I neglected to mention that ANY METALS in the fuel are bad news long term. We have to add metal deactivation compounds in ACES IV to deal with the normal copper and vanadium that is inherent in the fuels that cause gum, varnish and deposits.
Ferrous Picrate, Ferro organo metallic complexes , any copper, platinum, cerium or rhodium products in any form should be avoided. They cause such problems that we had to independently test ACES for all of these metals as no metals are allowed if you supply a fuel additive to the military for military vehicles:
AL,Sb,Ba,B,Ca,Cr,Cu,Fe,Pb,K,Mg,Mo,Na,Ni,P,Si,Ag,Sn,Zn,Sr,V,Ti,and Cd all below 1 ppm!
The additives that contain these are also acidic and cause problems with your oils as well.
These are the facts even though there may be people here that are presently fans of them!
