anyway if you run a gun hot enough ATF will catch fire. synthetic oil wont. plus ATF has very little lubrication properties.
I use Mobil1, it's great stuff. I always use ATF, but I never ran my
rifle so hot it would burst into flames. This is a point well taken,
if you are going to run your gun hard, it would definitely be better
to stick with Mobil1. You can always clean it with ATF after it
dips below 300 degrees F.
Unless you want that "Ghost Rider" effect...
