I presonally use Lubrication Engineers products as I have found none better in the last 25yrs, this is the additive I use.
Hey, I've been using LUBE CONTROL LC-20 for nearly 40 years, off and on! FP-60 FUEL POWER has been good to me in diesel and gasoline vehicles (consistency).

LE was practically next door when I lived in DFW.
And, I guess we both value SCHAEFFERS
Schaeffer Oil | Diesel Fuel Additives, Conditioners, Treatments
I hear good things about their diesel soy fuel additives but haven't yet tried them (from a tribologist and others).
The one I ALWAYS recommend from their line is CLEAN & COOL #258 (as many already understand that their grease and lube oils can't be beat for value).
To the OP: SCHAEFFERS is carried by some NAPA stores now if interested. Main business of America's oldest oil company has always been industrial and agricultural. Truckers know them, too.
