I would be hesitant to run anything thinner that a 40 wt. due to such low oil pressure on these when hot. Mine run a power take off at idle and warm oil pressure idling on any flathead will always require a second look.
I will recommend MMO as a gas additive, along with stabil. It seems to keep the combustion chambers/spark plugs cleaner, but as mentioned mine idle 98% of run time.
Thanks roadrunner1, we still have my father's '48 Ford F-6 boom truck with PTO that we used to lift cars with in the junkyard. He bought a Ford flathead 8BA rebuild crate engine back in the '60's for it. Running ever since. Not as much use now, the junkyard is gone. I use Stabil for mine, MMO I still need to know more science, but I respect the advice, my Dad swore by MMO,
