Re: lowest oil pressure for engine to survive
That sounds about right for 20/50 when it warms
up. You are going to get "stories" of 3 or 4 lbs is
OK but don't believe them. It takes a fair amount
of oil to get a good flow into the bearings. A good
flow also cools the oil when it splashes off the crank
shaft. With an oil temp gauge on an open highway
you can watch the oil temp go up as the engine works
going up hill and cool down as it comes back down hill.
Had fun watching it in my motor home on long trips. G.M.
