH
EGT: 1,400 Outside temp: 83
The biggest difference I saw was with MPG and more responsive throttle. Im
thinking of doing testing with more cetane increasing formulas to see what
I can get going.

12 Valve Cummins towing heavy
This is a my 1994 Cummins hauling a load of firewood back from Centre
County running through the rock cut on I-80 east bound around mile 179.
Total weight was about 18,700-19,200 LBS. about 203800 and still running
strong. May trade it on a 2007 6.7 Auto... Any advice?
