Oh boy,, Your going to get 76 different favorite oils,
I decided on MILITEC and it has worked very well. I will have to say, mobile 1 synthetic is also outstanding.
There are oils not to use BUT,,,,,,,,,,,, there really are NO miracle oils. The synthetics seem to stand out above the rest.. Theres a PLATE of truth test on the INTERNET.
It subjects a plate that is divided up into test blocks to harsh enviormental conditions. The blocks are treated with different GUN OILs. The results will tell you
WHAT NOT TO USE!!!!!!!!!!!!!!!!!!!!!!!
