I use NOTHING but synthetic stuff for every application in the world. Been using it for over 25 years. All except for the Hydro oil that I just replaced.
IMO:
Synthetic by far beats all oil based & lithium base's. Proven fact.
Guns,
Fishing reels,
Cars,
Truck,
etc.
Heck they issue nothing but synthetic oil for the maintenance of the M-4's for the military.
Don't wanna get into no comparison's with others but I wish they made it so I could drink it.
