Does anyone know just what the "LPX" is in the M-Pro7 Gun Oil LPX? I happen to have two small bottles, one is older than the other, one is relatively (past couple of years) newer. Both products are somewhat milky-greenish (for lack of a better term), the newer one is a little less viscous. I did read somewhere that they changed the formulation several years ago. Nowhere on the website (or any of the old press releases from when they introduced the product), could I find any indication of what this LPX is supposed to be. Their SDS has no ingredient listing, however I did find an MSDS on Brownells.com website that lists three things: synthetic oil, tritoyl phosphate, distillates petroleum hydrotreated paraffinic. Their website has these two blurbs about the product: Combines high quality synthetic oils and LPX additives, Formulated from technology with the lowest known friction coefficient.

So my question is: What is the LPX? Is the LP liquid polymer? What has "lowest known friction coefficient?" Does that mean they use PTFE?

PTFE is close to or equal to water on ice which is about as low as it gets.

Hard to tell what they are using but I do know that DuPont has stated that Teflon has "no significant benefits as an engine additive."

*M-Pro7 LPX is a "Lube / Protect" versus a : "Clean / Lube / Protect" . It is a very fire arms gun oil ! The PTFE is most likely Teflon which while some may have an issue with for EPA reasons - I don't mind as you use and leave so little of it on firearms and it makes slide grooves very slick . Clean firearms first with a good cleaner or even a CLOP and then use the M-Pro7 LPX last in / on all the key lube areas .
