After reading this thread it inspired me to go hunt for some nicer oils. Bought 4 different kinds at my local gun shop, picked up a small bottle of clp break free, slip 2000, mil-comm (mp2500 i think) synthetic gun oil with the nra endorsement, and the mil-comm extreme performance synthetic grease. After trying out all of them if come to favor both the synthetic oil and grease. Cleaned out the domino and tried the grease and i wont go to oil for my bearing knives, although i have the synthetic oil in my 801 and it is smooth as butter but i will switch to grease next time i take it apart. For all my washer pivots i noticed a difference (improvement) when using the synthetic oil from clp or hoppes. Still cannot get my lionspy to the smoothness id like but oh well
Bottom line i would recommend the mil-comm synthetic products for sure. Says they don't collect sand and grit as much but only time will tell . Some very good info in this thread!
