That is where I like to run mine, no Lower..Maybe at times a little higher BUT never up tight to full... The thing is when I get 1000 miles on That oil change, I usually put in about 3 oz new oil to freshen up the Old oil a bit..
it is Still on the Below full level.. I do use the full 3.5 quarts in my change... At times, I have added oil to with-in a 1/4 inch LESS of the full line... Usually after a few miles like said above to FRESHEN the oil..
I use Redline 20/50 premium synthetic oil..
MTL in the primary
Shockproof Heavy in the tyranny
