Hello,
We are doing some testing of Jet A and the issue came up of additives. Our vendor tells me that a product called diethylene glycol monomethyl ether is added to the fuel to enhance the fuels lubricity, but he doesn't have any details on this.

Per ASTM D 1655 and D 4171:
diethylene glycol monomethyl ether is added as a fuel system icing inhibitor.

Pratt and Whitney have a Service Bulletin whose number escapes me at the moment that gives dosage levels for a lubricity enhancer called DCI4A. It is actually a corrosion inhibitor primarily but does "up" the lubricating properties of the fuel as a by product. The dose levels are so small that it is only detectable by performing a wear scar test or a rust test. We have not found a way to detect it, let alone measure the concentration in our fuel in the field.
Hope that helps.
Oh, DCI4A is made by a company called Innospec (used to be Starrion I believe).
